Overview
- A Flood Watch issued Sunday night remains in effect through 7 p.m. Tuesday and covers the San Antonio metro area plus large parts of South‑Central Texas, including the Hill Country and the I‑35 corridor.
- Forecasters say repeated rounds of slow‑moving showers and thunderstorms are likely, with the greatest concern for the heaviest storms coming Monday night into Tuesday.
- Widespread rainfall totals of 1 to 3 inches are expected but some spots could pick up 6 to 8 inches or more where storms train over the same area, and the strongest storms may drop 2 to 3 inches of rain per hour.
- The National Weather Service warns there is potential for life‑threatening flooding somewhere in the watch area and urges residents to monitor official updates and never drive through flooded roadways.
- Rainfall should taper Tuesday evening with conditions improving Wednesday, though weather models note a weak frontal system later in the week that could bring additional localized storms and renewed flood risk.
