523 FNUS56 KPDT 091357 FWFPDT Fire Weather Planning Forecast for NE Oregon and SE Washington National Weather Service Pendleton OR 657 AM PDT Mon Jun 9 2025 ...RED FLAG WARNING IN EFFECT FROM 2 PM THIS AFTERNOON TO 8 PM PDT TUESDAY FOR FIRE WEATHER ZONES WA690 AND WA691 FOR BREEZY WINDS AND LOW RELATIVE HUMIDITY... .DISCUSSION... Very hot and dry conditions will persist through Tuesday as strong high pressure remains over the region. As this high pressure begins to break down later today into Tuesday, winds will increase, especially for the Cascade Gaps and into the Columbia Basin. Winds are expected to peak on Tuesday, when critical conditions are expected. These conditions have prompted the issuance of a Red Flag Warning. There is also a chance (30%) of showers and thunderstorms mainly over the mountains of central and eastern Oregon Tuesday afternoon into Wednesday. Temperatures will cool during the mid to latter week period, but no widespread precipitation is in the forecast. ***Winds are 20 foot 10 minute averages*** ***CWR-chance of wetting rain 0.10 or greater*** ***Ventilation Index is derived from the transport wind multiplied by the mixing height in 100's of feet. Index 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.*** Note: Max transport winds may not occur at the same time as max mixing height.
