Document Title: Hurricane Katrina at landfall, water vapor band (DI01933) Image generated by Jeff Weber
Description: The peak winds of over 100 miles per hour that buffeted New Orleans during Hurricane Katrina could have been much worse had the storm made landfall at a different moment in the cycle of its eyewall. Long-lived, intense hurricanes often go through an eyewall replacement cycle that takes a day or so to complete. The result is collapse of the main eyewall and temporary weakening of the storm. This water vapor band image shows Katrina's weakened eyewall being further disrupted by interaction with the land surface at 5:45 a.m. on Monday, August 29, 2005. Jeff Weber, UCAR scientist, generated this image using GEMPAK software and data from the water vapor and infrared bands of NOAA's GOES-E satellite.
