Katrina's Satellite Progression Video

Hurricane Katrina appeared suddenly in the Bahamas, moved quickly across southern Florida, intensified to category 5 in the warm-water, mild-wind conditions in the Gulf of Mexico, and then came ashore just east of New Orleans, eventually rupturing the levees and flooding the city. The day/night animation is composed of GOES-12 visible/infrared images of the clouds on top of a color Landsat map.
