Hurricane Katrina from TRMM: …
Title Hurricane Katrina from TRMM: August 29, 2005
Abstract NASA's TRMM spacecraft is used to understand Hurricane Katrina. TRMM observed this view of Hurricane Katrina just before the storm made landfall on August 29, 2005. Katrina remains an extremely large and dangerous hurricane. Hurricane force winds extend outward up to 105 miles from the storm's center. Coastal storm surge flooding of 18 to 22 feet above normal tide levels are expected. The cloud cover is taken by TRMM's Visible and Infrared Scanner(VIRS) and the GOES spacecraft. The rain structure is taken by TRMM's Tropical Microwave Imager (TMI). It looks underneath of the storm's clouds to reveal the underlying rain structure. Blue represents areas with at least 0.25 inches of rain per hour. Green shows at least 0.5 inches of rain per hour. Yellow is at least 1.0 inches of rain and red is at least 2.0 inches of rain per hour.

Title Floods in Texas and Louisiana
Description Smudges and pools of black—tale-tell signs of flooding—outline the Neches, Sabine, and Calcasieu Rivers in the top satellite image. Taken by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite on October 24, 2006, the image was created with both infrared and visible light, a combination that makes water appear black, while plant-covered land is green. The floods that the image reveals occurred after heavy rain [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13933 ] inundated Texas and Louisiana. The Neches, Sabine, and Calcasieu swelled as inland runoff drained through the rivers. By October 23, the Neches River was eight feet above flood stage near Beaumont, Texas, reported the Associated Press [ http://www.cnn.com/2006/US/10/23/texas.floods.ap/index.html ]. The floods destroyed about 40 homes in Beaumont, a region that was still recovering from a direct hit from Hurricane Rita [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13166 ] in 2005. Cement-gray against the verdant landscape in these images, the city of Beaumont sits on the west bank of the Neches River. Smaller cities pepper the distance between Beaumont and its southern neighbor, Port Neches. Patches of tan are sparsely vegetated or plant-free stretches of land. Red boxes outline a few fires in the lower image, which was taken before the rain began. Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?USA7/2006297 ] of the U.S. Gulf Coast are available from the MODIS Rapid Response Team in both false color, as shown here, and photo-like, true color.

Hurricane Dennis
Title Hurricane Dennis
Description Hurricane Dennis was bearing down on the Gulf Coast of the United States on July 10, 2005, at 12:15 p.m. (16:15 UTC) when the Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov/ ] on NASA?s Terra [ http://terra.nasa.gov/ ] satellite captured this image. With winds of 135 miles per hour (217 kph), Dennis was a powerful Category 4 storm just hours away from making landfall. At the time this image was taken, the eye of the storm was about 55 miles (90 kilometers) south, southeast of Pensacola, Florida, and the storm was moving northwest at about 18 miles per hour (29 kph). The size of the storm put clouds of rain over most of the southeastern United States well before the storm came ashore. In this image, Dennis covers all of Florida, Alabama, Mississippi, and stretches over parts of Louisiana. The northern fringes of the storm appear to be over Tennessee and North Carolina. For additional information and warnings about this storm, please visit the National Hurricane Center. This image is available in additional resolutions from the MODIS Rapid Response Team.

