A storm system moving east across the Gulf Coast was forecast to reach South Mississippi by early Friday morning, bringing heavy rains and a threat of severe weather.
Organized, severe storms are not expected to be widespread, the National Weather Service predicts, but some could affect the Coast.
Overnight, severe storms blew through South Mississippi, bringing wind, rain, thunder, lightning and tornado warnings.
The Harrison County Emergency Management Agency said possible effects include wind gusts up to 60 mph, small hail and tornadoes.
There is a 90 percent chance of rain for most of the day, with as much as 4 inches of rain possible in spots.
The Biloxi and Wolf rivers fell below flood stage Thursday, but additional rain could bring levels back up.
The good news is the rain should clear out by Saturday afternoon, leaving a partly cloudy day and a sunny Sunday.
Temperatures should remain steady with highs in the mid-80s and overnight lows in the mid-60s.
