Storm warnings blanket the West

Much of the Pacific Northwest and northern Rockies started the week under winter storm watches and warnings, as snow is expected to fall on Monday and move towards the Midwest and Northeast by midweek.

With the exception of Hawaii, much of the U.S. got a break from winter weather over the weekend with higher temperatures and blue skies. But those clear skies will be replaced with winter weather once again this week, as AccuWeather says “a major outbreak of Arctic air” is in store for the West. Overall, 26 states are expected to see snowfall by Wednesday, according to the National Weather Service.

“The combination of heavy snow and gusty winds will likely result in widespread hazardous travel and cause impacts to infrastructure,” the weather service said. “Record lows and dangerous wind chills possible.”

Here’s what to know:

Winter storm warnings in Pacific Northwest, Rockies

Much of the Pacific Northwest and northern Rockies was under a winter storm warning or a winter storm watch Monday morning, as some areas began to see snowfall Sunday night. In many areas, the advisories were in place until Wednesday or Thursday.

A winter storm warning, which is more severe than a winter storm advisory or watch, was issued in parts of the following states:

● Washington.

● Oregon.

● California.

● Nevada.

● Idaho.

● Utah.

● Wyoming.

● Montana.

● Nebraska.

Nearly all of Washington, Oregon, Idaho, Montana and Wyoming were forecast to see either snow or rain. Here’s the outlook for those states:

● The mountains in Washington are expected to see “significant snow,” as the entire state is forecast to have temperatures hovering in the 40s during the day and below freezing at night.

● Mountain passes in Oregon are predicted to see heavy snow.

● All of Idaho and western Wyoming forecast to see snow.

● Throughout Montana, roads are expected to hazardous with wind gusts up to 50 miles per hour. The Swan Range, Flathead Range and Southern Glacier Park in the state are also on avalanche warnings.

“Temperature readings can drop quickly, likely falling between 20-40 degrees over 24 hours for most locations,” said AccuWeather Meteorologist Brandon Buckingham.

By Monday night, North Dakota, South Dakota, Utah and Colorado were expected to see snow.

Strong winds may cause outages

The weather service said in addition to the snow, wind gusts in the West and later in the Midwest may result in blizzard conditions, increasing the risk of power outages.

“Confidence is high that this winter storm will be extremely disruptive to travel, livestock and recreation areas,” the weather service said.
