A triple weather threat headed towards Louisiana is expected to bring heavy rain, possible strong storms on Thursday and coastal flooding until Saturday morning.
A slow-moving weather system will make its way through the state this week and will bring between 4 and 7 inches of rain to south Louisiana with some areas facing the possibility of getting several inches more, according to the National Weather Service.
“The biggest threat right now is heavy rain,” said Robert Rickey, meteorologist with the National Weather Service office in Slidell.
The forecast is about the same from Lafayette, Baton Rouge and New Orleans with heavy rain continuing throughout the rest of the week. The timing would have the heavy rain hitting Lafayette starting Tuesday evening and reaching Baton Rouge Wednesday evening as the front slowly pushes through the state.
The heavy rain could bring the chance of flash floods in low-lying areas while a south wind will help push water onshore in coastal areas raising tides by a foot or two.
Heavy rains could dump more water into rivers and streams, but around south Louisiana water levels have been falling so there is room to accommodate at least some of the additional rainfall. Water on some rivers could reach minor flood levels.
Storms on Thursday could bring heavy winds, hail and isolated tornadoes, Rickey said.
Rainfall will likely continue through Friday before tapering off Saturday.
“We’re going to have a beautiful day Sunday,” Rickey said.
