Heavy Snow Warning for 6 States as 30 Inches of Snow, 100 mph Winds Approach: 'Delay All Travel'

Spring might officially have started, but there are still several states in the path of heavy snow this week. At least six states are expected to see at least a foot of snow starting on Wednesday, April 1 – and no, this isn't an April Fool's Day joke.

The National Weather Service's latest forecast shows California, Colorado, Nevada, Oregon, Utah and Wyoming are all expected to see 12 inches of snow or more in the coming days.

"A surface cyclone will cross inland into Washington/Oregon on Wednesday, and will then become conglomerated with the frontal system in the Northern Rockies," the National Weather Service said. "This is expected to bring precipitation in the Rockies and Pacific Northwest in the form of rain, and wintry mix in regions of higher elevation."

"Heavy mountain snow is also expected as the fronts move through. On Thursday, the associated cold front is forecast to move through the Northwest and Great Basin, bringing in cooler temperatures and more widespread snowfall, as opposed to snowfall confined to higher elevations."

Up to 30 Inches of Snow, 100 mph Winds Coming for 6 States

California: Regions near Blue Canyon are expected to see the highest snowfall with total snow accumulations five to 12 inches near the crest, including Donner Pass. Locally higher accumulations over peaks are expected with winds gusting as high as 55 mph.

Colorado: Cities of Skyway, Aspen, Snowmass, Vail, Vail Pass, Minturn, Crested Butte, Taylor Park, Marble, Monarch Pass, and McClure Pass are expected to see between six and 12 inches, with locally higher amounts possible. Winds gusting as high as 40 mph are in the forecast.

Nevada: Snow accumulations of six to 12 inches above 8,000 ft, with locally up to 14 inches. Near Lake Tahoe winds are expected to reach up to 100 mph bringing strong waves as high as six feet.

Oregon: The heaviest snowfall is expected to hit in Oregon with 24 to 30 inches in Crater Lake National Park. Winds gusting as high as 50 mph over high and exposed terrain are possible. Meanwhile, Toketee Falls, Union Creek, Diamond Lake, and Crescent Lake are also expected to see heavy snow with 18 to 24 inches possible.

Utah: For the northern mountains, total snow accumulations up to three to seven inches, with upwards of eight to 14 inches in the upper Cottonwood Canyons. Meanwhile, for the central and southern mountains, total snow accumulations of 8 to 16 inches, with upwards of 18 inches in the Tushar Mountains and Brian Head area.

Wyoming: High elevation snow expected with total snow accumulations between 6 and 12 inches mainly above 9,000 feet in elevation. Winds are forecast to gust as high as 45 mph.

Travel Warning Issued by National Weather Service

The National Weather Service included a special warning for Oregon as it prepares for several feet of snow.

"Persons should delay all travel if possible. If travel is absolutely necessary, drive with extreme caution and be prepared for sudden changes in visibility," the warning reads. "Leave plenty of room between you and the motorist ahead of you, and allow extra time to reach your destination. Avoid sudden braking or acceleration, and be especially cautious on hills or when making turns. Make sure your car is winterized and in good working order."

The heaviest snowfall in Oregon is expected from Wednesday morning through Thursday morning.
