Fay, the tropical storm that wouldn't go away, has weakened to a tropical depression, but forecasters warn it could still drop up to a foot of rain along its path over northwest Florida, Alabama, Mississippi and Louisiana.
Fay was marching west-northwestward at 10 mph Sunday morning, and forecasters warned that the storm could spawn isolated tornadoes Sunday in the Florida Panhandle, western Georgia and Alabama. Watch trapped residents get rescued »

Fay's disorganized center was about 60 miles east-northeast of Mobile, Alabama, and about 30 miles north-northeast of Pensacola, Florida, the hurricane center advisory said.
Radar measured Fay's top sustained winds at about 35 mph late Saturday, and it is expected to gradually weaken over the next two days, the center said.
"Fay is expected to produce total rainfall accumulations of 6 to 12 inches across the extreme western portion of the northern Florida Peninsula, the Florida Panhandle, southwestern Georgia, the southern and central portions of Mississippi and Alabama and eastern Louisiana," the hurricane center said.
It also said some areas could get as much as 20 inches of rain.
While all tropical storm warnings and watches have ended, emergency officials along the Gulf Coast are braced.
In New Orleans, a famously low-lying city, the Army Corps of Engineers said its canal flood-watch teams have been activated as a precaution.
In anticipation of the storm's westward movement, teams will "mobilize to their duty stations 8 a.m. Sunday, and monitor canals and levees in the city," the Corps said in a written statement Saturday.
Col. Alvin Lee, New Orleans District commander, said the actions were "precautionary measures for the safety of the public."
"However, we are prepared to close the gates and run the pumps should the need arise," he said.
The Corps took responsibility after Hurricane Katrina flooded most of New Orleans in 2005 for not having built sufficient levees against flooding.
The National Hurricane Center said isolated areas of eastern Louisiana could have up to 20 inches of rain.
Mobile County, Alabama, opened five shelters and called in swift-water rescue teams in anticipation of flooding, said Steve Huffman, spokesman for the county's emergency management agency.
"The storm is actually weakening. That's not to say we're not going to have rain," Huffman told CNN. "We're still expecting some flooding because of this. We've got everything on standby -- hopefully it won't come to that."
