At least 14 people were killed after a tornado slammed into the USA state of Alabama and destroyed numerous homes with a death toll that could rise as rescuers sift through the rubble.
Selma, Alabama, where crowds had gathered to mark the anniversary of "Bloody Sunday", the 1965 civil rights march incident, suffered thunderstorms, Norman said, but no tornadoes.
That same storm later tracked into Georgia, leading to Tornado Warnings and damage in Muscogee and Harris counties. Strong tornadoes, damaging winds up to 70 miles per hour and quarter-sized hail are possible.
The NWS says that they will be organizing multiple survey teams to begin surveying tornado damage across north Florida, southeast Alabama, and southwest Georgia.
"Colder air will sweep into the Southeast behind the severe weather with temperatures dropping into the 30s (1 C) southward to central Georgia and across most of Alabama by Monday morning", AccuWeather meteorologist Kristina Pydynowski said.
Several people have been taken to hospitals, "some of them with very serious injuries", he added.
Early damage reports from the storm includes downed trees and limbs, standing water in roadways, according to tweets from the Lexington County Sheriff's Department.More news: Tensions escalate after Pakistan violates Indian airspace

Authorities said a tornado was confirmed by radar in the Florida Panhandle late Sunday afternoon.
"There's a squall line moving through the area", Harrigan told AP.

Alabama Governor Kay Ivey posted on Twitter to warn residents there could be more extreme weather to come. The tornado watch also covers a large area of SC, including the cities of Charleston and Columbia.
