South Central Texas Partners...(Briefing graphics are attached) ...HEADLINE... ...Flash Flood Watch is in effect for all of South Central Texas from 6 PM tonight through Noon on Wednesday... ...AREA OF CONCERN... All of South Central Texas, but the highest totals as of right now are forecast along and east of the I-35 corridor....including the Austin and San Antonio metro areas....and areas south of Highway 90. ...IMPACTS... · Flash Flood Watch in effect for all of South Central Texas for Tue 6 PM until Noon Wednesday. · Locally heavy rains of 2-4 inches, isolated totals of 7 inches. · Highest totals along and east of I-35 corridor....south of Highway 90. · High rain rates, in excess of 1-2 inches of rain per hour. · Increased flows on creeks and low water crossings with some Flash Flooding possible in both urban and rural areas. · Some roads may become impassable. · Thunderstorms with dangerous lightning and gusty winds. ...TIMING... · Heaviest rainfall is expected from 6 PM Tuesday through 8 AM Wednesday....with highest rain intensities from 8 PM Tue thru 4 AM Wednesday. ...CONFIDENCE... Moderate-High ...DISCUSSION... An approaching upper level storm system and cold front combined with increasing moisture from the Gulf of Mexico and the Eastern Pacific will lead to widespread rains across South Central Texas starting late Tuesday afternoon into Wednesday morning. A cold front will move into the Hill Country this afternoon and will help to trigger lighter rainfall during the day. As an upper level disturbance moves closer to Texas tonight, widespread heavy rains are expected to break out across much of South Central Texas during the evening and overnight hours. The slow moving cold front will be an added trigger for rainfall, while the deep moisture will help produce high rain rates. Rain totals late Tuesday afternoon through early Wednesday could reach into the 2-4 inch range, with isolated totals near 7 inches. Flash Flooding is a concern and thus we have issued a Flash Flood Watch for all of South Central Texas starting at 6 PM tonight until Noon on Wednesday. Wednesday morning will see the front and associated heavy rain start to shift east and south into the Coastal Plains of Texas, mainly along and south of a line from Carrizo Springs to San Antonio to Hallettsville. Lingering rainfall is still possible across the I-35 corridor on Wednesday but the threat for additional heavy rain will be pushing south and east. Please keep "weather aware" over the next 24 hours as forecasts and the timing of the front/upper level system are fine tuned. Most flash flood fatalities occur at night while driving. If you don't have to be out this evening through the overnight hours, stay at home. Remember...Turn Around...Don't Drown.
