Floods in Southeast Texas
Title Floods in Southeast Texas
Description Strong southerly winds pumped moist air up from the Gulf of Mexico and across southeastern Texas over the Memorial Day weekend at the end of May 2006. The abundant moisture triggered and sustained thunderstorms over the coastal areas of Texas between May 28 and May 31, 2006. Up to 16 inches of rain were reported in just 24 hours in Chambers County, Texas, east of Galveston Bay, and nearly 12 inches of rain fell in Harris County just outside of Houston. Patches of heavy rain in Southern Texas are clear in this image of satellite-based rainfall totals for May 28-31, 2006. The highest totals (shown in red) occur just inland from the coast near Matagorda Bay along the central part of the Texas Gulf coast where rainfall totals exceed 10 inches (darkest red area). Another area of heavy rain is visible near the border with Louisiana just north of Beaumont, Texas, where amounts are on the order of 7 inches (lighter red area). The totals reported near Galveston Bay and Houston may have been too small in scale (occurred in a very localized area) or occurred over too a brief period to be captured by the satellite, as the image shows relatively low totals in those areas. The image was created from a near-real time, Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center. The MPA is based on data from the Tropical Rainfall Measuring Mission satellite (known as TRMM, [ http://trmm.gsfc.nasa.gov/ ]) which was placed into service in November 1997. From its low-Earth orbit, TRMM has been measuring rainfall over the global Tropics using a combination of passive microwave and active radar sensors. TRMM is a joint mission between NASA and the Japanese space agency, JAXA. Image produced by Hal Pierce (SSAI/NASA GSFC) and caption by Steve Lang (SSAI/NASA GSFC).
Hurricane Katrina
Title Hurricane Katrina
Description After forming in the central Bahamas, Katrina came ashore in south Florida as a Category 1 hurricane where it was responsible for 11 fatalities. The storm cut diagonally across the southern part of the state from just north of Miami on the east coast, through the Everglades, to Cape Sabel on the west coast. In the process, Katrina brought heavy amounts of rain to parts of south Florida and Cuba. This image shows the Multi-satellite Precipitation Analysis (MPA) rainfall totals due to the passage of Katrina for the period August 23 to 31, 2005. Storm symbols mark the track of Katrina at 0:00 UTC (8 p.m. Eastern Daylight Savings Time (EDT) on the previous day), plus symbols are the location of Katrina at 12:00 UTC (8 a.m. EDT). The solid hurricane symbol represents a hurricane, the hollow symbol is a tropical storm, while a circle marks a tropical depression. The highest rainfall totals exceeded 12 inches of rain (dark red areas) over northwestern Cuba and the lower Florida Keys. Amounts over the southern Florida peninsula were between 5 and 8 inches (green to yellow area). Local WSR-88D radar esimates were locally much higher just west of Miami, but the overall pattern and amounts over the lower keys were in good agreement with the MPA totals. After entering the Gulf of Mexico, Katrina intensified into a large, powerful Category 5 storm as it turned north towards the north-central Gulf coast. Katrina came ashore as a powerful Category 4 storm over southeastern Louisiana and southern Mississippi, causing catastrophic damage and numerous fatalities. Rainfall totals immediately along the coast of Mississippi were between 6 and 9 inches (yellow to orange) in very good agreement with local radar estimates. After coming ashore, Katrina tracked quickly up through Mississippi, western Tennessee and Kentucky and into Ohio. Katrina's rapid forward progress helped keep rainfall totals down across the central United States with amounts generally less than 5 inches (green to blue) across northern Mississippi and parts of the Ohio valley. The Tropical Rainfall Measuring Mission (TRMM) satellite has been measuring rainfall over the tropics since its launch in 1997. The MPA measures such as those show here are based on measurements by TRMM and other satellites. The MPA measurements are created at the NASA Goddard Space Flight Center to provide estimates of rainfall over the global tropics. TRMM is a joint mission between NASA and the Japanese space agency JAXA. Image produced by Hal Pierce (SSAI/NASA GSFC) and caption by Steve Lang (SSAI/NASA GSFC).

