FIRE WEATHER PLANNING FORECAST FOR NE OREGON AND SE WASHINGTON
NATIONAL WEATHER SERVICE PENDLETON OR
548 AM PDT MON JUN 22 2026
DISCUSSION
ELEVATED FIRE WEATHER CONCERNS CONTINUE WITH DRY
CONDITIONS WITH MINIMUM RELATIVE HUMIDITIES LINGERING OVER THE
NEXT FEW DAYS RANGING FROM 10 TO 21 PERCENT. LOCALLY BREEZY WINDS
MAY DEVELOP BRINGING ISOLATED AREAS OF CRITICAL FIRE WEATHER
CONDITIONS IN-PLAY BUT COVERAGE AT THIS TIME DOESN'T WARRANT A
RFW.
***THUNDERSTORMS IMPLY STRONG GUSTY WINDS ***
***WINDS ARE 20 FOOT 10 MINUTE AVERAGES ***
***CWR: CHANCE OF WETTING RAIN 0.10 OR GREATER ***
***VENTILATION INDEX IS DERIVED FROM TRANSPORT WIND
MULTIPLIED BY THE MIXING HEIGHT IN 100'S OF FT.
CATEGORIES ARE A GENERALIZED INDICATOR AND USERS
ARE ENCOURAGE TO DEVELOP CRITERIA THAT ARE
SUITABLE AND REPRESENTATIVE OF DISPERSION
CONDITIONS IN THEIR LOCAL AREA OF INTEREST.
CATEGORIES: LOW (< 200), MODERATE (200-500),
HIGH (500-700), AND VERY HIGH (> 700).
-NOTE: MAX TRANSPORT WINDS MAY NOT OCCUR
AT THE SAME TIME AS MAX MIXING HEIGHT. ***
