Heavy Rainfall and Potential Flooding Event September 17, 2014 1300 Wednesday #1 Regions Affected 4, 5, 6 None
STATEWIDE CURRENT SITUATION: Moisture associated with Tropical Storm Odile (or its remnants) will bring a threat of locally heavy rainfall to portions of Texas through the weekend. The greatest threat of flash flooding today and Thursday exists in extreme West Texas where a Flash Flood Watch is in effect through Thursday. The main threat area will shift northeastward by Friday and into the weekend, with some threat of locally heavy rainfall or isolated flash flooding across the Texas Panhandle. Across Central Texas, scattered showers and thunderstorms could produce locally heavy rainfall resulting in very isolated flash flooding concerns. NWS Southern Region Headquarters has provided the following geographical breakdown of forecast rainfall amounts, expected impacts, and areas of concern. West Texas: A Flash Flood Watch is in effect through Thursday for areas highlighted on the map below. Rainfall amounts of 2 to 4 inches are likely over southern New Mexico and extreme West Texas, with some locally higher amounts. Area mountains could see 5+ inches of rainfall. Potential Impacts: Normally dry arroyos, streams, and river beds could be filled quickly with fast-moving water, mud and debris. Low-water crossings likely will become impassible. Flooding of homes and businesses in low-lying and flood-prone areas will be possible. Some flooding could be life-threatening. (See following graphic.)