Title Hurricane Katrina Erodes the U.S. Gulf Coast
Description Gulf Coast cities weren't the only land surfaces to take a beating from Hurricane Katrina in August 2005. Barrier islands stretching from Texas to Florida were also scoured by the wind and waves of the powerful storm. Permanent changes to the shape and elevation of Timbalier Island and its northeastern companions are visible in this pair of infrared-enhanced images from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [ http://asterweb.jpl.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite. Timbalier Island, the largest island pictured here, sits at the interface between the Gulf of Mexico (south) and Terrebonne Bay (north) along the Louisiana coast southwest of New Orleans. Compared to the image from 2000 (bottom), a large swath of bright sand dominates the eastern side of Timbalier Island in the September 13 image, having either been piled there or exposed by waves and storm surge. To the east-northeast, two small, curving islands have disappeared completely, while farther north, the fierce seas turned two small slots in a barrier island into a single large gap.

Title Hurricane Katrina Floods the Southeastern United States
Description The Mississippi River pours into the Gulf of Mexico through the wetlands of Louisiana. Over millennia, the river has deposited sediment into the Gulf, slowly building the long "crow's foot" delta seen here. The delta that took thousands of years to build changed dramatically overnight when Hurricane Katrina blew ashore. On August 31, 2005, the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured the top image of the Mississippi River delta. In contrast to the lower image, taken on August 9, 2005, much of the green land is under water. The false-color images show water as black, or dark blue where muddied by sediment, plant-covered land as green, and clouds as pale blue and white. The changes seen in the delta may be a result of temporary flooding brought on by the hurricane's powerful storm surge and heavy rains, or they may be permanent if the storm washed away sections of land. The Mississippi River is clearly swollen in the top image, indicating that the flooding caused by the storm had not subsided by August 31. On the other hand, the water around the delta is blue, clouded with dirt. The dirt could simply be run-off from the floods, or it could be eroded shoreline. The high-resolution images provided above are at MODIS' maximum resolution of 250 meters per pixel. They are available in additional resolutions from the MODIS Rapid Response Team, which provides daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?USA7 ] of the region.

Hurricane Rita
Title Hurricane Rita
Description After forming east of the Turks and Caicos, Rita moved west and sideswiped the Florida Keys before entering the Gulf of Mexico where it strengthend into the 3rd most powerful hurricane on record (in terms of central air pressure). Rita eventually made landfall near the Texas-Louisiana border as a Category 3 storm. After making landfall, Rita weakened into a tropical depression and moved northeastward through central Arkansas and into southeast Missouri. The image about shows the Multi-satellite Precipitation Analysis (MPA) rainfall totals due solely to Rita for the period September 18-26, 2005, with storm symbols marking the storm track. The highest rainfall totals are over coastal Louisiana where a swath of 8- to 10-inch amounts (yellow and orange areas) extends eastward from the Texas border to near Morgan City. Parts of the Keys and far southwestern peninsular Florida received up to 5 inches from Rita (green areas). Overall, the inland rainfall totals across the central Mississippi valley were not very high, generally less than 4 inches (light green to blue), as Rita rather quickly moved off to the northeast. The Tropical Rainfall Measuring Mission (TRMM) satellite has been measuring rainfall over the tropics since its launch in 1997. The TRMM-based, near-real time MPA at the NASA Goddard Space Flight Center provides estimates of rainfall over the global tropics.

