The National Hurricane Center says Hurricane Sally will bring flooding rains, inundating storm surge and destructive winds to portions of the Gulf Coast.
The worst of the impacts are forecast in Mississippi and Alabama.
Let's take a look at each of the threats.
RAINFALL:
The National Weather Service has the risk of excessive rainfall the highest from the Florida / Alabama line through Mississippi and into Eastern St. Tammany Parish, New Orleans East, St. Bernard and Plaquemines Parish. Those areas have a 50% chance of flash flooding.
The NOAA estimates call for:
- 20+ inches of rain just onshore in Mississippi
- 15 - 20 inches further inland along Mississippi and Alabama and over lower St. Bernard Parish
- 10 - 15 inches for the eastern Alabama Gulf Coast into the Florida Panhandle
- 10 - 15 inches in Lower Plaquemines and the rest of St. Bernard Parish
- 6 - 10 inches for New Orleans East, Upper Plaquemines and Eastern St. Tammany
- 4 - 6 inches for Jefferson Parish, Orleans Parish (except New Orleans East), Central St. Tammany and Washington Parish
