LONG BEACH — “It is probably the most powerful April storm to approach the Northwest coast during the past half century,” is how University of Washington meteorology Prof. Cliff Mass describes the strong cyclone churning up the Oregon and Washington coast today.

Examining satellite images, Mass said the storm’s form is “classic for a powerful, rapidly intensifying cyclone.”

Atmospheric pressure already is plunging around offshore weather buoys in the Pacific off southern Oregon. Buoy 46002 recorded a 25 hPa drop in six hours, eliciting a “Wow” from Mass.

“There will be substantial power outages along the coast with downed trees and associated damage,” Mass said.

He noted “The latest model forecasts are in and the forecasts are impressive. And I should note that virtually all modeling systems are providing a similar solution. Thus confidence is high.”

A high-wind warning remains in effect from the National Weather Service in Portland, currently set to expire at 5 p.m.
