A flash flood watch remains in effect until midnight for the same areas. The National Weather Service alert states residents can expect periods of moderate to heavy rainfall with storms repeatedly moving over the same areas that recently received nearly 4-8 inches of rain.
"Rapid water runoff due to the nearly saturated soils and high water levels for area rivers, creeks and bayous" can lead to flash flooding on roads and in low-lying and poor-drainage areas, the NWS alert warns.
Drivers are urged to turn around and find another route when approaching flooded areas.
