FORECAST HIGHLIGHTS

HOT DAYS AHEAD: Upper-90s likely, triple digits possible by Wednesday

NUECES & FRIO FLOODING: Cotulla and Tilden will experience major flooding soon

TD #2/POTENTIALLY BERTHA: Disorganized for now, some strengthening possible. Odds currently favor minimal/no impacts for South Texas

AQUIFER/LAKES STILL RISING: Aquifer tops 650′ for the first times since 2022

FORECAST

FIRST TRIPLE DIGITS OF THE YEAR FOR SA?

We’ve managed to avoid triple digits this year. This week, however, it may be hard to dodge a late-July heat wave. Temperatures will rise, with peak temperatures on Wednesday. As of now, we are forecasting 100° in San Antonio. Heat indices will reach the low-100s.

TROPICAL DEPRESSION #2

A tropical system has formed in the Gulf. Some strengthening is expected today and it could receive a name: Bertha. While there is still a good deal of uncertainty with TD #2’s future, we are getting a bit more clarity this morning. TD#2/Bertha likely affects the New Orleans area tomorrow into Wednesday. From there, it will encounter more wind shear, dry air, and possibly interact with land, with several computer models weakening the system. It then makes a run at South Texas during the second half of the work week. However, at the time it arrives to Texas, it very well could be in a weakened state. That means impacts to San Antonio and surrounding areas would be minimal. That said, as it is with tropical systems, much can change over the next 48 hours. Stay tuned for more updates.

COTULLA/TILDEN

While it has yet to flood along the Nueces and the Frio near Cotulla and Tilden, floodwaters will rise soon. These locations need to be on high alert through the weekend.

AQUIFER/LAKES STILL RISING!

While our bodies of water are starting to level out, we’re still noticing small rises in area lakes and the aquifer. Canyon Lake is now 99% full, while Medina has reached 27% capacity. The Edwards Aquifer at the J-17 well is now above 650′ for the first time in more than 4 years!
