A flood watch is in effect through Wednesday evening for portions of central, south central and southwest Louisiana as a slow-moving front inches across the state, bringing with it rounds of showers and a few thunderstorms for at least another two days.

After 1 to 2 inches of rain fell across Acadiana overnight and throughout the day Tuesday, an average of 2 to 4 inches is expected to fall through Thursday, said Jonathan Brazzell, National Weather Service meteorologist.

“It looks like the heaviest time frame is Wednesday afternoon until night for most of the area,” he said.

Parishes under a flash flood watch through Wednesday at 7 p.m. are Acadia, Allen, Avoyelles, east portions of Cameron, Evangeline, Iberia, Jefferson Davis, Lafayette, Rapides, St. Landry, upper and lower St. Martin, St. Mary and Vermilion.

A flood watch in those same parishes is in effect through Wednesday afternoon.

Low-lying areas, underpasses and roadways with poor drainage could flood, and small streams, creeks and bayous may have rapid increases in water flow.

Rain chances will lessen but continue through Thursday, with cloudy skies and only a slight chance of rain expected Friday.

Come the weekend, temperatures will rise to the mid-70s with a few “peekaboo” sunrays possible, although clear weather isn’t forecast until Monday or Tuesday, Brazzell said.
