* WHEN...Through late tonight.
* IMPACTS...Excessive runoff may result in flooding of rivers,

Creeks and streams may rise out of their banks. Flooding may occur
in poor drainage and urban areas. Low-water crossings may be
flooded. We urge people to stay weather aware and keep up with
weather updates from us and trusted sources.
* ADDITIONAL DETAILS...
- An upper level storm system and above normal atmospheric
moisture will combine to create several rounds of rainfall
overnight through late tonight. Rainfall amounts of 1 to 3
inches with isolated totals of 6 to 8 inches are possible.
The focus for the highest rainfall amounts is likely to
remain across the western Hill Country and southern Edwards
Plateau, where the Weather Prediction Center highlights those
areas under a moderate risk of rainfall exceeding flash flood
guidance.
