Overview
- NWS advisories that went up Sunday warn of heavy, late-season snow across high terrain in Colorado, Wyoming and Montana.
- Most mountain spots are forecast for about 3 to 12 inches, with fresh Monday guidance calling for 6 to 10 inches in Wyoming’s Sierra Madre and Snowy Ranges and isolated peaks like Battle Pass and Grand Mesa near 24 inches.
- Gusts up to 45 mph will whip up blowing snow, cutting visibility and making backcountry travel risky for hikers, hunters and snowmobilers.
- Road impacts include slick, low-visibility stretches on I-25 and I-90 near Buffalo in Wyoming, Powder River and Granite Passes, Marias Pass in Montana, and several Colorado passes.
- The storm began over California on Saturday, is tracking toward the Upper Midwest with rain for parts of Northern California and Nevada, and forecasts point to lighter snow chances before a warmer, drier weekend.
