...DRY AND BREEZY CONDITIONS ON FRIDAY WILL LEAD TO NEAR CRITICAL
FIRE WEATHER CONDITIONS IN THE EASTERN PORTLAND/VANCOUVER METRO,
COLUMBIA RIVER GORGE AND ADJACENT RIDGETOPS...
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.
