Today

Tonight

A Flood Watch is in effect for South Texas through Thursday morning. The combination of a moist tropical airmass, a stalling front, daily seabreeze circulations, and a broad area of low pressure over northeastern Mexico will result in heavy rain. Isolated pockets with rain totals of 8 inches or more are possible with rain rates of 2-4 inches per hour and up to 5"/hr. at times. If you come across a flooded road, remember: Turn Around, Don't Drown!

Be extra cautious this week as heavy rainfall could cause flooding issues. Don't drive into flood waters, be safe!

The National Hurricane Center has highlighted an area over the western Gulf with 50% chance of development in the next 7 days. Regardless of tropical cyclone formation, our messaging remains the same; periods of intense rainfall over the next several days could produce widespread flooding. Gusty winds and coastal flooding are also possible.

A tropical plume of moisture will continue to keep chances of rain through mid-week, with Monday and Tuesday having a Moderate Risk (level 3 of 4) and Wednesday with a Marginal to Slight Risk (level 1 to 2 of 4) for flash flooding. Remember: Turn Around, Don't Drown!

Expect a wet and rainy day. We are under a Moderate Risk (level 3 of 4) for excessive rainfall and potential flash flooding. Cloudy skies and expected precipitation will help keep afternoon highs in the mid 80s today. If encountering flood waters, Remember to turn around, don't drown.

Mostly cloudy skies will accompany lows in the mid- to upper 70s tonight. Accompanied by a continued moderate chance for excessive rainfall and flash flooding across much of the region.