Hurricane Katrina
Title Hurricane Katrina
Description Hurricane Katrina moved ashore over southeast Louisiana and southern Mississippi early on August 29, 2005, as an extremely dangerous Category 4 storm. With winds of 135 miles per hour (217 kilometers per hour), a powerful storm surge, and heavy rains, Katrina pounded the U.S. Gulf Coast, triggering extensive life-threatening flooding. This GOES image shows the storm as it moved over southern Mississippi at 9:02 a.m. The eye of the storm is due east of New Orleans, Louisiana. Katrina continued to move north into Mississippi, and is expected to track northeast across the United States into Eastern Canada over the next two days. By mid-afternoon on August 29, Katrina had weakened into a Category 1 hurricane with winds of 95 mph (153 km/hr). A mere 24 hours earlier, Katrina had been one of the most powerful storms ever observed in the Atlantic Basin. The above animation tracks the storm's degradation from a Category 5 storm on August 28, to a Category 1 storm on August 29 as the storm spent its fury on Louisiana and Mississippi. The first image in the animation was taken at 7:15 p.m. CDT on August 28. At this time, Katrina was well-organized, with a large eye. The storm had winds of 160 mph (258 km/hr) with stronger gusts and a central pressure of 902 millibars. The lower the air pressure associated with a hurricane, the more powerful the storm tends to be. Since records began, only three storms have ever had lower air pressures. Katrina was a very powerful and extremely dangerous Category 5 storm. As the storm moved north through the night, it weakened slightly into a Category 4 storm before slamming ashore over southeastern Louisiana around 6 a.m. As the storm moved ashore during the day, it gradually lost its distinctive eye and weakened to the Category 1 storm seen in the final frame, taken at 2:45 p.m. on August 29. For more images of Hurricane Katrina, please visit the Natural Hazards [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13081 ] section of the Earth Observatory.

Hurricane Katrina
Title Hurricane Katrina
Description Hurricane Katrina was sprawled across all or part of 16 states at 2:15 p.m. CDT on August 29, 2005, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image. After nearly eight hours over land, Katrina was still a Category 1 storm, with winds of 150 kilometers per hour (95 miles per hour) and stronger gusts. In this image, Katrina measures about 1,260 kilometers (780 miles) from east to west and about the same distance from north to south across its center. While most states under its clouds have only experienced rain so far, Louisiana, Mississippi, Alabama, and Florida have all been pummeled by furious winds, heavy rain, and a powerful storm surge. Katrina was a strong Category 3 storm when its eye moved ashore earlier in the day. The large image provided above has a resolution of 500 meters per pixel. The MODIS Rapid Response Team provides the image in additional resolutions, including MODIS' maximum resolution of 250 meters per pixel.

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 Erodes the U.S. Gulf Coast
Description The graceful curve of the Chandeleur Islands resembles a multi-boned spine connecting the Mississippi Gulf coast to the delta of the Mississippi River in Louisiana. Like all barrier islands, the Chandeleur Islands form a thin protective wall between the open sea and the mainland, in this case Louisiana's St. Bernard Parish. The islands absorb the strongest waves, sheltering the mainland during large storms. It is no surprise, then, that barrier islands along the U.S. Gulf Coast changed dramatically in the wake of Hurricane Katrina, and no change is as dramatic as that seen in the Chandeleur Islands. Hurricane Katrina's strong winds, storm surge, and battering waves scoured the islands, leaving them reduced or gone altogether. These images of the islands were taken by the Landsat 5 satellite. The top image, taken on September 16, 2005, shows the Mississippi and Alabama coast line, including the line of islands that bore the brunt of Katrina's fury. The lower images show the northern section of the Chandeleur Islands at full resolution. In the 11 months that passed between October 15, 2004, when the right image was taken, and September 16, 2005, when the left image was taken, the islands have wasted away. Barrier islands like the Chandeleur Islands are constantly building, eroding, and shifting under the normal actions of wind and waves. A powerful storm like Katrina can produce changes that otherwise may have taken many years, and most of the change seen here is probably a result of Katrina. Hurricane Dennis also gave the islands a glancing blow on July 10, 2005, and may be responsible for some of the change. The other barrier islands shown in the top image were also scoured by Katrina. The large images show that the Ship Islands [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13130 ] are now significantly smaller than they were in 2004, and Dauphin Island [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13132 ] has been cut in two.

Title Hurricane Katrina Floods the Southeastern United States
Description In the wake of Hurricane Katrina, much of New Orleans is under water in the top satellite image, taken on August 30, 2005, at 11:45 a.m. CDT by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite. Early news reports say that as much as 80 percent of the city is flooded after levees failed to hold Katrina's massive storm surge back. The flooding is getting worse as water slowly seeps into the city from Lake Pontchartrain. On Saturday, August 27, 2005, New Orleans formed a tan and green grid sandwiched between the lake shore and the river in the lower image. Three days later, dark pools of water covered the eastern half of the city, and a large section of Lake Pontchartrain ballooned into the region immediately west of the city. Widespread flooding is visible elsewhere in the top image. Lake Pontchartrain and Lake Maurepas have nearly blended into a single body of water, separated only by a narrow strip of land. Dark smudges line the rivers flowing into both lakes, a sign that water covers the ground around them. The images are shown in false color to make water visible against the land. Water is black or dark blue where it is colored with mud, vegetation is bright green, and clouds are light blue and white. The large images provided above provide a broader view of the region.

