Up to 24 inches feet of snow are forecast to fall across higher elevations of Glacier National Park this weekend.

A Winter Storm Warning is in effect for areas in West and East Glacier through Sunday at noon. Snow totals could potentially reach a foot or more above 5,000 feet between Saturday and Sunday morning. Around 4,000 feet to 6,000 feet — which includes Logan Pass and Going to the Sun Road, snow totals may be between 3" to 6".

Backcountry travelers in Glacier National Park in Montana this weekend should be prepared for wintry conditions, as a rare summer snowstorm could dump a foot or more of snow on the park's highcountry.

A combination of rain and snow could also trigger rock slides and trigger power outages and downed trees. The NWS warns against unnecessary travel for this area. In the West Glacier Region, the winter storm warning applies from 2 a.m. MDT on Saturday to noon on Sunday.

As summer officially kicks off, many Americans are dusting off their swimsuits and planning outdoor excursions. However, a rare and formidable weather phenomenon is poised to disrupt those plans, bringing an unseasonal winter storm that could dump up to two feet of snow in parts of the country.
