EUGENE, Ore. -- An overnight storm knocked down trees and power lines across the state, and forecasters say more gusty weather is on the way.
The National Weather Service issued a high wind advisory for much of the Willamette Valley that is in effect until 10 p.m. Saturday. They predict heavy gusts with rain squalls that could cause more tree damage and spotty power outages. | Current Weather Forecast
A warm front is expected to bring heavy rain to the Valley on Sunday, followed by dryer weather across Northwest Oregon and Southwest Washington by Monday night.
Eugene Water and Electric Board spokesman Joe Harwood said their crews have been working on scattered power outages across the city. Many were localized faults caused by branches laying on power lines, however they reported 600 people lost power near 25th Ave. and Maddison when a line was knocked down.
"This is the first big storm of the season, and with the sustained winds you get a lot of dead and dying tree limbs falling down, creating faults and knocking out power for our customers," Harwood said.
Currently EWEb is reporting scattered outages along the McKenzie Highway for customers east of the Leaburg Power Plant to Thompson Lane.
Officials said winds could reach 55 to 65 mph at the North Coast Saturday, with the potential for 40 mph or higher winds inland. Viewers reported lightning storms in the central Willamette Valley near Corvallis.
Forecasters say colder air moving in will dump heavy snow in the Cascades, with as one to two feet possible at higher elevations. Strong winds may cause snow to blow and drift.
U.S. Highway 20 was closed near Sweet Home for several hours Saturday morning as crews cleared downed power lines.

A wind advisory is issued when sustained winds are forecast to be 31 to 39 mph or gusts will range between 45 and 57 mph. Winds of these magnitudes may cause minor property damage without extra precautions. Motorists in high profile vehicles should use caution until the winds subside.
"You've heard the term "poisonous tail" of the bent back occlusion, but have you seen it? This Satellite image from 10 a.m. Friday shows the classic frontal structure of a well developed pacific front. The occluded front wraps back around the low and is well depicted not only in the infrared satellite imagery, but to some degree in the Weather Prediction Center plotted surface analysis. You can really make out the tail extending from the south and west side of the Low pressure area marked with the "L". This area features strong winds well behind the main cold front, and this feature will move over parts of the area later today. This will bring another surge of gusty to strong winds. So expect a brief lull in the winds this morning before they pick back up considerably later this morning. Additionally, expect plenty of showers with small hail, and even a clap of thunder may be possible." - NWS Portland
