Gusts as high as 50 mph Wednesday afternoon and evening near the base of the Blue Mountains have prompted an advisory from the National Weather Service.
The advisory will be in effect until 11 p.m. along the foothills of the Blues and includes Pendleton, Pilot Rock, Heppner, Condon and Fossil, weather service forecasters announced.
A strong surface pressure gradient and low-level jet stream will result in very windy conditions, the statement said.
The closer to the base of the Blues, the weather service reported, the stronger the winds.
Winds near the base of the Blues will reach sustained speeds of 25-35 mph with gusts up to 50 mph. Winds will get stronger throughout the day, peaking in the afternoon and early evening.
A wind advisory also will be in effect for Wallowa County and eastern Union County, including La Grande and Elgin. Sustained winds there will reach 30-40 mph with gusts up to 55 mph.
Winds of these magnitudes can make driving difficult for some vehicles and could cause property damage, according to the statement.
