While the most extreme rainfall has fallen west of San Antonio, parts of Bexar County have still experienced remarkable rainfall totals during this week’s historic flood event.
The highest verified storm total was measured 5.8 miles south-southeast of Boerne, where 13.90 inches of rain has fallen since the event began. Several locations across the Interstate 10 corridor, Fair Oaks Ranch, and Cross Mountain have received 10 inches or more, while much of northern Bexar County has picked up between 8 and 10 inches.
Even downtown San Antonio has recorded more than 9 inches of rain, highlighting just how widespread this event has been across the county.
Although the widespread heavy rain is expected to diminish, flooding concerns are not over. Runoff from the Hill Country will continue feeding area rivers and creeks, and water levels may continue rising long after the rain ends. Residents should remain cautious around low-water crossings, flooded roadways, and waterways that remain above normal.
