Tropical Cyclone Glenda
| Title |
Tropical Cyclone Glenda |
| Description |
Tropical Cyclone Glenda formed off the northwestern coast of Australia on March 27, 2006. The storm quickly built into a powerful and well-defined cyclone during the next day. Powerful winds have whipped up surf along the coastline of Western Australia's Pilbara region, and the storm also brought heavy rain to the islands off the Kimberly coast. As of March 28, 2006, the storm had reached Category 4 status and was expected to build power and reach the maximum, Category 5, rating during the next day. This natural-color image was acquired by the Moderate Resolution Imaging Spectrometer (MODIS) on the Terra satellite on March 28, 2006, at 10:00 a.m. local time (02:00 UTC). It shows Cyclone Glenda as a well-developed storm, sitting 180 kilometers (150 miles) north of Broome. The storm was already large enough that Broome was covered by the edge of the cyclone. Sustained, peak winds in the storm system were roughly 165 kilometers per hour (105 miles per hour) at this time. The cyclone had been traveling roughly parallel to the coastline, putting the entire coastal area on alert. The area includes not only major pearl-diving operations and beaches that attract tourists, but it is also home to the Northwest Shelf, one of Australia's major oil fields. The oil fields are located off the coast near Dampier. According to news reports, operators were not expressing concern about the oil field but were planning for necessary shutdowns for safety.

Tropical Cyclone Glenda formed off the northwestern coast of Australia on March 27, 2006. The storm quickly built into a powerful and well-defined cyclone during the next day. Powerful winds have whipped up surf along the coastline of Western Australia's Pilbara, and the storm brought heavy rain to the islands off the Kimberly coast. As of March 29, 2006, the storm had reached Category 5 status, the maximum rating possible for a cyclone. This photo-like image was acquired by the Moderate Resolution Imaging Spectrometer (MODIS) on the Terra satellite on March 29, 2006, at 10:40 a.m. local time (02:40 UTC). It shows Cyclone Glenda as a well-developed storm, sitting 525 kilometers (330 miles) west of Broome. Clouds from the storm covered most of the northwest coastline of Western Australia. Sustained, peak winds in the storm system were roughly 220 kilometers per hour (140 miles per hour) at this time. The storm's spiraling clouds appear as a nearly solid white disk, but in several places, it appears as though some clouds are "boiling" up above the rest. Predictions as of 2:55 a.m. Australian Western Standard Time on March 30 were that the storm would cross the coast between Exmouth and Karatha on Thursday afternoon or night as a very dangerous storm. The Australian Bureau of Meteorology predicted that wind speeds near the storm center could reach 265 kilometers per hour (165 miles per hour) as the storm comes ashore. Many coastal communities were being evacuated by State Emergency Services ahead of the storm.

| Description |
Tropical Cyclone Glenda formed off the northwestern coast of Australia on March 27, 2006. Powerful winds whipped up surf along the coastline of Western Australia's Pilbara region, and the storm brought heavy rains to the islands off the Kimberly coast. On March 29, it was classified as a Category 5 storm, the highest rating on the cyclone-strength scale. However, as it came ashore a day later, it had lost a small fraction of its strength. By March 31, 2006, the storm had lost considerable power and was ranked as a mere tropical depression. This photo-like image was acquired by the Moderate Resolution Imaging Spectrometer (MODIS) on the Terra satellite on March 31, 2006, at 10:30 a.m. local time (02:30 UTC), roughly 40 hours after coming ashore near Onslow. The remnants of Cyclone Glenda still have a vaguely spiral appearance, but they lack the well-developed eye and tight-wound shape of the mature, powerful storm of previous days. Clouds from the storm cover most of the Indian Ocean coast of Western Australia. Sustained, peak winds in the storm system were considerably diminished, roughly 65 kilometers per hour (40 miles per hour) around the time the image was captured. Damage assessments in Onslow showed the town fared better than expected in the face of such a powerful storm. However, it will be many days before clean-up operations are concluded. Meteorologists were also concerned about the widespread flooding potential as the storm continued to travel inland.
