Hurricane Katrina

This is an image of Hurricane Katrina on Sunday, August 28, 2005 at 5:30 PM EDT (21:33 UTC) as seen by the Tropical Rainfall Measuring Mission (TRMM) satellite's PR (Precipitation Radar), VIRS (Visible Infrared Scanner), TMI (Tropical Microwave Imager) and the GOES spacecraft. 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. NASA

Hurricane Katrina06 June 2005:

In fiscal year 2006, the New Orleans district of the U.S. Army Corps of Engineers is bracing for a record $71.2 million reduction in federal funding. It would be the largest single-year funding loss ever for the New Orleans district, Corps officials said. I've been here over 30 years and I've never seen this level of reduction, said Al Naomi, project manager for the New Orleans district... The cuts mean major hurricane and flood protection projects will not be awarded to local engineering firms. Also, a study to determine ways to protect the region from a Category 5 hurricane has been shelved for now.