Hurricane Rita
Title Hurricane Rita
Description The onslaught from the 2005 hurricane season continued with the arrival of Hurricane Rita, the second Category 5 storm to threaten the Gulf of Mexico in less than a month. As it was passing south of the Florida Keys on September 20, 2005, Hurricane Rita was in the process of slowly intensifying from a Category 1 storm into a Category 2 storm. However, upon entering the Gulf of Mexico, Rita tapped into a deep layer of very warm water located in the southeast part of the Gulf associated with the Loop Current. This allowed Rita to undergo a process known as rapid deepening, which transformed it into a powerful Category 5 hurricane with the 3rd lowest air pressure ever recorded in an Atlantic Basin storm. Fortunately, as Rita moved across the Gulf away from the loop current, it slowly began to weaken. The Tropical Rainfall Measuring Mission (TRMM) satellite observed Rita at 13:45 UTC (9:45 am EDT) on September 23, 2005 as the hurricane was passing south of the central Louisiana coast. The center of the storm lies within the TRMM Microwave Imager (TMI) swath. Areas of very heavy rain (dark red areas) associated with an outer rainband are approaching the the Louisiana coast. The eyewall is not as symmetrical as in earlier observations, one sign of a weakening storm. Rita, however, was still strong with sustained winds of 220 kilometers per hour (140 miles per hour) when this image was taken. The TRMM satellite is one of many being used to monitor hurricanes and typhoons. Launched in November of 1997 to measure rainfall over the tropics, TRMM has proven to be a valuable platform for observing tropical cyclones and can provide unique images and information on these storms. TRMM is a joint mission between NASA and the Japanese space agency JAXA. Images produced by Hal Pierce (SSAI/NASA GSFC) and captioned by Steve Lang (SSAI/NASA GSFC).
Hurricane Rita
Title Hurricane Rita
Description Rita was building into an extremely dangerous Category 5 hurricane when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image at 12:10 p.m., U.S. Eastern time on September 21, 2005. The storm bears the markings of a powerful hurricane: it is compact and circular, with an open eye through which the deep blue waters of the Gulf of Mexico are visible. At the time this image was acquired, Rita had winds of 220 kilometers per hour (140 miles per hour) with gusts to 270 kph (170 mph). Within a few hours, the storm intensified to a Category 5 hurricane with sustained winds of 265 kph (165 mph). Rita is the second Category 5 storm of the 2005 Atlantic hurricane season. The first was Hurricane Katrina, which devastated much of the Mississippi, Louisiana, and Alabama shoreline when it came ashore on August 29. Rita is expected to weaken slightly before coming ashore over the Texas or Louisiana coastline on September 23 or 24 as a major hurricane (Category 3 or higher). In this photo-like image, the Gulf Coast of the United States frames the open water to the north, while the Yucatan Peninsula is visible to the south. MODIS detected several fires, marked with red dots, burning in the southeastern United States. The fires are probably agricultural fires. The large image has a resolution of 500 meters per pixel. It is available in additional resolutions, including MODIS' maximum resolution of 250 meters per pixel, from the MODIS Rapid Response Team.

Hurricane Rita
Title Hurricane Rita
Description Hurricane Rita was slowly winding down as it approached the Louisiana and Texas shoreline on September 23, 2005. At 2:05 p.m. U.S. Central time, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image, Rita was a dangerous Category 3 storm, down from the near-record-breaking Category 5 hurricane it was on September 21. At its core, Rita had sustained winds of 205 kilometers per hour (125 miles per hour) and stronger gusts. A mere two days earlier, the storm packed wind speeds of 275 kilometers per hour (170 miles per hour), making it the fourth most powerful storm ever measured. In this image, the outer bands of the storm already extend well over Texas, Louisiana, Mississippi, and Arkansas, affecting many regions devastated by Hurricane Katrina on August 29. Over the Gulf of Mexico, Rita's well-defined eye has clouded over. This closed or "dirty" eye shape is typical of a storm that has reached its peak strength and is slackening. Though the center of the storm is forecast to come ashore in Texas near the Louisiana border, Rita will likely have a far-reaching effect. The massive storm has hurricane-strength winds that reach 140 kilometers (85 miles) from the eye, with weaker tropical-storm-strength winds that extend as far as 335 kilometers (205 miles) from the storm's center. Rita will also bring heavy rain—up to 20 inches in some locations, the National Hurricane Center [ http://www.nhc.noaa.gov/ ] warns—high tides, and battering waves.

