Rainfall Amounts This Week

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!

Tropical Update 12AM CT: An area over the western Gulf hugging the TX coast has an increased 60% chance of tropical development within the next 48 hours. Regardless of tropical cyclone formation, our messaging remains the same; periods of intense rainfall through Tuesday 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!

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.
