Unseasonal Snow and Frost Warnings Across Five Western U.S. States
US · Published Jun 12, 2026
A rare cold snap is bringing snow, frost, and freezing temperatures to parts of the western United States, prompting the National Weather Service (NWS) to issue multiple advisories.
The affected states include Idaho, Montana, Oregon, California, and Nevada.

Why It's Important?

The cold weather poses risks to sensitive crops, outdoor vegetation, and unprotected plants, particularly in areas where frost is expected. Outdoor plumbing systems in colder pockets may also be at risk of damage. In higher elevations, snow could create slippery roads and reduced visibility, impacting travel through mountain passes like the Beartooth Highway. These conditions are particularly disruptive during the growing season and the start of the summer tourist period. Residents and travelers in the affected areas should prepare for potential hazards.