Title Hurricane Rita Floods U.S. Gulf Coast
Description Hurricane Rita pummeled the Louisiana and Texas shoreline when it came ashore on September 24, 2005. Though the Category 3 storm spared major cities, it left much of the southwestern and central Louisiana shoreline under water. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the top image of the floods on September 25, 2005. The trailing edge of Rita's clouds, light blue and white in this false-color image, still cover the region. The shoreline resembles a line of barrier islands fringing a large bay more than the solid coast that existed four days earlier, lower image. Many of the communities most severely affected by the storm are shown in these images, including hard-hit Lake Charles and Cameron, Louisiana. Lake Charles isn't clearly visible under the clouds, but traces of dark blue beneath the clouds hint at flooding in the region. Cameron and other coastal communities like Pecan Island and Grand Chenier (located on the shore just east of the plume of smoke seen in the lower image) appear to be almost entirely under water. Offshore, sediment swirls in the waters of the Gulf of Mexico, coloring the water blue in contrast to its normal inky black. The sediment is probably a combination of sludge stirred up from the ocean floor when Rita's winds and rains churned Gulf waters and run-off from the extensive flooding seen in this image. The large images provided above are at MODIS' maximum resolution of 250 meters per pixel.

Title Phytoplankton Bloom in the Gulf of Mexico
Description . NOTE: All SeaWiFS images and data are for research and educational use only. All commercial use of SeaWiFS data must be coordinated with ORBIMAGE [ http://www.orbimage.com/ ]., A dark green plume of phytoplankton extends away from the crow?s foot of the Mississippi River Delta in this image, acquired on December 13, 2004, by the Sea-viewing Wide Field-of-view (SeaWiFS) Sensor flying on the OrbView-2 satellite. Phytoplankton blooms usually occur where cold water rushes up from the bottom of the ocean carrying nutrients to sunlit waters. In this case, the bloom may be related to recent flooding along the Mississippi River and its tributaries. Heavy rains early in December triggered floods [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=12619 ] across the southeastern United States. The draining flood water carried agricultural run-off into the Mississippi River and the Gulf of Mexico, and that may have provided the nutrients the microscopic ocean plants needed to thrive. In the above images, the Red River twists across southeastern Louisiana from the upper left corner and pours into the Mississippi River beneath the cloud bank. Also concealed by clouds, the Mississipppi drains into the Gulf of Mexico, but just beyond the river?s mouths, the Gulf of Mexico is green with phytoplankton. The lower image shows high chlorophyll concentrations, yellow, corresponding to the green bloom. Scientists have suspected that phytoplankton blooms such as this one may be connected to agricultural run-off, and a recent study seems to confirm this. Using images from NASA?s SeaWiFS sensor, scientists from Stanford University?s School of Earth Sciences compared the timing of irrigation along the west coast of Mexico and phytoplankton blooms in Mexico?s Sea of Cortez (Golfo de California) and found a close correlation. (See press release [ http://www.stanford.edu/dept/news/pr/2004/agugulf-0112.html ] for more information.) Phytoplankton blooms occurred in the Sea of Cortez shortly after irrigation along the coast carried fertilizers and other agricultural run-off into the sea. The bloom detected in the Gulf of Mexico on December 13 may be similarly linked to agricultural run-off. Phytoplankton are an important source of food for many marine animals, so waters that are rich in phytoplankton usually support a thriving ecosystem. But in some cases, phytoplankton blooms can be deadly to the very ecosystem they typically support. Some blooms, such as red tide, are toxic and result in wide-spread fish deaths. Large blooms can also create dead zones in the ocean?oxygen-poor regions where fish cannot survive? when the plants die. The bacteria that break down the decaying plants consume all of the oxygen, leaving a dead spot. The Gulf of Mexico is annually plagued with one such dead zone every summer near the location of the current bloom.

