In Alabama, as many as nine tornadoes were reported Sunday, including one damaging more than 200 homes in Prattville and a mobile home park in Millbrook, the Montgomery (Ala.) Advertiser reported Monday. No deaths were reported, but officials said two people were seriously injured and 25 others received cuts and bruises.

A strong super-cell thunderstorm rumbled across middle Georgia Sunday, injuring several people and causing extensive damage, the Atlanta Journal-Constitution reported. The National Weather Service said the storm "crossed a nearly 100 mile portion of central Georgia."

Between 3 and 6 inches of snow was predicted for places between north-central Oklahoma to central Ontario, AccuWeather.com reported Monday. Blustery wind in the storm could create near-whiteout conditions.

Meanwhile, a soaking rain was expected to spread over locales east of the snowstorm. Rain trying to seep into already-saturated ground and runoff into swollen rivers has raised concerns of flooding, AccuWeather.com said.

Intense thunderstorms were forecast throughout the Southeast while the soaking rain was expected to spread over the Northeast.
