Isolated thunderstorms dumping 2 to 4 inches of rain can be expected across South Mississippi through Tuesday, the National Weather Service warns.
Heavy rainfall moved in Monday morning, causing flooding on the roads and prompting the National Weather Service to issue a flash flood watch through 7 p.m. Tuesday for the lower six counties.
Harrison County Emergency Management Director Rupert Lacy said in a weather alert email that amounts of up to 5 inches are possible, and some rivers could rise to near flood stage. Gusty winds and frequent lighting can also be expected with the storms, the weather service warns.
U.S. 90 between Pine and Cedar streets in Biloxi was closed about two hours Monday during a hard rain, Biloxi city spokesman Vincent Creel said.
Area law enforcement agencies were working weather-related crashes on Monday. Officials encourage motorists to turn on their headlights and drive slower than normal if they must be out in the rain.
Chance of rain was 100 percent all day Monday, the weather service predicted, falling to 60 percent Tuesday and 20 percent Wednesday and Thursday.
Temperatures are expected to stay warm, with highs in the low to mid 90s and lows in the mid 70s. But a cold front is expected to cool the Coast slightly this weekend, and could bring a chance of severe weather.
Residents should monitor the weather because the conditions can change rapidly, Lacy said.
