The thunderstorm that blew through San Angelo late Tuesday and into Wednesday morning dropped 1.12 inches of rain to the gauge at Mathis Field and there’s more rain in the forecast.
National Weather Service Meteorologist Mark Cunningham said rains are expected to subside briefly during the day Wednesday, increasing into the evening hours. A 70 percent chance of heavy rains remains in the forecast for Wednesday. Wednesday night, chances for heavy rains continue at 60 percent.
“This morning probably won’t be too bad, and then during the afternoon and evening, the showers and thunderstorms are going to pick up again,” Cunningham said. “With these storms, there’s a potential for locally heavy rainfall and potential for flash flooding.”
A flash flood watch is in effect for the Concho Valley through 7 a.m. Thursday.
High rainfall amounts will cause flooding of low water crossings and other flood prone areas. Creeks and streams will quickly fill with swiftly moving flood waters. Drivers should use caution through low water crossings in the area.
A flash flood watch means that conditions could develop that lead to flash flooding. Flash flooding is a dangerous situation, according to the NWS. Drivers should monitor later forecasts and be prepared to take action in the event that flash flood warnings be issued.

Jackson Street from Knickerbocker Road to South Bryant Boulevard
