Flood Watch issued for San Antonio until Thursday evening | Weather Impact Alert

SAN ANTONIO — IMPACT DAYS: Wednesday, June 11 and Thursday, June 12

Reason: Heavy rain is possible with localized flooding, severe thunderstorms with hail up to the size of quarters and wind gusts up to 60 mph.

Two weeks after San Antonio’s wettest stretch of the year, storm clouds are gathering and letting loose over the region once again. 

The stage is set for multiple rounds of showers and storms to sweep through South Texas through Thursday, bringing potentially damaging wind gusts and hail to the area, according to the National Weather Service. Thunder rumbled over the Alamo City early Wednesday morning, and parts of town saw between half an inch and eight-tenths of an inch of rain.

Now an even stronger round of rain is approaching Wednesday evening, and a Flood Watch is in effect for San Antonio and counties along the Interstate 35 corridor until 7 p.m. Thursday. According to the National Weather Service, rainfall amounts of 2 to 4 inches are expected over the next 24 hours, with isolated amounts of 6 inches possible in some areas. 

A Flood Watch means there’s potential for flooding due to incoming storms and heavy rain. 

Wednesday: Low 76, high 90. Morning showers likely for the Wednesday morning commute, with rain chances lingering through the afternoon. Storm chances return in the late afternoon; mostly cloudy all day. 60% chance of rain. 

Thursday: Low 74, high 93 degrees. Slight chance of morning showers, with storm chances returning in the afternoon, including a potential for heavy rainfall. 60% chance of rain.
