PORTLAND (AP) — A weekend of stormy weather is due on Oregon’s coast with wind speeds rising to what the National Weather Service describes as hurricane force and approaching 100 mph.

The high winds are expected all along the coast Sunday and Monday. Even as far inland as Lakeview in south-central Oregon, winds could reach 70 mph in gusts, the weather service said.

Winds described as potentially of hurricane force are new for Oregon. Forecasters say the storm is not really a hurricane, but the language reflects a decision in 2002 to highlight storms that happen once or twice a decade.

Rain and snow are expected inland in the Willamette Valley, along with “significant snow” in the Columbia Gorge. The moisture could trigger flooding and travel could be hazardous, forecasters said.

The snowfall is expected to total 4 to 6 inches in the gorge on Saturday, the forecasters said, and then turn to rain. Snow is expected in the Willamette Valley, although significant accumulations are not expected.

Meanwhile, in Washington state, residents are being warned the state could be hit with some strong storms over the next few days.

State Route 20, the North Cascades Highway, was closed at 7 p.m. Friday between the Diablo Dam and Mazama because of a forecast for destructive winds. State transportation officials say the winds could reach 80 to 100 miles an hour.

The National Weather Service also says there’s a good chance of snow Saturday afternoon and evening across Western Washington,. Snowfall predictions range from 2 to 4 inches north of Everett to a trace to 2 inches around Seattle. Officials in Seattle say road crews are being prepared for snow removal if necessary.

A stronger system is expected to hit the coast Sunday.