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.

Description The Louisiana Superdome is now an island refuge for as many as 30,000 people, according to news reports. Many sheltered in the stadium while Hurricane Katrina raged overhead on Monday, August 29, 2005, and many more have been brought to the Superdome after being rescued from their flooded homes. The stadium itself was surrounded by flood water when the QuickBird satellite captured this detailed image on August 31. Much of the stadium's bright white roof is missing, though the underlying roof structure appears to be intact. Interstate 10 runs along the lower edge of the image. In the large version of the image, provided in the link above, the flooding stops just a few blocks away from the stadium. While safe from the floods, several downtown buildings show signs of wind damage. Image copyright Digital Globe [ http://www.digitalglobe.com/index.php ].

Title Hurricane Katrina Floods the Southeastern United States
Description New Orleans was still severely flooded when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured the top image on August 31, 2005. Taken two days after Hurricane Katrina battered the region, the image shows widespread flooding around Lake Pontchartrain. In these false-color images, water is black or dark blue, vegetation is green, and clouds are light blue and white. Land that has been flooded is a deep green in the top image. Outside of New Orleans [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13094 ], the floods are most severe on the east side of Lake Pontchartrain. The land separating the lake from Lake Borgne is either saturated or completely covered with water. A wedge of the northeast shore of Lake Pontchartrain is also underwater. On the west side of the lake, conditions seem to be improving. On August 30 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13089 ] the northwestern shore of Lake Pontchartrain had disappeared, blending into Lake Maurepas to the west. By August 31, the shore had reappeared, though it is still darkened with flood water. The large images provided above are at MODIS' maximum resolution of 250 meters per pixel. Both the August 31 and August 27 images 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 Hurricanes form over tropical waters, encouraged by sea surface temperatures of 26.5 °C (80 °F) or higher. Over such warm waters, hurricanes can explode in size and intensity, becoming Category 4 or 5 storms by the time they make landfall. Like its predecessor Katrina, Hurricane Rita has picked up steam in its trip over a warm Gulf of Mexico. The dark grey circles show measured positions of the hurricane, while lighter grey circles show forecasted positions. Maximum sustained wind speeds at each location are shown in miles per hour (white numbers). A quartet of satellites, including NASA's Topex/Poseidon and Jason satellites, have monitored sea surface height during Rita's journey toward the Gulf Coast. This map results from a combination of data from these satellites collected on September 21, 2005. This image shows ocean circulation patterns in the Gulf of Mexico, framed by the Florida peninsula on the right and the Texas-Mexico Gulf Coast on the left (shown in gray). Red indicates strong circulation of warm waters. Sea surface height is a useful measure of potential hurricane activity because storm-fueling warm water is higher than surrounding cooler water. The area shown in red is approximately 35 to 60 centimeters (roughly 13 to 23 inches) higher than the surrounding Gulf. A hurricane's track depends primarily on the winds that steer it, and these winds are forecasted with atmospheric models. The hurricane's energy source, however, comes from the ocean. Hurricanes travel over both strong ocean currents and smaller currents running in different directions (eddies). As of September 22, 2005, Hurricane Rita was forecasted to continue crossing a circulation feature in the Gulf of Mexico known as the Loop Current, then pass near a warm-water eddy known as the Eddy Vortex. The Eddy Vortex is in the north central Gulf, south of Louisiana. The Jason satellite carries a radar altitude meter, otherwise known as an altimeter. To determine the ocean's height, the altimeter measures the time it takes for the microwave pulses to bounce off the surface and return to the spacecraft. This measure, multiplied by the speed of light, gives the range from the satellite to the ocean surface. The joint U.S.-French Topex/Poseidon mission is managed by NASA's Jet Propulsion Laboratory.

