A stormy pattern will persist across the western Gulf Coast into early May, threatening to renew the risk of flooding from Texas to Mississippi through at least Monday.
"The deluge of heavy rain will continue across the Gulf Coast as a slow-moving front drags eastward," according to AccuWeather Meteorologist Brett Rossio.
Locations from eastern Texas to Louisiana and Mississippi will contend with multiple days of heavy rain and storms, which will enhance the risk for flash flooding.
"A moist, southerly flow from the Gulf of Mexico will converge with this front and ignite several rounds of heavy showers and thunderstorms along the Gulf Coast states into Monday night," he added.
Cities that are at risk for flash flooding early this week include Beaumont, Houston and Galveston, Texas; Baton Rouge, Lafayette, Lake Charles and New Orleans, Louisiana; and Biloxi and Jackson, Mississippi. Residents of neighboring communities should also not let their guard down.
The drenching rain and storms will train over areas that were hit hard by deadly flooding a few weeks ago.
Houston and New Orleans both received more than double their normal rainfall for the month of April.
Even a couple inches of rain in as many hours could cause flash flooding due to the saturated ground and high water levels in rivers, streams and bayous.
Numerous rivers in southeastern Texas and southwestern Louisiana remain at or above flood stage. Any additional rainfall will cause water to quickly spill onto neighboring roads and lands.
"The flooding situation will only be exacerbated," Rossio warned.
Motorists are urged to turn around and find an alternate route if a flooded roadway is encountered. The water may be deeper than it appears and the roadway underneath could be compromised.
As is typical in springtime, any storms that erupt could quickly turn severe, adding an additional hazard to the area. Damaging winds and large hail will be the primary threats, but an isolated tornado or two could spin up.
A much-needed dry spell will return to the region by the middle of the week.
"High pressure will finally push the frontal boundary out of eastern Texas by Monday night," Rossio stated. "Drier air will push into New Orleans by Tuesday night."
The drier conditions and increasing amounts of sunshine will allow rivers and streams to gradually recede and the ground to begin to dry out.
The area of high pressure will keep rain away from the region into at least the early part of Mother's Day weekend.