Heavy rains early in December triggered floods [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=12619 ] across the southeastern United States. The draining flood water carried agricultural run-off into the Mississippi River and the Gulf of Mexico, and that may have provided the nutrients the microscopic ocean plants needed to thrive. In the above images, the Red River twists across southeastern Louisiana from the upper left corner and pours into the Mississippi River beneath the cloud bank. Also concealed by clouds, the Mississipppi drains into the Gulf of Mexico, but just beyond the river?s mouths, the Gulf of Mexico is green with phytoplankton. The lower image shows high chlorophyll concentrations, yellow, corresponding to the green bloom. Scientists have suspected that phytoplankton blooms such as this one may be connected to agricultural run-off, and a recent study seems to confirm this. Using images from NASA?s SeaWiFS sensor, scientists from Stanford University?s School of Earth Sciences compared the timing of irrigation along the west coast of Mexico and phytoplankton blooms in Mexico?s Sea of Cortez (Golfo de California) and found a close correlation. (See press release [ http://www.stanford.edu/dept/news/pr/2004/agugulf-0112.html ] for more information.) Phytoplankton blooms occurred in the Sea of Cortez shortly after irrigation along the coast carried fertilizers and other agricultural run-off into the sea. The bloom detected in the Gulf of Mexico on December 13 may be similarly linked to agricultural run-off. Phytoplankton are an important source of food for many marine animals, so waters that are rich in phytoplankton usually support a thriving ecosystem. But in some cases, phytoplankton blooms can be deadly to the very ecosystem they typically support. Some blooms, such as red tide, are toxic and result in wide-spread fish deaths. Large blooms can also create dead zones in the ocean?oxygen-poor regions where fish cannot survive? when the plants die. The bacteria that break down the decaying plants consume all of the oxygen, leaving a dead spot. The Gulf of Mexico is annually plagued with one such dead zone every summer near the location of the current bloom.

Title Severe Thunderstorms over the Southeastern United States
Description Up to ten inches of rain fell over parts of Houston, Texas, between October 10 and October 17, 2006. The rain fell as a line of strong storms, fueled by moisture being pulled up from the Gulf of Mexico, swept across the southeastern United States. Several tornados and deadly flooding were reported across the region. Four people died as a result of the flooding around Houston, said news reports. The top image shows rainfall totals over the southeastern United States for October 10 through October 17, 2006. The rainfall totals come from the near-real-time, Multi-satellite Precipitation Analysis, which is partially based on rainfall measurements made by the Tropical Rainfall Measuring Mission satellite (TRMM [ http://trmm.gsfc.nasa.gov/ ]). The highest totals, shown in red, are around 12 inches (300 millimeters) and occur over north-central Louisiana. Ten-inch (250-millimeter) amounts (lighter red) are visible north of Galveston Bay, and most of eastern Texas and western Louisiana received at least 5 inches (130 millimeters) of rain (green areas). The lower image provides a snapshot of the line of storms at 11:17 p.m. Central Daylight Time on October 16 (4:17 UTC on October 17), as the storm system was passing through central Louisiana. Taken by the instruments on the TRMM satellite, the image shows rain intensity associated with the advancing line of storms. The rains are stretched out in a long, broken line of storms extending from the northwestern Gulf of Mexico through central Louisiana and into southwestern Mississippi. The line of intense rain (dark reds) is relatively thin across Louisiana. A broader area of weaker rain (wide blue and green area) extends farther north. Rain rates in the center swath are from the TRMM Precipitation Radar, a unique space-borne precipitation radar, while rain rates in the outer swath are from the TRMM Microwave Imager. The rain rates are overlaid on infrared data from the TRMM Visible Infrared Scanner. TRMM was placed into service in November of 1997. From its low-earth orbit, TRMM has been measuring rainfall over the global tropics using a combination of passive microwave and active radar sensors. TRMM is a joint mission between NASA and the Japanese space agency, JAXA. Image produced by Hal Pierce (SSAI/NASA GSFC) and caption by Steve Lang (SSAI/NASA GSFC).

