Table of Contents

Just when you thought spring was here to stay, Mother Nature has other plans. A massive late-season winter storm is currently gearing up to slam several western states, bringing heavy snow and howling winds with it.

According to the National Weather Service (NWS), winter storm warnings and weather advisories are in full effect. Travelers and outdoor enthusiasts should brace themselves for some seriously hazardous conditions.

Which States Are in the Line of Fire?

This powerful weather system is spreading its icy grip across a massive chunk of the American West. The main areas facing heavy accumulations include Wyoming, Utah, Montana, Washington, and Oregon.

Whether you are planning a weekend mountain getaway or just heading out for your daily commute, this storm is bound to disrupt your plans. Expect rapidly changing conditions as you move from sunny valleys to high-elevation passes.

Wyoming Braces for the Worst of the Storm

If you are in Wyoming, you might want to stay indoors if possible. The state is expected to bear the brunt of this late-season onslaught, particularly in central and northern regions.

  • Wind River Mountains East: Bracing for a whopping 8 to 16 inches of snow, paired with terrifying wind gusts up to 50 mph.
  • Green Mountains and Rattlesnake Range: Expecting 6 to 14 inches of fresh powder.
  • Natrona County (including Casper): Anticipating 3 to 5 inches, with local areas seeing up to 7 inches.

With wind gusts reaching up to 50 mph, blowing snow will create dangerous whiteout conditions. Driving in these areas will feel like navigating inside a giant snow globe, so extreme caution is advised.

Snow Forecasts Across Other Western States

Wyoming isn't the only state getting a winter makeover. Significant snowfall is also headed to neighboring regions.

In Utah, the Western Uinta Mountains could see anywhere from 6 to 14 inches of heavy snow. Meanwhile, Montana's Rocky Mountain Front is preparing for up to 12 inches of accumulation in higher terrains.

Further west, the Cascades in Washington and Oregon are expecting a lighter dusting, with 1 to 6 inches forecast above 4,000 feet. However, don't let those lower numbers fool you; mountain roads will still be incredibly slick.

Hazardous Travel: Passes and Highways to Avoid

Planning a road trip through the mountains? You might want to delay your travel plans if they involve any high-elevation routes.

Slippery roads and near-zero visibility will make driving treacherous, especially across bridges and mountain passes. Key routes expected to experience major disruptions include Interstate 80 in Sweetwater County, Wyoming, and Highway 14 through the Bighorn Mountains.

Over in Montana, high-altitude passes like Homestake, Rogers, and MacDonald Passes are also on high alert. If you absolutely must drive, check out this Ready.gov car safety guide to ensure your vehicle is fully prepared.

How to Stay Safe During This Late-Season Blast

Safety should be your absolute top priority over the next few days. If you must venture out onto the roads, make sure your trunk is stocked with essential winter gear.

Always carry a sturdy snow shovel, a reliable flashlight, warm blankets, and plenty of non-perishable food and water. Additionally, backcountry travelers should be wary of extreme wind chills, which can rapidly increase the risk of hypothermia.
