More high winds were in the mid-valley forecast Saturday, but not as strong as the gusts that downed some trees and cut power in some areas Friday.

Pacific Power spokeswoman Doris Johnston said outages in the mid-valley were minimal, but some residents in a part of North Albany and Lebanon were in the dark for a time Friday.

Pacific Power said from Portland that as of 7 p.m. Friday, about 350 customers were without power in Lebanon but were expected to be back on later in the evening. Elsewhere in Oregon the utility also was coping with storm-caused outages in Medford (about 1,300 customers); Roseburg (750) and Pendleton (300). Coos Bay, Hermiston, Grants Pass and Klamath Falls areas each had fewer than 100 outages reported, along with smaller isolated outages are spread throughout southern, central and eastern Oregon.

The University of Oregon issued a statement warning students returning from winter break to be extra careful during the predicted winter weather over the weekend. Classes resume Monday.

Pacific Power said it had anticipated the damage based on weather forecasts and was able to position crews to hasten restoration efforts. The storms were expected to intensify into this morning, continuing to affect customers. Additional storms over the weekend may affect areas already hit as well as locations on the Oregon Coast and the Willamette Valley, the utility said.

Due to the type of weather damage, power customers should expect extended outages. Many of the downed lines are individual and feeder lines affecting individual and small clusters of customers, which must repaired one by one.

The National Weather Service warned of a series of powerful winter storms. For the latest road conditions, travelers should consult the ODOT website at www.tripcheck.com.

In the valley the wind speed for Saturday was forecast between 13 and 23 miles per hour. The Corvallis Airport reported sustained 35 mph winds Friday afternoon with gusts of 47 mph.

Winds could easily be strong enough to cause some trees to fall, said Peggy Peirson, the emergency services coordinator in Benton County.

Highway 101 was closed indefinitely 10 miles north of Florence at milepost 179 at about 4:50 p.m. Friday because of a rock slide.

For the Cascadess, snow advisories were in effect until 4 p.m. Saturday. From 4 to 7 inches of snow was expected. The snow level was expected to drop to about 2,000 feet Saturday from 4,500 feet Friday evening.

Besides the wind and rain, forecasters say there could be a thunderstorm Saturday. The chance of precipitation is 90 percent.
