As you can see with the last photo, there were some reports of hail near Helotes Tuesday evening. A storm briefly flared up, dropping some small hail. In addition, a 59 mph wind gust was reported at Joint Base San Antonio-Randolph. Minor street flooding was also reported. However, this was mostly a good rain event for the area, including over the Edwards Aquifer Recharge Zone. As of 10 a.m., the Edwards Aquifer was up 0.6′ and on the rise.

Heavy rain has pushed aquifer levels up and they will continue to rise. (Copyright 2021 by KSAT - All rights reserved.)

We aren’t done with the rain just yet. Another round of rain may head our way Thursday night and Friday. With the soils now saturated, flooding could become a concern during that time frame. We’ll keep you updated!
