Harrison County has been under a flash-flood watch Saturday night until 7 a.m. Sunday because of heavy rain overnight, emergency management director Rupert Lacy said.
In addition, a disturbance in the Caribbean Sea has an 80 percent chance of developing into a tropical storm system that could hit the Mississippi Coast, forecasters say.
The National Hurricane Center reported a low-pressure area accompanied by thunderstorm activity is forming in the Caribbean. As it moves northeast across the central and eastern Gulf of Mexico, there's an 80 percent chance the low will develop into a tropical cyclone in the next four days, according to the center.
The tropical system could lead to heavy rains and flooding along the Coast early this week.
A Hurricane Hunters aircraft is scheduled to investigate the system Sunday, if necessary.
The potential for a tropical cyclone formation will end at 2 p.m. Thursday, the center said.
