Northwest Fire Weather Summary
Warming and drying will continue through most of the work week as a large blocking ridge of high pressure remains along the coast. Dry easterly winds are expected over sections of Southwest Oregon again today and tomorrow under the influence of a thermal trough at the surface. The blocking ridge should give way going into the weekend, bringing cooler temperatures, breezy winds, and some precipitation. Check the latest NWS fire weather planning forecasts for timing and details for your area.

Northwest Fire Potential Summary
Fire danger will continue to rise through Thursday with the warmer and drier weather. Western Oregon will see the biggest increase in fire danger due to the dry easterly winds. Large fire potential will rise mainly over PSAs NW03 and NW04 due to the combination of drier fuels and gusty east winds. Initiation of new significant fires is not likely, but flare-ups of ongoing incidents are possible due to the elevated burning conditions.
