Livingston, Tangipahoa brace for flooding

DENHAM SPRINGS — Forecasters say rivers in Livingston and Tangipahoa parishes will cause backwater flooding from Thursday through Saturday.

Luckily, the backwater flooding from rainfall in Mississippi and St. Helena Parish won’t be accompanied by the flash flooding that occurred last month, said Mark Harrell, director of the Livingston Parish Office of Emergency Preparedness.

Still, police notified people in low-lying areas of Denham Springs to expect flooding Thursday from the Amite River.

Mayor Jimmy Durbin said flooding in areas affected by the Amite is expected to be slightly worse than the high water that followed heavy rains last month.

Much of the flooding is expected in areas from River Road west, including Centerville Extension, he said.

River Road probably will close Wednesday night or early Thursday morning, Police Chief Scott Jones said.

Officers talked to people in neighborhoods where high water is expected, but most of those people were already preparing, Jones said.

“The people know what to do,” the police chief said Wednesday. “The next 12 hours will tell us everything.”

The Amite River exceeded the flood stage of 29 feet Wednesday and had reached 29.5 feet at 4 p.m.

The river is expected to crest Thursday night or early Friday morning at 32.5 feet, according to the National Weather Service.

It crested last month at just below 32 feet, Durbin said.

The Weather Service predicts moderate flooding on the Amite River at Bayou Manchac on Friday night when the river stage is projected to reach 12.5 feet there. The flood stage at Bayou Manchac is 9 feet.

Friday night or Saturday, the Amite River at Port Vincent is projected to crest at 8 feet, which is flood stage.

Forecasters predict moderate flooding at Robert, where the Tangipahoa River should crest at 18.5 feet Thursday night. Flood stage there is 15 feet.

They predict minor flooding on the Tickfaw at Montpelier and Holden.

The Tickfaw at Montpelier is projected to crest Thursday evening at 13.5 feet. Flood stage is 13 feet.

The Tickfaw at Holden should crest Saturday at 16 feet, which is a foot above flood stage.
