Weather & Fuels

July 4th is the highest human-caused wildfire ignition day of the year, and 2026 conditions are especially dangerous. With Red Flag Warnings, critically dry fuels, and a building heat dome in place, fire agencies across the Pacific Northwest urge caution with fireworks, campfires, and vehicle use.

Red Flag Warnings are persisting across Eastern Washington as a dangerous heat wave builds ahead of July 4th. Wind gusts of 30–45 mph and humidity as low as 10–20% are creating extreme fire spread conditions across the Columbia Basin, Okanogan Valley, and Spokane area.

Red Flag Warnings covering large portions of Eastern Washington reflect a dangerous combination of gusty winds, critically low humidity, and unusually dry fuels for late June — setting the stage for rapid fire spread with any new ignition.

Red Flag Warnings are in effect across Eastern Washington and Northern Oregon as gusty winds, low humidity, and parched fuels create extreme wildfire conditions this weekend.

Red Flag Warnings are in effect across eastern Oregon (Baker, Malheur, Harney counties) and Washington (Columbia Basin, Kittitas Valley) as gusts of 25–45 mph combine with low humidity and dry fuels.

A dangerous fire weather pattern combining dry thunderstorms, erratic outflow winds exceeding 60 mph, and extreme heat is affecting the Pacific Northwest and Intermountain West. EXTREME fire danger is in effect for Central Oregon, and forecasters warn of additional new fire starts from dry lightning.

Red Flag Warnings have been issued across the Columbia Basin of Oregon and central Washington, while Central Oregon federal lands have reached EXTREME fire danger — the highest possible rating. A dominant high pressure ridge is keeping conditions hot, dry, and windy through the end of June.

A rebuilding high-pressure ridge is driving temperatures into the 90s and dropping relative humidity to single digits across parts of eastern Oregon, Washington, and Idaho this week.

Red Flag Warnings from the NWS Pendleton office are covering large portions of eastern Oregon and Washington, driven by winds, single-digit humidity, and extreme heat. The fire weather pattern is expected to persist.

Drought, early fire season, red flag warnings, and a developing El Niño are converging to create one of the most dangerous fire summers on record for the Pacific Northwest. NIFC forecasts above-normal fire potential through at least September.

The National Weather Service has issued Red Flag Warnings for central Washington and Oregon for Saturday, June 20, as a dry cold front brings gusts to 30 mph and afternoon humidity values in the mid-teens — dangerous conditions atop an already active fire environment.

A cold front sweeping through the Pacific Northwest on June 16 produced the critical fire weather that sparked multiple large fires across eastern Washington and Oregon. Forecasters warn conditions will remain dangerous through the weekend.

Red flag warnings spanning Oregon, Washington, and Idaho this week have flagged dangerous combinations of gusty winds, low humidity, and extreme heat — conditions that have already driven explosive fire growth across the region.

Red Flag Warnings covered eastern Washington and northeast Oregon on June 16, with 45-50 mph gusts and humidity as low as 12% fueling critical fire weather. The Upriver Fire near Spokane validated the threat hours after the warning was issued.

The National Weather Service in Pendleton has issued a Red Flag Warning for central and eastern Washington and northeast Oregon through 11 PM Tuesday, citing high winds, gusts to 45 mph, and afternoon relative humidity as low as 19%.

Critical fire weather conditions — low humidity, gusty winds, and temperatures exceeding 100°F — are gripping the West this week. A dry lightning threat in the Southwest and deteriorating fuels east of the Cascades are raising alarm bells for the week ahead.

A heat advisory is in effect for the Pacific Northwest June 14–16, with Portland forecast near 100°F. The dangerous heat raises wildfire risk sharply, with red flag conditions possible east of the Cascades.

Federal fire forecasters have issued above-normal significant fire potential outlooks for the entire Northwest Geographic Area from July through September 2026, driven by below-normal snowpack, dry spring conditions, and a warming summer pattern.

NIFC's Predictive Services unit has flagged above-normal fire potential for the Northwest Geographic Area from July through September, as snowpack deficits, dry conditions, and early heat combine to create a challenging environment for fire managers in Oregon, Washington, and Idaho.

A significant mid-June heat dome is driving Red Flag Warnings for central Oregon fire weather zones, with dry thunderstorms and gusty winds forecast as a cold front approaches Friday.
