The National Weather Service in Austin/San Antonio has issued a

* Flash Flood Warning for...
Central Williamson County in south central Texas...

* Until 1015 AM CDT.

thunderstorms producing heavy rain across the warned area. Between
1 and 3 inches of rain have fallen. Additional rainfall amounts of
1 to 3 inches are possible in the warned area. Flash flooding is
ongoing or expected to begin shortly.

HAZARD...Life threatening flash flooding. Thunderstorms
producing flash flooding.

SOURCE...Radar and automated gauges.

IMPACT...Life threatening flash flooding of creeks and streams,
urban areas, highways, streets and underpasses.

* Some locations that will experience flash flooding include...
Round Rock, Georgetown, Taylor, Serenada, Leander, Hutto, Liberty
Hill, Jarrell, Florence, Thrall, Weir, Georgetown Dam, Sun City,
Andice, Coupland, Jonah, Walburg, Theon, Waterloo and Seward

</description><instruction>Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Be especially cautious at night when it is harder to recognize the
dangers of flooding.

Be aware of your surroundings and do not drive on flooded roads.

In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to cross flooded
roads. Find an alternate route.

Please report observed flooding to local emergency services or law
enforcement and request they pass this information to the National
Weather Service when you can do so safely.</instruction><web>http://www.weather.gov</web><parameter><valueName>AWIPSidentifier</valueName><value>FFWEWX</value></parameter><parameter><valueName>WMOidentifier</valueName><value>WGUS54 KEWX 211206</value></parameter><parameter><valueName>flashFloodDetection</valueName><value>RADAR AND GAUGE INDICATED</value></parameter><parameter><valueName>flashFloodDamageThreat</valueName><value>CONSIDERABLE</value></parameter><parameter><valueName>BLOCKCHANNEL</valueName><value>EAS</value></parameter><parameter><valueName>BLOCKCHANNEL</valueName><value>NWEM</value></parameter><parameter><valueName>EAS-ORG</valueName><value>WXR</value></parameter><parameter><valueName>VTEC</valueName><value>/O.NEW.KEWX.FF.W.0011.260421T1206Z-260421T1515Z/</value></parameter><parameter><valueName>eventEndingTime</valueName><value>2026-04-21T10:15:00-05:00</value></parameter><parameter><valueName>WEAHandling</valueName><value>Imminent Threat</value></parameter><parameter><valueName>CMAMtext</valueName><value>NWS: FLASH FLOOD WARNING this area til 10:15 AM CDT.