Smoke from Alaska Fires
Title Smoke from Alaska Fires
Description Smoke from large forest fires in Alaska has made the rounds across several parts of the Northern Hemisphere since the fires began in mid-June 2004. The plumes of grayish-yellow smoke have drifted across Canada and out to the Atlantic, southward to Louisiana and the Gulf of Mexico, and eastward over the Bering Strait to Russia. In this scene, smoke from fires located in the top center of the scene, in east-central Alaska, is spreading southward along the western arc of the Alaska Range Mountains and the Alaska Peninsula. Below and to the left of center, the smoke breaks eastward across the mountain barrier and streams out over the Gulf of Alaska in two parallel paths?north and south of Kodiak Island. The smoke is getting swirled into a counter clockwise-spinning region of low atmospheric pressure in Gulf. This image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA?s Terra satellite on August 29, 2004.

Title Strong Storms Dump Heavy Rains on Texas and Louisiana
Description An advancing cold front supported by an upper-level trough triggered abundant showers and strong thunderstorms that brought numerous reports of hail and high winds from central Oklahoma through central Texas. The storms also dumped heavy rains over coastal portions of Texas and Louisiana, triggering localized floods, as low-level winds drew moisture up from the Gulf of Mexico. The top image gives a broad snapshot of the storms that led to the heavy rains. The Tropical Rainfall Measuring Mission (TRMM) satellite captured this image at 21:29 UTC (4:29 pm CDT) on May 13, 2004. It shows a horizontal view of rain intensity. Rain rates in the center swath are from the TRMM Precipitation Radar (PR), the first and only precipitation radar in space, and rain rates in the outer swath are from the TRMM Microwave Imager (TMI). The rain rates are overlaid on infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS). TRMM shows a long, broken line of storms beginning with a squall line over southwestern Louisiana with an intense leading edge of (dark reds). The broken line of storms extends all the way back into the southern hill country of central Texas. The large TRMM image also shows a separate area of a few intense, individual thunderstorms over north central Texas. The TRMM satellite uses both passive and active sensors to measure rainfall from space. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center monitors rainfall over the global tropics. MPA rainfall totals for May 7-14, 2004 show peak rainfall amounts of up to 10 to 12 inches (dark red areas) across much of the Texas coast and parts of Louisiana.

Fires in the Southern U.S.
Title Fires in the Southern U.S.
Description Across the southern United States, the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite detected scores of fires burning on March 24, 2003. In the image, the fires have been marked with red dots. At this time of year, the fires can have a variety of causes. Some are prescribed fires being set by state and federal land and forest management agencies to reduce fuels in preparation for the summer wildfire season. A few are wildfires, and others are agricultural fires being used to clear pasture or farmland. The fires are heavily concentrated in Oklahoma (left center), while the fires with the largest smoke plumes are to the east in Arkansas. At bottom center, the Mississippi River flows out into the Gulf of Mexico through Louisiana. The high-resolution image provided above is 500 meters per pixel.

Places where the sensor detected actively burning fires are outlined in red. In Alabama, several individual puffs of smoke are visible in locations where the sensor did not detect a fire. This may be because those fires were not hot enough or large enough for the sensor to register them as "hot spots." A swath of haze lingers over the Gulf of Mexico at lower right. At lower left is the Mississippi River Delta. NASA image courtesy the MODIS Rapid Response Team, [ http://rapidfire.sci.gsfc.nasa.gov ] Goddard Space Flight Center
Thunderstorms Across the Sou …
Title Thunderstorms Across the Southern US
Description An advancing frontal system has brought heavy rains to the Mississippi Valley region and the northern Gulf Coast. Low pressure over the central plains tapped into abundant gulf moisture from the Gulf of Mexico to produce numerous storms ahead of an advancing cold front. Deep-layer southerly winds in front of the low transported warm, moist air up from the Gulf northward into the Mississippi Valley. Storms that formed within this moist air ahead of the cold front deposited significant amounts of rain from eastern Texas up through the Mississippi Valley and over to the Florida panhandle. The continuous regeneration of storms all the way down into the Gulf of Mexico combined with their movement to the north led to an effect known as "training" whereby several different storms pass over the same area. This can lead to significant rainfall accumulations. This image shows rainfall totals for the period 12 to 19 November 2003 from the TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center. A swath of moderate rainfall (green region) of 3-inch plus rainfall extends from East Texas across Louisiana up through the Mississippi Valley and into the Ohio Valley with locally heavier amounts of near 8 inches (in red). A similar pattern extends back into western Missouri and into northeastern Illinois. Moderate amounts fell over the Gulf Coast region from southern Mississippi across the Florida panhandle.TRMM [ http://trmm.gsfc.nasa.gov/ ] is a joint mission between NASA and the Japanese space agency NASDA.

