Flood Watch

Flood Watch issued November 20 at 12:36AM CST until November 21 at 6:00AM CST by NWS Austin/San Antonio TX
Nov 20, 12:36 AM Nov 21, 6:00 AM
WHAT: Flooding caused by excessive rainfall continues to be
possible.

WHERE: A portion of south central Texas, including the following
counties, Bandera, Bexar, Blanco, Burnet, Comal, Edwards,
Gillespie, Hays, Kendall, Kerr, Kinney, Llano, Maverick, Medina,
Real, Travis, Uvalde, Val Verde and Williamson.

WHEN: Through late tonight.

IMPACTS: 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. 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.
