Heavy rains are expected to continue though Saturday and could increase flood threats in areas that are already saturated with several inches of water.
Flash flooding of roads, low-lying and poor drainage areas will be possible. The National Weather Service wants to remind motorists who encounter flash flooding while driving their vehicle "to turn around, don't drown." More flood deaths occur in vehicles than anywhere else, according to NWS.
Firefighters in Broken Bow, Okla., performed a floodwater rescue early Wednesday.
Two men were out overnight when they drove in a creek on Currence Road northeast of Broken Bow, said Fire Chief Ryan Martin.
Martin said the men were driving around late at night when their vehicle went into the creek and stalled out.
The men were in the creek for several hours until daybreak when one walked out for help.
"They were hanging onto trees waiting for daylight. They didn't have a way to call for help," Martin said.
Rescues workers then helped the other man out of the water. Water was over the top of the men's SUV when firefighters reached them.
"At least nobody got hurt," Martin said.
Since heavy rains started Tuesday, Broken Bow has received almost 4 inches of rain Wednesday afternoon with more in isolated areas.
Parts of Sevier and Little River counties in Southwest Arkansas had also received about 4 inches.
The Office of Emergency Management reported the Little River is expected to crest at 24 feet with flooding at 21 feet.
Anyone with cattle in the Little River bottoms near Horatio is encouraged to move them out.
A flash-flood warning was issued Wednesday morning for much of the area. A flash-flood watch remained in effect through 6 a.m. this morning.
Texarkana received about 3.5 inches of rain by late Wednesday.
According to the NWS, the flood threat may increase over these areas tonight and Friday before diminishing late in the day as the front begins to lift north out of the area. However, the parent upper level trough and associated cold front will quickly move through the region, which may result in a renewed threat for heavy rainfall and flash flooding, along with the threat for strong to severe thunderstorms, which will progress east across the region Saturday afternoon and evening. The severe and heavy rainfall threat will diminish from west to east Saturday evening.
