The National Weather Service in El Paso keeps a flood watch in effect for El Paso and Hudspeth counties plus six counties in southern New Mexico through late Tuesday night as moisture from decaying Tropical Cyclone Polo moves north into the Borderland. Forecasters warn that repeated rounds of rain up to 4 inches on already saturated ground may cause flash flooding, and a separate wind advisory takes hold Tuesday afternoon.
Travelers passing through the El Paso region Monday night through Wednesday morning should delay nonessential driving, avoid low water crossings and add buffer to airport plans. Drivers who had mapped the mountain route should check the Scenic Drive route guide before heading up, especially since the overlook road closed both ways on September 23 and the ground around it is soaked.
- Watch window: Flood watch runs through late Tuesday night, September 30, for El Paso and Hudspeth counties and nearby New Mexico counties.
- Cause: Tropical moisture ahead of decaying Tropical Cyclone Polo brings repeated storms with up to 4 inches of rain.
- Highest risk hours: Rain chances reach 65 percent between 6 p.m. and midnight Monday, with a second round by noon Tuesday.
- Wind add-on: A wind advisory runs noon Tuesday to 9 a.m. Wednesday with gusts to 55 mph.
- Free sandbags: City and county sites plus a Socorro location are distributing bags with per household limits.
Polo Moisture Sets a Two Round Rain Schedule
The weather service says tropical moisture streaming north ahead of Polo will fuel widespread showers and thunderstorms across the watch area Monday and Tuesday. High rainfall rates and repeated downpours are the core concern because last week brought about 1.90 inches of rain to El Paso, saturating soils and leaving arroyos and low lying streets with little room to absorb more, according to the National Weather Service El Paso flood watch statement.
Timing matters for anyone on the road. The El Paso Times reports Monday daytime rain chances near 5 percent, jumping to 65 percent between 6 p.m. and midnight, followed by a second round of storms by noon Tuesday as Polo remnants push through, per the El Paso Times sandbag and rainfall update. That overnight and midday cadence means both Monday evening drives and Tuesday morning commutes face ponding, reduced visibility and possible street closures.
Forecasters single out rivers, creeks, streams and low water crossings as the first places to flood. The weather service urges residents in flood prone spots to monitor later forecasts and be ready to act if warnings replace the watch. A flash flood warning already fired Monday afternoon for parts of Dona Ana and Sierra counties in New Mexico, where radar indicated an inch of rain near the highway toward Spaceport America, showing how fast isolated storms are turning wet roads dangerous.
Sandbag Sites Open Before the Heaviest Rain
El Paso city crews are handing out sandbags at Blackie Chesher Park at 1100 N. Zaragoza Road in the Lower Valley from noon to 8 p.m., with a limit of 10 bags per visit, valid identification required and residents asked to load their own bags. The Stormwater Operations Center on Fred Wilson Avenue and the Artcraft Road location have closed, so travelers staying in flood prone rentals should not waste a trip to those addresses.
El Paso County offers free sandbags around the clock at Road and Bridge warehouse pallets in Fabens, Canutillo and Montana Vista, limited to five bags per household, and rural residents can report flooding to county public works at 915-273-3330. In Socorro, free bags are available at the Rio Vista Center at 901 N. Rio Vista Road, open 24 hours while supplies last, with proof of residency and a 10 bag household limit.
The limits and ID rules mean a traveler cannot stock a whole block or a commercial property on a courtesy stop. Hotel guests rarely need sandbags, but visitors in ground floor vacation rentals near arroyos or drainage channels should ask hosts whether the property already has protection staged before the Monday night round arrives.
Road, Air and Tuesday Wind Risks for Travelers
Drivers should treat every flooded dip and arroyo crossing as a turn around point. Most flood deaths happen in vehicles, and desert roadways can hide washed out pavement under shallow looking water. Night driving compounds the risk because ponding and debris are harder to see between the Monday evening and Tuesday midday storm rounds.
Air travelers using El Paso International Airport should build extra buffer Monday night and Tuesday rather than cutting connections close. Thunderstorms can trigger ground stops and slow ramp crews even when the terminal stays dry, and flooded access roads can make a normally short ride to the airport run long. Rental car drivers headed to White Sands, Las Cruces or Marfa should check conditions along US 70, I-10 and I-25 before departure since the watch covers the full corridor.
Tuesday adds wind to the hazard mix. The weather service advisory warns of southwest winds of 20 to 30 mph gusting to 55 mph from noon Tuesday to 9 a.m. Wednesday across parts of southern New Mexico and southwest Texas, including the El Paso area. High profile vehicles, empty trailers and rooftop cargo face difficult handling, and gusts can scatter unsecured objects and knock down limbs, with a few power outages possible.
| If you… | What to do |
|---|---|
| Drive through El Paso Monday night | Leave before 6 p.m. or wait until Tuesday morning and check road reports first. |
| Stay in a ground floor rental near an arroyo | Ask the host about sandbags and drainage, and know high ground options. |
| Fly out of El Paso Tuesday | Add at least an extra hour and watch airline alerts for ground delays. |
| Tow a trailer or drive a high profile vehicle Tuesday | Delay until after the wind advisory ends Wednesday at 9 a.m. |
Monday 6 p.m. to midnight is the first gate. Rain chances jump to 65 percent, so finish essential driving before evening or stay put.
Tuesday noon is the second gate. Polo remnants bring another storm round, so keep Tuesday morning flexible and recheck forecasts.
Wednesday 6 a.m. is the watch exit. The flood watch ends and soils begin to drain, though low spots may still hold water.
Is El Paso under a flood warning or a watch?
El Paso County is under a flood watch through late Tuesday night, September 30, which means flooding is possible. A separate flash flood warning covered parts of New Mexico on Monday afternoon, and watches can be upgraded if storms stall.
When will the heaviest rain reach El Paso?
The heaviest windows are Monday between 6 p.m. and midnight and again by noon Tuesday as Polo remnant moisture moves through, with up to 4 inches possible in repeated rounds on saturated ground.
Where can visitors get sandbags in El Paso?
City residents can collect up to 10 bags at Blackie Chesher Park from noon to 8 p.m. with ID, county rural residents can take five bags at 24 hour warehouse pallets, and Socorro residents can use the 24 hour Rio Vista Center while supplies last.
Should travelers change Tuesday driving plans?
Yes for exposed routes. The noon Tuesday to Wednesday morning wind advisory brings 55 mph gusts that make high profile vehicles hard to handle, on top of lingering flood risk at low water crossings.
