Special Weather Statement issued August 22 at 1:26AM PDT by NWS Portland OR

1 week 4 days ago
Breezy easterly winds are expected through Friday night for the Columbia River Gorge and adjacent Cascade ridgetops and late Friday morning through Friday evening for the eastern Portland/Vancouver metro. Winds will be strongest on exposed ridgetops where wind gusts will most likely peak between 25-35 mph. Elsewhere, expect wind gusts between 15-20 mph, except up to 30 mph in the western Columbia River Gorge. The breezy east winds will occur simultaneously with low relative humidity values of 20-30% or less, resulting in near critical fire weather conditions. Due to recent rains in the area, larger fuels (such as trees and shrubs) are not dry enough to cause rapid fire spread, but the hot weather will allow fine fuels (such as grasses) to dry out quickly, allowing for potential rapid spread. Use extra caution with potential ignition sources, especially in grassy areas. Outdoor burning is not recommended.
