Heavy rain potential this week in San Antonio with Tropical Storm Watches along Texas Coast

As we’ve been reporting, the National Hurricane Center is monitoring the Gulf of Mexico for tropical storm development. Regardless of development, the impact to San Antonio will be times of heavy rainfall Wednesday and Thursday this week. Here’s what you need to know:

KEY POINTS

  • Latest indications continue to suggest that this system would move west towards Mexico, with the higher wind impacts staying well south of our area
  • However, the area of low pressure will throw deep, tropical moisture and rain north into San Antonio and South Central Texas
  • As of now, scattered tropical downpours are forecast to develop on Wednesday and Thursday, along with cooler temperatures
  • The highest rain totals will be near the coast, but totals in the range of at least 2″-5″ are looking possible closer to San Antonio

HOW MUCH RAIN?

Please be mindful that it won’t be raining all day Wednesday and Thursday. Rather, there will be times of heavy rain. Still, this could lead to street flooding so please be cautious and check the radar before driving Wednesday and Thursday.

THE LATEST

As of Monday evening, “Potential Tropical Cyclone One” (PTC 1) was located over the Bay of Campeche and is expected to strengthen into a weak tropical storm named Alberto with winds of 45 mph by Wednesday. It is anticipated to stay relatively weak and make landfall in northeastern Mexico by Thursday morning.

If the storm were to take a more northerly track than anticipated, it would result in gusty winds and minor storm surge along Coastal Texas. As a result, Tropical Storm Watches have been issued for areas from South Padre Island to Galveston/Coastal Houston.
