Flood Watch issued as thunderstorms could ruin Labor Day plans in San Antonio

Did anybody else get randomly soaked while at a high school football game last night? Well, whether you were or not, rain was all over the San Antonio area on Saturday night, August 30, and it looks like there may be that and more on the way. 

The National Weather Service has issued a Flood Watch is in effect beginning noon on Sunday, August 31 that will last until Monday, September 1. What a way to welcome in the next month. “Rainfall totals of 2 to 4 inches can be expected with isolated totals up to 8 inches possible,” the NWS said on social media. “These rainfall amounts may lead to flash flooding.” 

On top of the forecast, the NWS also shared information about how to react to sudden flash flooding, should anyone in the area be hit unexpectedly by a wave of precipitation that hits the roads. 

A 50% chance of showers and thunderstorms will pick up after 1 p.m. in San Antonio, while the sky remains partly sunny. A high temperature of 97 will hit the area with heat indexes getting as a high as 105 degrees. And if you’re telling yourself “the wind should help, right?” wind gusts of about 5 miles per hour will blow through, so there’s a little bit of relief. 

However, things look to pick up as night falls, the NWS is reporting chances of thunderstorms picking up overnight into Monday. Winds will pick up to as high as 20 mph as a 70% of precipitation hits the area after 4 a.m. “New rainfall amounts between a tenth and quarter of an inch, except higher amounts possible in thunderstorms,” the NWS said.
