Winter Warnings Predict 20 Inches of Snow and 45 mph Winds, Storm Kits Advised for Travel

The National Weather Service has issued a winter storm watch in two states in the U.S. this week amid falling temperatues and increasingly hazardous conditions.

The winter storms are centralized in the Pacific Northwest, with areas of Oregon and Washington facing the most extreme conditions.

Winter Storms in Oregon & Washington: 'Travel May Be Difficult'

In Oregon, the winter storm advisory will be in place from Tuesday, April 14, to Wednesday, April 15, as temperatures continue to fall and wind speeds rise throughout the region. The storm will generally affect areas above 5000ft in the High South Central Cascades in Klamath and Douglas Counties.

Total snow accumulations could reach anywhere between 4 and 15 inches in Oregon, with wind gusts reaching 45 mph in "high and exposed terrain".

The NWS warns: "Travel may be difficult with delays in your commute. The hazardous conditions could impact Wednesday morning travel."

The snowfall will primarily take place on Tuesday night, with the effects continuing into the early hours of Wednesday. "Roads, and especially bridges and overpasses, will likely become slick and hazardous," the warning states.

In Washington, snowfall will be lower at a maximum of 10 inches—though winds could still reach upwards of 45 mph. These speeds are generally considered dangerous due to their ability to uproot trees and disrupt vehicles.

"Periods of moderate and heavy snow will combine with low visibilities to create difficult driving conditions," the NWS warns.

"Persons should delay all travel if possible. If travel is absolutely necessary, drive with extreme caution and be prepared for sudden changes in visibility. 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 NWS also advises bringing a winter storm kit for any necessary travel, which should include tire chains, booster cables, a flashlight, a shovel, blankets and extra clothing. Water and first aid kits should also be stored "in case you become stranded."
