SAN ANTONIO (KTSA News) – A Flash Flood Watch remains in effect until 7 pm Saturday. The National Weather Service says chances for a tropical cyclone formation in the western Gulf of Mexico have decreased to 20 percent.
There’s a potential for tropical funnel clouds east of Highway 281, south of IH 10 today as the system moves inland. These will be short-lived and are not expected to touch down.
Forcecasters say regardless of development, the main impact from this system will be periods of heavy rain and potential flooding today through late Saturday across South Central Texas.
Rainfall amounts of 1-3 inches with isolated pockets near 5 inches are possible.
Heavy rainfall and flooding are of greatest concern for the Coastal Plains, San Antonio metro area, portions of the Hill Country, and Rio Grande Plains.
Flash flooding of low water crossings, underpasses and urban areas are possible with minor to moderate flooding likely on the Rio Grande, Nueces, Frio and San Antonio Rivers.
