Heavy rain and severe thunderstorms capable of producing tornadoes, damaging wind gusts and hail are likely across the eastern Gulf Coast—including portions of southern Georgia, Alabama and Florida—and into North and South Carolina, where a severe thunderstorm warning is in effect, the National Weather Service said.

A strong storm system threatened to whip up tornadoes in parts of the U.S. Southeast on Sunday, a day after severe weather claimed at least two lives as twisters touched down in Texas and Mississippi.