Tropical Storm Allison
Title Tropical Storm Allison
Description The Atlantic Hurricane Season officially began June 1 and almost on cue Tropical Storm Allison formed June 5 in the northwest Gulf of Mexico. A slow-moving storm with sustained winds around 60 miles per hour (97 km per hour), Allison made her way steadily northwestward toward Galveston, Texas. Quite extensive in her reach, Allison packed tropical storm-force winds up to 90 miles (145 km) from the center of the storm. Like an uninvited guest who doesn't know when to leave, Allison is still hanging around a week after she formed, still drawing in moisture from the Gulf and thoroughly soaking the Gulf Coast states from Texas to Florida. In Houston, Texas, Allison dropped as much as 25 inches of rain over the weekend. She dropped another two feet of water in many parts of southern Louisiana. The storm has caused at least 20 fatalities, due to the flooding, high winds and one caused by lightning. In southeastern Texas, roughly 3,500 homes have been damaged by flood waters and many counties have been declared disaster areas. Officials estimate the damage in Texas alone will exceed $1 billion. In this true-color image acquired on June 11 by the Moderate-resolution Imaging Spectroradiometer [ http://earthobservatory.nasa.gov/cgi-bin/redirect?http://modarch.gsfc.nasa.gov/ ] (MODIS), flying aboard NASA's Terra [ http://earthobservatory.nasa.gov/cgi-bin/redirect?http://terra.nasa.gov/ ] satellite, the storm center appears to be located over the Mississippi-Alabama border. Allison continues to move slowly toward the northeast. Today (June 12) her effects are still being felt in the southeastern states of Louisiana, Mississippi, Alabama, Georgia, Florida, and the Carolinas. Meanwhile, the hurricane forecast team at Colorado State University, led by professor William Gray, revised its prediction for the Atlantic Hurricane season. They expect there will be 12 tropical storms this year (up from their original estimate of 10), 7 hurricanes (up from 6), and 3 major hurricanes (up from 2).

Title Tropical Storm Bertha in the Gulf of Mexico
Description Now downgraded to a tropical depression, Tropical Storm Bertha can be seen at full strength in this true-color image taken on August 4, 2002, by the Moderate Resolution Imaging Spectroradiometer (MODIS), flying aboard NASA?s Terra spacecraft. Originating in the Gulf of Mexico, the tropical storm touched land 20 miles (32 kilometers) south of New Orleans, Louisiana, which is covered by clouds in the above image. The storm continued northeast into Mississippi and Alabama, dumping up to five inches of rain in some areas and generating gusts of up to 30 miles (48 kilometers) per hour. Other than the flooding of neighborhood streets, the storm caused no damage. Image courtesy Jesse Allen, NASA Earth Observatory, data provided by MODIS Land Rapid Response Team at NASA GSFC

Title Tropical Storm Bertha in the Gulf of Mexico
Description Remnants of Tropical Storm Bertha dumped heavy rains across parts of Louisiana and Mississippi on August 5, 2002. As much as 6.73 inches of rain fell in Pascagoula, Miss., according to news reports. Meanwhile, another tropical depression formed off the coast of South Carolina on Aug. 5 and is gathering strength. As of Aug. 6, the storm had maximum sustained winds of 35 mph, just 4 mph short of becoming a tropical storm, and was moving slowly eastward. If it continues to intensify, it will become Tropical Storm Cristobol. Elsewhere in this scene, a widespread pall of haze can be seen spanning from Arkansas and Missouri across Tennessee and Kentucky, and into Ohio, West Virginia, and Maryland. Many of these regions received Code Red air quality warnings. Image courtesy Jacques Descloitres, MODIS Land Rapid Response Team at NASA GSFC
