Downpours to aggravate recovery efforts in flood-ravaged Louisiana through Monday

Topic driven playlist

Thunderstorms will increase in coverage and threaten to exacerbate the flooding situation across Louisiana through Monday.

"A front will stall out near the Gulf Coast, leading to a couple of unsettled days across the region," according to AccuWeather Senior Meteorologist Frank Strait.

The enhanced rainfall will only add insult to injury across flood-ravaged Louisiana.

"The ongoing downpours will not only hinder rescue, recovery and cleanup efforts but could also lead to additional incidents of flooding," according to AccuWeather Senior Meteorologist Alex Sosnowski.

During the third week of August, Louisiana endured what the Red Cross described as the "worst natural disaster to strike the United States since Superstorm Sandy."

An area of low pressure crawled along the Gulf Coast states, dumping over 30 inches of rain in parts of Louisiana.

"Much of this rain fell during a two-day period and has a 0.1 percent chance of occurring, which translates to a 1,000-year rainfall event," Sosnowski said.

At least 13 people have died in the flooding, 40,000 homes have been damaged and 30,000 people have been rescued since Friday, Louisiana Gov. John Bel Edwards stated.

While the rainfall over the next few days will not be nearly as significant as what fell this past week, it will not take much additional rainfall to cause more flooding problems.

"Any additional rain is unwanted there right now," Strait said.

Those who are outside helping with clean-up efforts should be mindful of the threat for storms each day and seek shelter at the first rumble of thunder or stroke of lightning.

In addition to aggravating the ongoing flooding situation in Louisiana, slow-moving downpours could spell flooding trouble for some communities farther west in central and southern Texas, including San Antonio and Austin.

Drenching storms prompted numerous road closures and water rescues in the suburbs of San Antonio and Austin on Saturday night.

While bringing the threat for flooding, the downpours will also drastically reduce visibilities and slow motorists along portions of interstates 10, 35, 45 and 49.

As downpours lessen in central and southern Texas beyond Monday, spotty, but locally drenching storms will continue in southern Louisiana.
