Progression, Sea Surface Temps, and Rainfall Accumulation of Katrina
Data from the Tropical Rainfall Measuring Mission (TRMM) satellite show heavy rainfall deposited by Hurricane Katrina from August 23 - 30. Red indicates rainfall of 80 millimeters (mm) or more, yellow indicates rainfall of 40 mm. Click on top image to view animation

A hurricane needs ocean water at 82 degrees or warmer to strengthen. This image shows the sea surface temperature in the Caribbean Sea and the Atlantic Ocean, from August 23-30. Every area in yellow, orange or red represents 82 degrees Fahrenheit or above. The data came from the Advanced Microwave Scanning Radiometer (AMSR-E) instrument on NASA's Aqua satellite.
