A line of strong thunderstorms began moving through the coastal counties about 2:30 p.m., part of the same springtime storm system causing damage across the Southeast.
Cities in Hancock, Harrison and Jackson counties were affected, the National Weather Service in Slidell warned.
A severe thunderstorm watch was issued early Wednesday for Hancock and Pearl River counties until 3 p.m. There was a slight risk of severe weather Wednesday, which drops to a marginal risk Thursday.
The main threats remain large hail and damaging wind gusts. The threat of tornadoes is low.
Thursday has a 50 percent chance of rain, with isolated storms possible through Saturday. Friday is predicted to stay mostly dry and partly cloudy, with rain chances increasing to 20 percent Saturday and 40 percent Saturday night.
Sunday will likely be another wet day, with a 50 percent chance of rain and strong storms possible.
The storm system had wreaked havoc across Texas and Oklahoma on Tuesday, with six unconfirmed reports of tornadoes and more than 250 hail reports to the weather service’s Storm Prediction Center.
Wednesday’s unsettled weather comes on the five-year anniversary of a tornado outbreak that killed more than 300 people in the South, mostly near Tuscaloosa, Ala.
