If you have outdoor plans for New Year’s Eve, you may want to grab a raincoat or even postpone them. Rain is moving into South Mississippi and, according to the National Weather Service in New Orleans, and it’s going to be abundant.

“There’s a lot of rain moving into the Mississippi Gulf Coast — that’s the gist of the situation,” meteorologist Alek Krautmann said. “Light rain is already moving in from the west and the heavier stuff should be there around 3 p.m.”

On Saturday morning, the NWS issued a flood warning for the Biloxi River near Lyman and the Tchoutacabouffa above D’Iberville. The warning was issued because of forecast rainfall over the next 24 hours.

At 8:45 a.m., the Biloxi River near Lyman was at 1.2 feet. Flood stage is 12 feet. The forecast calls for the river to rise near flood stage by early Sunday. At 9 feet, the river will be bankfull at Three Rivers Road Bridge, the NWS said.

At 9:30 a.m., the Tchoutacabouffa at D’Iberville, whose flood stage is 8 feet, was at 0.4 feet. The warning is for Sunday evening to Monday morning. The river is expected to rise above 8 feet late Monday night and continue rising until it crests about 12 feet overnight Monday and into Tuesday morning.

At flood stage, property along Lamey Bridge Road will be inundated and water will be at the undercarriage of the bridge.

Rupert Lacy, the emergency management director for Harrison County, updated the forecast and anticipated effects.

He said 3 to 6 inches of rain is expected in South Mississippi, with more possible in isolated areas.

Residents can expect ponding in low-lying areas and wherever drainage is poor. Some flooding also is possible in addition to the flood warnings issued by the National Weather Service earlier Saturday.

Lacy also said the main severe-weather issues Monday will be high winds and possibly isolated tornadoes.

Krautmann said the rain is going to be heavy at times and accumulations could reach 6 inches.

“There’s not a significant chance for severe weather, but there is a chance for isolated thunderstorms,” he said.

The chance of rain for New Year’s Eve is 100 percent.
