Monday's Storm

A classic November-December setup featuring a powerful jet stream stretching from eastern Asia across the Pacific for 5,000 miles to the Pacific Northwest will act as the conductor for this storm parade ahead. 

In fact, winds at jet-stream level over parts of the North Pacific well west of the U.S. were estimated at over 200 miles per hour Friday morning. Talk about a quick flight from Tokyo to Seattle, albeit just a wee bit choppy.

The latest round of rain, wind, and mountain snow will continue to impact Washington, Oregon, far Northern California, Idaho and western Montana into late Monday.

NOAA's National Weather Service (NWS) has issued high wind warnings that are in effect into Monday for parts of the southwest Washington and Oregon coasts. High wind warnings are also in effect for the eastern slopes of the Oregon Cascades. Wind gusts of 60-70 mph are possible at times in the above mentioned areas.

Wind advisories are in place from the Portland, Oregon, and Vancouver, Washington, areas southward into the Willamette Valley for gusts up to 45 mph on Monday.

Snow levels in the Washington Cascades will rise to 5,500-6,500 feet during the day on Monday.
