* IMPACTS...There is a potential for life threatening flooding somewhere in the watch area. Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks. Flooding may occur in poor drainage and urban areas. Low-water crossings may be flooded. Extensive street flooding and flooding of creeks and rivers are possible.

* ADDITIONAL DETAILS... - An active period of weather is forecast for South Central Texas through at least Thursday evening as tropical moisture interacts with slow-moving upper level disturbance and outflow boundaries. This combination could lead to heavy rain and flooding. Storm totals of 2 to 6 inches are possible over the Flood Watch area. Isolated amounts of 10 to 15 inches are possible across the Rio Grande Plains, southern Edwards Plateau and western Hill Country. - http://www.weather.gov/safety/flood
