The National Weather Service issued an updated winter storm warning and winter weather advisory for the regions where Idaho, Montana and Wyoming border each other.

The new winter storm comes just in time for many in the region to start their preparations for the 250th birthday of the United States as millions prepare for the 4th of July. Those in the region are asked to consider delaying their travel across the backcountry this weekend and into the early portion of the week.

Persons should consider delaying travel across the backcountry and higher elevations. If travel is absolutely necessary, consider taking a winter storm kit along with you, including such items as tire chains, booster cables, flashlight, shovel, blankets and extra clothing," the National Weather Service said. "Also take water, a first aid kit, and anything else that would help you survive in case you become stranded."

3 Feet of Snow Expected to Fall

Specific regions in Montana are expected to see "heavy, wet" snow and the Georgetown Lake region could see as much as three feet of snow fall from Saturday night through Tuesday. Those in the region are warned to prepare for dangerous conditions.

"Plan for winter-like conditions in the backcountry and higher elevations. Cold temperatures, wind, and wet snow will elevate the risk of hypothermia. Heavy wet snow may down trees, blocking access to backcountry roadways," a warning from the National Weather Service read.

Coincidentally, 4th of July Peak in Idaho is expected to see around a foot of snow over the next three days. Meanwhile, Pitchstone Plateau will see the most snowfall in Wyoming with eight inches coming over the next few days.

Along the border of Montana and Wyoming near the Beartooth Mountains the snow will lighten or even stop for a time Sunday afternoon into Sunday evening. Snow will redevelop Sunday night and continue into Monday and Tuesday morning.

Snow isn't the only issue, though, as the region also braces for significant winds.

"Strong winds develop across portions of north-central MT this afternoon/evening around a low pressure center meandering around the International Border. Wind speeds are likely to peak early this evening with a few gusts in excess of 50 mph causing difficult cross-winds," the Great Falls office said.

Campers were specifically warned ahead of the storm.

"Campers should be aware that it only takes a few inches of snow to damage tents and other recreational items," a warning from the National Weather Service read.

The winter storm warnings and winter weather advisories run through Monday night.
