Flash flooding closes roads in Gallup and near Zuni Pueblo

Flash flooding sent fast-moving water across Old Gallup Road, Lakeside Drive and Sandy Springs Road in Gallup and near Zuni Pueblo, with warnings staying active until evening in McKinley County. Flooding also hit Oak Wash and surrounding low areas, putting drivers on some of the county’s most familiar routes at immediate risk.

The National Weather Service Albuquerque office showed a last map update of 12:08:04 a.m. MDT Friday, and its flash-flood products tied the storm to New Mexico’s summer monsoon pattern. The office’s 2026 monsoon outlook was updated May 21, a reminder that forecasters have been watching for this kind of rapid runoff across the region since the start of the season.

In Gallup, the road names matter because they are not abstract flood zones. Old Gallup Road, Lakeside Drive and Sandy Springs Road are all routes where water can turn a routine drive into a dangerous crossing in minutes, especially when runoff funnels into Oak Wash and nearby low ground. The flooding near Zuni Pueblo added another layer of concern for residents moving between communities in western McKinley County.

The broader weather picture in New Mexico has been volatile all summer. The National Weather Service Albuquerque’s July 2024 climate and weather summary described July 2024 as a very active month for flash flooding statewide, with five Flash Flood Emergencies and dozens of swift-water rescues. No fatalities were reported in that month, but the scale of response showed how quickly monsoon storms can overwhelm roads, arroyos and drainage channels.

Gallup has its own long record of flood danger. A U.S. Geological Survey report documents a major flood there on July 17, 1972, underscoring that the city’s flood threat is not new and that the same corridors can be exposed again when heavy rain falls over McKinley County.
