Flood Threat to Persist in South, Return to Ohio Valley

Round after round of drenching rain will continue to cause flooding in the South through the weekend, while another dose of rain may renew flooding in the Ohio Valley this weekend.

Heavy rain has been a frequent visitor to portions of the Deep South and the Ohio Valley this spring. The rainfall has caused dozens of incidents of flash and urban flooding.

The risk to lives and property will continue well into the weekend.

In some cases during April alone, more than a month's worth of rain has fallen in a few days.

Daily Deluge to Threaten Flooding Along Gulf Coast

According to Meteorologist Becky Elliot, "There is the potential for general 1-2 inches of rain over the central Gulf Coast states both Thursday and Friday."

Locally higher amounts are likely.

The area from Houston to New Orleans and Tallahassee, Florida, along Interstate 10 will be at greatest risk for flooding through the end of the week.

The rain forecast to fall on already saturated ground is more than enough to cause rapid rises on streams, bayous and low-lying areas.

People should anticipate travel delays due to flooded roadways and detours, as well as blinding downpours and lower speeds needed to negotiate the slick pavement.

"During the weekend, the heavy rain will shift slowly eastward and northward," Elliot said.

Enough rain will fall on portions of northern Florida, Georgia and the Carolinas to bring the potential for flash flooding. The bulk of the rain is likely to avoid South Florida.

People this weekend around Atlanta; Charlotte, North Carolina; Charleston, South Carolina; Savannah, Georgia; and Jacksonville, Florida, may want to consider altering their outdoor plans. Rounds of downpours will cause disruptions to activities ranging from baseball to golf.

Flooding Rain to Return to Ohio Valley

Farther north over the Ohio Valley, spotty rainfall through Thursday could still be enough to cause minor flooding problems, since the ground is saturated. Rainfall will immediately run off.

Areas of the Ohio Valley, centered on Kentucky, will have a stretch of dry weather or limited rainfall Thursday night into Saturday. While the gap in drenching rain will allow some small streams to recede, most waterways will continue to run high.

The next batch of heavy rain will swing northeastward from later Saturday into Sunday with another round of flash, urban and stream flooding possible.

The storm system this weekend has the potential to bring another 1-2 inches of rain over the Ohio Valley and 2-3 inches of rain, on average, in the Southeast. Even higher amounts will be possible in some areas of the South.

Remember never to attempt to drive through flooded roadways. The road may have been washed out beneath. Approximately a foot of water can cause your vehicle to drift into deeper water.

Driving through flooded areas puts not only yourself and the occupants of your vehicle but also your would-be rescuers at risk.

During episodes of heavy rain, slow down to reduce the risk of hydroplaning or pull a safe distance off the road and put your emergency flashers on.
