Tropical Storm Sally is forecast to intensify into a hurricane Monday and slowly edge toward the coastline of Louisiana, Alabama and Mississippi, where it is forecast to push a dangerous surge ashore and unload tremendous rainfall through Wednesday.
The storm is slowly crawling west-northwest toward the Gulf Coast and its assault on the coast will be prolonged. Before landfall, Sally may intensify further over the warm waters of the Gulf of Mexico.
While its strong winds will get plenty of attention, potentially bringing 70 to 90 mph winds to New Orleans, this storm’s greatest threat is water. This part of the Gulf Coast is extremely vulnerable to storm surge flooding, which refers to the storm-driven rise in water above normally dry land at the coast.
