Mid-South flooding: Arkansas and Mississippi could get more excessive rainfall


“No sugar coating the short term forecast,” said the National Weather Service (NWS) office in Little Rock, Arkansas.

The highest risk for excessive rainfall is forecast for the second day in a row. Then another round of rain is likely Thursday before a drying trend kicks in Friday.

“Rainfall and flash flooding will continue to be a major concern, following an extreme day of rainfall across the southeast Delta region,” the NWS said of the Wednesday forecast.

The purple shows where the most rain has already fallen across Arkansas and Mississippi. This same area is at risk for similar amounts Wednesday.

Another 2 to 5 inches of rain is forecast Wednesday for parts of eastern Arkansas and northern Mississippi, where the ground is already saturated. And more rainfall could mean flash flooding.

Flash flood watches and warnings are already in effect for the region, with potential river flooding as well.

“The greatest concern is expected to be across southeastern Arkansas and northern Mississippi, where a High Risk of excessive rainfall is in effect for Wednesday and Wednesday night,” said the Weather Prediction Center (WPC).

“This region has been hammered by torrential rain and flooding over the past 1 to 2 days, and the additional 2 to 4 inch rainfall totals on saturated ground will greatly increase the flash flood threat,” the WPC said.

Rainfall accumulations of 8 to 10 inches were seen Tuesday across the region, and some areas may have gotten more. Some parts of Arkansas have estimated a foot of rain over the last few days, and flash flooding has been significant.

Rowher, just west of the Mississippi River, got more than 9 inches of rain, giving it the rainiest June day of anywhere in Arkansas since 1959.
