The Brief

Authorites in Missouri said 10 people were killed and multiple people were injured after a string of violent tornadoes and severe weather.

The weather service said at least five tornadoes were reported in Missouri on Friday, including one in the Saint Louis area. Several buildings were damaged.

The Storm Prediction Center warned that fast-moving storms would spawn twisters and hail as large as baseballs, but the greatest threat would come from straight-line winds near or exceeding hurricane force, with gusts of 100 mph (160 kph) possible.

"Potentially violent" tornadoes were expected Saturday in parts of the central Gulf Coast and Deep South into the Tennessee Valley, according to the National Weather Service.

The Storm Prediction Center said parts of Mississippi including Jackson and Hattiesburg and areas of Alabama including Birmingham and Tuscaloosa would be at a high risk. Severe storms and tornadoes were also possible across eastern Louisiana, western Georgia, central Tennessee and the western Florida Panhandle.
