A rare ‘Particularly Dangerous Situation’ Red Flag Warning — the first ever for Eastern Washington — is in effect this weekend, with critically low humidity, gusty winds, and extended burn periods threatening to drive explosive fire growth.

"Particularly Dangerous Situation" Red Flag Warnings cover nearly all of Oregon east of the Cascades and much of eastern Washington, with temperatures topping 100°F, humidity in the single digits, and gusty winds.

Red Flag Warnings are in effect for central and eastern Washington and parts of Oregon this weekend, with gusts to 55 mph and humidity as low as 15 percent. A historic PDS Red Flag Warning earlier this week drove the catastrophic Spokane area fire runs.

The Pacific Northwest has seen its first "Particularly Dangerous Situation" Red Flag Warnings since 2020, with dry cold fronts delivering 40-55 mph wind gusts, relative humidity in the single digits, and temperatures near 100°F fueling explosive fire growth.

Multiple Red Flag Warnings are in effect across Oregon and Washington, including a rare Particularly Dangerous Situation warning that preceded the catastrophic Spokane-area fires. A thermal trough, triple-digit heat, and critically dry conditions continue to drive extreme fire weather.

The National Interagency Fire Center August outlook forecasts above-normal significant fire potential across most of the northwestern United States through the end of the month. The 2026 season is already running 37% above the 10-year average in total acres burned.

The National Weather Service issued a rare Particularly Dangerous Situation (PDS) Red Flag Warning across eastern Washington and northeastern Oregon over the weekend, citing extreme fire weather conditions including wind gusts up to 45 mph and relative humidity as low as 4 percent.

The National Weather Service issued a rare Particularly Dangerous Situation Red Flag Warning across eastern Washington and northeastern Oregon — the first in the Pacific Northwest since September 2020 — as a dry cold front delivered 45 mph gusts and humidity values below 20%.

The Pacific Northwest has received its first Particularly Dangerous Situation (PDS) Red Flag Warning since 2020, with 40-55 mph gusts and humidity as low as 5% forecast to push existing fires toward explosive growth this weekend.

A rare Particularly Dangerous Situation Red Flag Warning is in effect for eastern Oregon and Washington as extreme winds, heat, and low humidity converge on a region already battling dozens of active fires.

A fire weather watch is in effect for Central and Eastern Oregon as dry thunderstorms, humidity in the single digits to low teens, and above-normal temperatures create dangerous conditions for new ignitions. Forecasters see little relief on the horizon as the persistent hot, dry pattern continues.

Isolated dry thunderstorms are forecast for southern Idaho today, threatening new fire ignitions, while the Blue Mountains face a slight thunderstorm risk. Minimum humidity across the Northwest drops to 10–20%, sustaining extreme fire behavior on active incidents.

Dangerous fire weather conditions — including 90-degree heat, wind gusts over 30 mph, and relative humidity in the single digits — continue driving extreme fire behavior across the Pacific Northwest, with Red Flag Warnings in effect across much of the region.

Red Flag Warnings remain in effect across parts of Oregon and Idaho, with southwest winds of 15-25 mph, humidity as low as 5-15%, and a threat of dry lightning in southwest Montana and Wyoming that could spark new fires across the region.

Critical fire weather conditions are gripping the inland Pacific Northwest, with Red Flag Warnings in effect for central Washington and eastern Oregon, winds gusting to 35 mph, humidity in the single digits, and temperatures approaching 100°F.

A red flag warning is in effect across Central Oregon Saturday as gusty winds and critically low humidity combine with ongoing lightning activity to drive explosive fire growth. The Northwest Geographic Area reported 15 new large incidents in a single day this week.

A Red Flag Warning expanding to cover all of eastern Oregon and Washington today brings wind gusts up to 40 mph and single-digit humidity to parched fuels, creating the highest wildfire risk of the 2026 season.

Critical fire weather conditions continue across Oregon, Washington, and Idaho this week, with red flag warnings in effect for much of the region, temperatures exceeding 100 degrees at lower elevations, and the threat of dry lightning from afternoon thunderstorms adding new ignition risk.

A combination of record drought, critically dry fuels, gusty winds, and lightning-producing thunderstorms has created an extreme fire weather environment across Oregon, Washington, and Idaho, with forecasters warning conditions could remain critical well into August.

Red Flag Warnings are in effect across Central and Southern Oregon through 11 PM Wednesday, with dry thunderstorms, gusty outflow winds, and critically low humidity creating prime conditions for new fire starts and rapid spread. Fuel moisture levels are tracking a full month ahead of their historical averages.
