NASA's TRMM spacecraft observed this view of Hurricane Gustav on August 26, 2008 just before it made landfall in Haiti. At this time the storm sustained winds of 75 knots (86 mph) and a pressure reading of 984 millibars. 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) and TRMM's Precitation Radar(PR) instruments. TRMM 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.

Hurricane Gustav on August 27, 2008
NASA's TRMM spacecraft observed this view of Hurricane Gustav on August 27, 2008 as it attacked Haiti. At this time the storm was a category 1 hurricane with sustained winds of 65 knots (75 mph) and a pressure reading of 992 millibars. 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) and TRMM's Precitation Radar(PR) instruments.

Hurricane Gustav on August 31, 2008
NASA's TRMM spacecraft observed this view of Hurricane Gustav on August 31, 2008 as the Gulf Coast braces for the worst. At this time the storm was a category 3 hurricane with sustained winds of 100 knots (115 mph) and a pressure reading of 957 millibars. 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) and TRMM's Precitation Radar(PR) instruments. TRMM 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.

Examining Hurricane Gustav's Cloud Structure
The MODIS instrument on Terra captures great details in the clouds surrounding Hurricane Gustav. Gustav may have been undergoing an eyewall replacement on its approach to the coast – with some weakening. Gustav’s eye looks very small and measures less then 25 nautical miles.The National Hurricane Center indicates that hurricane force winds extended up to 70 miles from the center of the storm threatening much of the Gulf Coast Region.
