Urgent Warning Issued as New Mexico Dam Nears Failure Amid Intense Storm

The National Weather Service has issued an urgent flash flood warning for New Mexico, stating that the McLeod Dam is in immediate danger of failing due to intense rainfall from the remnants of Hurricane Polo. Residents in low-lying areas between Garfield and Salem, and those near Highways 187 and 390, have been warned to seek higher ground immediately.

The alert, in effect until at least 6:45 p.m. ET on Tuesday, emphasizes the critical nature of the situation, with the dam's operator cautioning about potentially life-threatening flash floods if the structure gives way.

"This is a particularly dangerous situation. Seek high ground now!" NWS officials stated. They also advised drivers to avoid flooded roads, recalling that "most flood deaths occur in vehicles."

An evacuation center has been established at the Radium Springs Community Center in Las Cruces, New Mexico, approximately 60 miles from the potential danger zone.

Meteorologists predict extreme rainfall and flash flooding will continue through Wednesday night across much of New Mexico as Hurricane Polo's core moves across the border. Some areas could experience the most dangerous flash flooding risk in the last five years or more, according to AccuWeather Chief Meteorologist Jon Porter.

Beyond New Mexico, widespread flash flood warnings are in effect for southern Arizona and New Mexico, with roads in the Phoenix area already closed due to flooding. Flood watches have been issued in ten states as the effects of Hurricane Polo merge with moisture from Hurricane Odalys and a dip in the jet stream, creating a broad storm system.

This "triple flood threat" is expected to bring the heaviest rain to Arizona, Colorado, New Mexico, Kansas, Oklahoma, and Texas on Tuesday, with the storm's impact continuing through Friday. Flood watches extend to Utah, Nebraska, Missouri, and Iowa, and predictions suggest over two inches of rain could reach Arkansas, Illinois, Indiana, Michigan, and Wisconsin by Friday. Isolated areas could potentially see up to 18 inches of rain.
