Tropical Storm Sally has left more than half a million Americans without power as its torrential rains and storm surges lashed the US Gulf coast.
Sally weakened after it made landfall as a Category 2 hurricane but the slow-moving storm continues to batter Florida and Alabama.
At least one person was killed and hundreds were rescued from flooded areas.
“Catastrophic and life-threatening flooding continues over portions of the Florida Panhandle and southern Alabama,” the National Hurricane Center (NHC) said.
The storm has brought “four months of rain in four hours” to the city, Pensacola fire chief Ginny Cranor said.
