What: Flash flooding caused by excessive rainfall continues to be possible.
Where: A portion of west central Texas, including the following counties, Brown, Coke, Coleman, Concho, Kimble, Mason, McCulloch, Menard, Runnels, San Saba, Schleicher and Tom Green.
When: Through Monday evening.
Impacts: Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas. Low-water crossings may be flooded.
Additional Details: - Scattered showers and thunderstorms are expected to redevelop before sunrise Monday morning across the Hill Country and then spread into the Heartland, Concho Valley, and Northern Edwards Plateau during the day. Very heavy rainfall will be possible under these downpours, with totals of 1 to 3 inches possible in many locations. A few areas may see totals in excess of 5 inches. With soils already saturated, this rain will quickly run off into creeks and streams and allow flash flooding to develop very quickly. - http://www.weather.gov/safety/flood
