Football fans heading to Norman and Stillwater today will get wet.
"Ponchos would be a necessity,” said Ty Judd, National Weather Service meteorologist.
A flash-flood watch has been issued for central, east-central, southwest, western, northern and northwest Oklahoma, including Norman and Stillwater, until tonight. Rainfall of 2 to 3 inches is expected, with some areas receiving 5 to 8 inches as the remnants of Henriette blow through.
Judd said fans should leave early and avoid flooded streets.
"We're already saturated, so it's not really going to take a lot to flood,” Judd said.
Umbrellas are prohibited at Gaylord Family — Oklahoma Memorial Stadium in Norman and Boone Pickens Stadium in Stillwater.
