A widespread flood watch has been issued across much of Texas and Oklahoma, including major metropolitan areas such as Dallas-Fort Worth, Austin, San Antonio, and Oklahoma City, through Sunday evening and into Monday morning. The western half of Texas, from the Panhandle to the Hill Country, is expected to receive multiple rounds of heavy rain and strong storms, with rainfall totals ranging from 3 to 5 inches and isolated areas potentially exceeding 8 inches. The I-35 corridor from the Oklahoma border down to San Antonio is also under flood watch, encompassing cities like Waco, Temple, Belton, Georgetown, San Marcos, and New Braunfels. Oklahoma City has experienced considerable flash flooding, with 3 to 5 inches of rain already fallen, resulting in flooded roads, stranded vehicles, and emergency road closures. Hillcrest Park in Yukon, Oklahoma, was reported completely underwater. The National Weather Service and local meteorologists have warned of a heightened risk of flash flooding, especially where soils are saturated. While some areas may remain dry, the threat of damaging winds and occasional large hail exists in parts of Texas, although no tornado threat is expected. Residents in flood-prone areas are urged to remain vigilant and avoid driving through flooded roadways.
