SAN ANTONIO – Tropical Storm Hanna has been intensifying in the Gulf of Mexico Friday. As of 10PM Friday night, Hanna is moving west at 8 mph with maximum sustained winds of 65 mph. Hanna will move onto the Texas coast Saturday, with landfall expected south of the Corpus Christi area. At the time of landfall Saturday, Hanna could be a Category 1 hurricane.

Regardless of name and title, the impacts to San Antonio and the surrounding areas will be the same: a chance at some much-needed rainfall!

Beneficial Rainfall Possible

July has been bone-dry, with only a trace amount of rain officially recorded at San Antonio International Airport. With Stage 1 water restrictions in place, a falling aquifer level, and drought conditions creeping in, healthy rainfall would be welcome. With the approach of Tropical Storm Hanna, rain chances continue to look decent for San Antonio beginning late Saturday (7/25) and continuing into Sunday (7/26). San Antonio has a chance of seeing some scattered downpours through the weekend, which could result in up to 1″ of rain. Rainfall totals could approach 3″-5″ closer to the coast, where the center of Hanna’s circulation is likely to produce more widespread, potentially flooding rain.
