NORMAN, Oklahoma — A flash flood watch has been issued for much of Oklahoma as another round of heavy rainfall approaches.
The National Weather Service in Norman says heavy rainfall and possible flash flooding are possible through Wednesday evening.
Forecasters say a slow moving front will move into northern and central Oklahoma Monday evening. The front combined with warm, moist air will enhance shower and thunderstorm development as well as the possibility of flash flooding.
Rounds of heavy rain are forecast beginning Monday afternoon across northwestern Oklahoma. The heaviest rainfall will occur Tuesday afternoon through Wednesday across central and southwestern Oklahoma. Forecasters say the heavy rain is expected to end by Wednesday evening.
Between 2 and 5 inches of rain is likely and rainfall rates may exceed 2 inches per hour at times.
