The hurricane strengthened rapidly as it passed through the Gulf of Mexico, fed by its warm water. This satellite imagery from the National Oceanic and Atmospheric Administration shows water vapor in the atmosphere as the storm made landfall.
More than 16 inches of rain fell in some parts of Louisiana as the storm moved through the region. The flood-protection system built around New Orleans after Hurricane Katrina appears to have succeeded at preventing catastrophic flooding in the city.
