In addition, the center is calling for an “extremely dangerous and life-threatening storm surge” in coastal areas, though forecasts for surge heights have been lowered.
Torrential rain and tropical storm-force winds walloped coastal Alabama and the Florida Panhandle on Tuesday, and the storm’s effects are expected to intensify as Sally comes ashore Wednesday morning near the Alabama-Florida border.
Sally’s plodding motion means a relentless pounding from wind and water lasting well into Wednesday.
The surge could cause the water to rise up to six feet above normally dry land in parts of coastal Alabama, including Mobile Bay, and coastal inundation could persist over multiple tidal cycles.
Wind gusts over 70 mph are likely to cause damage, downed trees and widespread power outages, especially close to where Sally comes ashore. Tornadoes could also be embedded in rain bands that move ashore.
