Weather situation and cause
An El Niño‑influenced system is delivering prolonged rain across the region. A Pacific jet stream positioned over Texas is pulling warm moisture from the Pacific and the Gulf, creating a sustained soaking rather than isolated thunderstorms.
Flash‑flood threat level
The National Weather Service has assigned a Level 2 excessive rainfall threat to the area. Rainfall totals of 2‑5 inches are expected in Laredo, Brush Country and the Rio Grande Plains, with isolated spots possibly reaching 6 inches. Minor to moderate flash flooding is possible, especially on low‑lying roads and at drainage‑restricted crossings.
- Level 2 indicates elevated flood risk but not guaranteed flooding at every location
- Highest concerns focus on communities south of San Antonio and near the U.S.–Mexico border
Travel impacts and safety advice
The heaviest rain is forecast for Sunday afternoon through Monday morning, creating hazardous road conditions, reduced visibility and possible standing water. Motorists are urged to avoid flooded crossings and stay alert to changing conditions. Coastal areas such as Corpus Christi may also see minor coastal flooding combined with rain‑driven runoff.
- Roads near drainage channels, rural crossings and low‑lying sections could become impassable
- Travel across the U.S.–Mexico border may be complicated by wet pavement and reduced visibility
