The National Weather Service is advising residents of El Paso and portions of southern New Mexico to prepare for periods of heavy rain and the possibility of isolated flash flooding beginning Thursday evening and continuing into the weekend.
Timing and areas of greatest concern
Forecasters say the first round of thunderstorms could produce up to 1 inch of rain across the El Paso region between 1 p.m. and 8 p.m. MT on Thursday, July 16, along with frequent lightning. Storm chances will remain elevated during evening hours from Friday through Sunday (July 17–19), with the threat of flash flooding increasing farther west toward Lordsburg in southern New Mexico.
| Period | Location | Forecast |
|---|---|---|
| Thu, July 16, 1–8 p.m. MT | El Paso area | Up to 1 inch rain; frequent lightning; isolated flash flooding |
| Fri–Sun, July 17–19 (evenings) | El Paso and southern NM | Increasing evening rain chances; higher flash-flood risk westward |
Why flash floods can happen quickly
Flash flooding commonly occurs when intense thunderstorms drop large amounts of rain in a short time or when slow-moving storms repeatedly cross the same area. In urban zones, impervious surfaces such as concrete and asphalt prevent absorption, allowing runoff to rise rapidly in streets and drainage channels.
Safety guidance
- Stay informed: Monitor local media and NOAA Weather Radio for updates.
- Avoid flood waters: Never drive or walk through moving water — just a few inches can sweep vehicles or people away.
- Move to higher ground: If you are in a low-lying or flood-prone area, relocate immediately.
- Follow evacuation orders: If authorities direct you to leave, do so without delay; secure your home if time allows.
- Electrical safety: Do not enter rooms where outlets or cords are submerged; if you observe sparking or unusual noises, exit and keep clear.
Storms capable of producing rapid rises in creeks and urban drainage systems are possible through the weekend. Residents should review personal emergency plans and avoid unnecessary travel during heavy downpours.
Warmer, drier conditions are expected to return next week, according to the National Weather Service.
