Update: Tornado warning canceled, severe thunderstorm watch continue until 7 p.m.

The National Weather Service has canceled a tornado warning for Hancock, Harrison and Pearl River counties but a severe thunderstorm watch for the three coastal counties continues until 7 p.m.

A front moving through central Louisiana on Saturday could bring more heavy rains for South Mississippi. One to 3 inches of rain is possible Saturday evening, which could further swell rivers and creeks already pushing their banks, meteorologists said.

The front comes just days after heavy rains caused flash flooding in several areas along the Coast, including parts of Hancock, Harrison and Jackson counties.

"The line of storms is moving faster than anticipated and it should be into the area around 4 p.m.," meteorologist Alec Krautmann with the NWS in Slidell said. "There is the potential for heavy rains with this front."

"This could bring some gusty winds and we can't rule out a tornado, but it's not a primary concern," he said.

He said the Gulf Coast is not under a flash-flood watch at this time.

"There is the potential for some heavy rains, so this is a concern, but right now we don't think flooding will be an issue," he said.

Harrison County Emergency Management Director Rupert Lacy said Saturday the rivers affected by Thursday's flooding have crested.

The Biloxi River, which has a flood stage of 12 fleet, crested at 14 feet and is receding, he said. The Wolf River has a flood stage of 8 feet and it crested Saturday morning at 8.5 feet.
