KEY POINTS
- The risk of excessive rainfall has been increased from slight to moderate
- Flash flood warnings and flood watches are up in six states, including Oklahoma
- Forecasters also warned that tornadoes are possible amid the thunderstorms
A series of severe thunderstorms is projected to hit the southern Plains Wednesday, the National Weather Service (NWS) warned late Tuesday, adding that episodes of heavy rain are also expected to bring flash flooding concerns across the south-central U.S. through early Thursday.
Aside from severe thunderstorms, there is also a possibility for tornadoes and damaging wind gusts through Thursday across parts of Oklahoma, Arkansas, and Texas.
“Numerous instances of flash flooding are possible, some of which could be potentially significant,” the agency wrote on its latest short range forecast.
Rainfall Risk Hiked
Earlier Tuesday, the NWS set the risk of excessive rainfall for the southern Plans and the Mississippi Valley to slight and marginal, but later in the day, it was increased to “moderate,” which means that there is now at least 40% risk of excessive rainfall in the affected areas.
The greatest risk is projected to affect the Red River into western Arizona, where up to several inches of rain are possible.
