Overview
- Dangerous, life‑threatening flash flooding is ongoing west of San Antonio and near Hondo, with the Weather Prediction Center and local NWS offices reporting severe impacts overnight into Wednesday morning.
- Radar and MRMS data show extreme rainfall rates of about 2 to 4+ inches per hour and forecasters say localized bands could add an additional 3 to 6+ inches in a few hours in some spots.
- A Moderate Risk (Level 3 of 4) for excessive rainfall covers parts of south‑central Texas and multiple Flash Flood Warnings and Flood Watches remain in effect through midweek.
- Urban areas, low‑water crossings, campgrounds, dry washes, slot canyons and burn scars are at highest risk because saturated soils and high runoff rates can turn brief downpours into rapid, life‑threatening flooding.
- Forecasters expect repeated rounds of slow‑moving storms to continue through midweek with the threat gradually easing as the stalled front weakens, while separate heavy‑rain risks persist across the Gulf Coast, ArkLaMiss corridor and monsoon‑affected Arizona.
