As much as 10 inches of rain soaked parts of Acadiana over the weekend, flooding roads and seeping into homes, and forecasters said Sunday there is still more rain to come.
Flash flood warnings remained in effect overnight for much of south Louisiana and the National Weather Service predicted several more inches could fall through Tuesday night.
“There may be some breaks in the rainfall, but it’s not looking good at all,” said Todd Mogged, a forecaster with the National Weather Service in Lake Charles, as he scanned maps of the region Sunday afternoon.
Mogged said just over 5 inches of rain fell on Lafayette, but areas just to the north were hit even harder. About 11 inches fell around Cankton in southern St. Landry Parish over the weekend, Mogged said.
Much of the area was already wet from rains Saturday, and forecasters said more rain is likely in store, issuing flash flood warnings through Monday evening.
The National Weather Service predicted an additional 2-4 inches could fall on Acadiana with some isolated areas receiving as much as 6 inches. Those storms Sunday night and Monday “will likely produce flooding,” the Weather Service forecast said.
St. Landry Parish Sheriff Bobby Guidroz said a family had to be rescued from their home near Cankton Sunday morning and several roads in the area could only be traveled through via boat.
Emergency responders in parishes throughout Acadiana said they were bracing for possible flooding Sunday night after spending much of the morning redirecting motorists from swamped roads.
Interstate 49 between Opelousas and Lafayette was closed much of Sunday morning. Police and government agencies rescued motorists near Sunset and Grand Coteau as well as in Lake Charles.
Gusting winds knocked down electrical poles in Crowley, KATC-TV reported, and Head Start centers in Lafayette and Arnaudville have closed because of the flooding.
The Acadia Parish Sheriff’s Office said a number of roads flooded and downed trees were blocking others.
“We’re going to be on standby all night,” said Guidroz, who added that deputies had two Army surplus high-water trucks at the ready in case residents became stranded by rising water. “What really concerns all of us is water getting into people’s homes.”
No St. Martin Parish residents needed to be rescued from the floods Sunday, said Maj. Ginny Higgins, spokeswoman for the Sheriff’s Office, but several roads were under water Sunday morning.
Higgins said deputies were closely monitoring flood-prone areas, including the area around Cecilia High School, and had sandbags available.
Flooding of homes and businesses was reported, including in Lake Charles, Carencro and Henderson. Hail fell Sunday in Lake Charles, Plaquemine, White Castle, Gonzales and areas of Lafourche Parish.
Roads were also closed because of high water in Ascension and Tangipahoa parishes. In New Orleans, the heavy rain caused headaches for organizers of the Zurich Classic golf tournament and the New Orleans Jazz and Heritage Festival.
