One of the worst-hit areas since Wednesday has been northwestern Arkansas, where local airports recorded 2.25 to 3 inches of precipitation in their rain gauges. Bentonville saw some of the worst flash flooding, leaving people stranded in the high water. Several state highways in the region were still closed as of Thursday morning due to high water or washouts, according to the Arkansas Department of Transportation.
A slow-moving frontal system is moving through the region, resulting in “training” — the same areas being hit by the torrential rain over and over again. Drainage systems can’t keep up, and waterways rise quickly.
