Yet more rain is expected through Thursday in the south-central US, setting up moderate risks of further flooding in central Texas, southern Louisiana and parts of southern Oklahoma and Arkansas. More than 31 million people were under flash flood watches Tuesday morning, largely in those four states.
More than 250 people have been evacuated and brought to higher ground in East Baton Rouge Parish, and no injuries have been reported, parish fire department spokesperson Curt Monte told CNN Tuesday morning.
“We have buses running to carry those who have nowhere to go to the airport, where we have a reception center set up to assess their needs,” Monte said.
More than 50 roadways in East Baton Rouge Parish were impassable early Tuesday, and emergency crews received more than 160 calls for help, parish spokesperson Mark Armstrong told CNN.
Numerous stranded cars were reported in the parish, the National Weather Service’s office in New Orleans said.
Sheriff’s deputies guided boats across floodwater covering streets, fields and yards, reaching homes and helping surrounded residents get to dry ground, video from KBTV showed.
Flood warnings also were in effect Tuesday morning for the Port Arthur and Beaumont areas of southeastern Texas, as well as southwestern Louisiana including Lake Charles — one of the areas hardest hit by Monday’s rain.
Lake Charles floods as it rebuilds from 2 hurricanes
Lake Charles, a city of about 75,000 people, got some of the worst of Monday’s rain — more than 12 inches fell, including about 6 inches in two hours.
“We just can’t catch a break,” Dick Gremillion, Calcasieu Parish’s homeland security director, told CNN. “It remains to be seen, but we still see a lot of blue roofs around where people have not replaced their roofs, so a heavy rain event like this is devastating for those people who haven’t gotten their roofs repaired yet.”
For Lake Charles resident Derek Williams, the water rose so quickly Monday that it only took 45 minutes for a car parked on the street to be submerged. It was the car of a neighbor’s friend, who was safe, he told CNN.
“The only time it’s flooded like this in the last little while was during Hurricane Delta,” Williams said. “And even then it took all day to get this high.”
“It last flooded for Hurricane Delta late last year,” he told CNN. “The rain started around 4 a.m. When the water started getting high, I ran outside to reuse some of the sandbags I had from those hurricanes.”
The sheriff’s office in Calcasieu Parish, which includes Lake Charles, urged residents to stay off the roads because of flooding threats. “Roadways and conditions are deteriorating and changing quickly,” the office said in a Facebook post.
Gov. John Bel Edwards declared a state of emergency because of the flooding in the state Monday night, authorizing the use of state resources to help with response efforts.
More than 100 calls for rescue in Lake Charles
More than 100 rescue calls were made in Lake Charles on Monday, Gremillion said.
“We have people stranded around the area who are stuck in high water,” he said. “They’re not necessarily in any danger, but they can’t get from where they are to home, or to work, or wherever they’re trying to get to.”
Most of the calls are believed to be welfare checks to evacuate residents, but earlier in the day, at the height of the rainfall, rescuers helped people from vehicles that ventured too far into the water, Gremillion said.
Nearly half the roads in the parish were under some water, Gremillion said. “We have floodwaters in places that we’ve never seen flooding before,” he said.
Monday brought the city’s third-highest rainfall total on record. The highest on record was 15.79 inches, on June 19, 1947. Second highest was 15.67 inches, on May 16, 1980.
Extreme rainfall closely linked with the climate crisis
This is leading to more 1-in-5-, 1-in-10-, 1-in-100-year-type extreme rainfall events that lead to catastrophic flash flooding.
These trends are consistent, according to scientists, with what is expected in a warming world, as warmer temperatures cause more evaporation which leads to higher levels of water vapor in the atmosphere, which can in turn lead to more frequent and more intense rainfall.
