At least two people died and more than 100 were injured in Alabama after severe thunderstorms pounded the South and Midwest early Monday, leaving thousands without power and prompting tornado warnings in a handful of states. 

Authorities identified the dead as a 16-year-old girl from Clay, Ala., and an 82-year-old man who lived in the community of Oak Grove.

A storm system produced a possible tornado that moved across northern Jefferson County around 3:30 a.m., causing damage in Oak Grove, Graysville, Fultondale, Centerpoint, Clay and Trussville, Christian said. He said several homes were destroyed and numerous injuries were reported. 

Power outages were also reported for tens of thousands of people, Fox affiliate WBRC-TV reported.  

"Some roads are impassable, there are a number of county roads where you have either debris down, trees down, damage from homes," Yasamie Richardson, a spokeswoman for the Alabama Emergency Management Agency, told the Associated Press. Jefferson County experienced "significant damage," she said.