Hurricane Rita
Title Hurricane Rita
Description Rita became a Category 5 hurricane late on September 21, 2005, with sustained wind speeds of 275 kilometers per hour (170 miles per hour), making it the fourth most powerful storm ever measured. It was easing off this strength slightly by mid-day September 22 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 12:55 p.m., U.S. Eastern time. The storm bears the markings of a powerful hurricane: it is compact and circular, though clouds have formed in the eye of the storm. This closed or "dirty" eye shape is typical of a storm which has reached its peak strength and is slackening. However, Rita remained a remarkably powerful storm. At the time this image was acquired, Rita had winds of 250 kilometers per hour (155 miles per hour) with gusts as high as 310 km/hr (195 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. The air just below the cloud banks of Rita is remarkably clear, where wind and pressure patterns caused by the storm have banked polluted air away to the north and west. The large image has a resolution of 250 meters per pixel. It is available in additional resolutions [ http://rapidfire.sci.gsfc.nasa.gov/gallery/?2005265-0922/Rita.A2005265.1655 ] from the MODIS Rapid Response Team.

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.

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's fifteen-foot storm surge and heavy rains caused widespread flooding along the Louisiana coastline. The storm came ashore near the Texas and Louisiana border on September 24, 2005, and the region was still flooded two days later, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) captured the top image. In the false-color image, water is black or dark blue where it is colored with mud. The storm burst through levees lining canals, lakes and bayous throughout southeastern and central Louisiana. Water poured into low-lying areas, leaving much of the region flooded to such a degree that the large lakes that lined the coast are no longer distinguishable from each other. Though many buildings and farms have largely been destroyed, the death toll remains low because most people evacuated before the storm struck. As Rita moved inland, the storm's heaviest rains fell on Louisiana. (See Hurricane Rita [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13165 ] on the Earth Observatory for rainfall totals.)

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.

Title Fires in Southern United States
Description Drought, high temperatures, and strong winds combined with holiday fireworks, trash fires, and careless cigarettes to create a disaster in parts of Texas and Oklahoma in late December 2005. According to the Associated Press, more than 70 fires blazed throughout north and central Texas and Oklahoma, many of them set by people ignoring local fire bans. By December 29, nearly 20,000 acres had burned in the region, more than 100 homes had been lost, and several people had died from fire-related injuries. This image shows parts of Texas, Oklahoma, Arkansas, and Louisiana, as imaged by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard the Aqua [ http://aqua.nasa.gov/ ] satellite. The sensor took this image on December 28, 2005, the same day that the fires caused the most damage. Cloud cover obscures part of the region, but hot spots, indicated in red, appear throughout the area, many of them sending up their own plumes of smoke. North and central Texas, where most of the fires occurred, saw its fifth driest year on record in 2005. In the Dallas-Forth Worth area, annual rainfall was about 41 centimeters (16 inches) below normal. In Oklahoma, the annual rainfall was about 30 centimeters (12 inches) below normal. Shortly before the grass fires spread throughout the region, local temperatures topped 27 degrees Celsius (80 degrees Fahrenheit) and worsened the already-dry conditions. The wind and heat abated somewhat after the fires started, but the National Weather Service predicted a return of heat and wind right before New Year's Day of 2006. Authorities expressed concern that a fresh round of holiday fireworks could touch off a fresh round of fires.

Tropical Storm Cindy
Title Tropical Storm Cindy
Description Tropical Storm Cindy was preparing to make landfall over southeastern Louisiana on July 5, 2005, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image. At the time, National Hurricane Center [ http://www.nhc.noaa.gov/ ] reported the storm to have winds of 70 miles per hour, just 4 miles per hour under hurricane status. After coming ashore near the mouth of the Mississippi River, Cindy moved northeast, drenching Alabama with rain. Though the storm left thousands without power and triggered some flooding, no serious damage has been reported. The large image provided above is at MODIS' maximum resolution of 250 meters per pixel.
