A National Weather Service meteorologist says there are reports of "significant" damage from a possible tornado in southeast Alabama near the Georgia state line.

Meteorologist Meredith Wyatt said video and radar showed a possible tornado hitting near Smith's Station, Alabama, on Sunday afternoon. Wyatt said she had no immediate reports of serious injuries.

The National Weather Service on Sunday issued a series of tornado warnings stretching from Phenix City, Alabama, near the Georgia state line to Macon, Georgia, about 100 miles (160 kilometers) to the east.

The threat of severe weather was expected to continue until late Sunday. A tornado watch was in effect for much of Georgia, including Athens, Augusta and Savannah. The tornado watch also covers a large area of South Carolina, including the cities of Charleston and Columbia.
