The National Weather Service issued a dense-fog advisory Monday, October 26, for parts of northern New Mexico, including the Santa Fe metropolitan area, warning that visibility below half a mile would make driving hazardous.
The advisory was issued at 6:37 a.m. Mountain and runs until 10 a.m. Mountain Monday. It covers the Española Valley, the far northwest highlands including Dulce, the Tusas Mountains including Chama, the northeast highlands including Las Vegas, and Union County including Clayton.
The Albuquerque office identified Interstate 25 from La Bajada Hill northeastward through Santa Fe among the affected routes. It also named the Santa Fe Relief Route, U.S. Highway 285 northward through Española and I-25 in the Las Vegas area.
The notice concerns reduced visibility during Monday morning travel. Its stated expiration is the advisory’s scheduled ending time, rather than confirmation that fog will disappear everywhere at that moment.
