Fire weather conditions in the Pacific Northwest remain at a crisis level as of August 15, 2026. Red flag warnings — the highest tier of fire weather alert — are in effect for much of eastern Oregon and eastern Washington, with gusty winds and critically low relative humidity creating the potential for rapid and extreme fire spread.

Current Red Flag Conditions

The National Weather Service has issued red flag warnings covering a broad swath of the interior Pacific Northwest. The primary drivers of the current fire weather pattern include:

  • Gusty southwest and west winds up to 25–35 mph on exposed ridges, with gusts higher in canyons
  • Relative humidity falling to 10–20% at the surface during afternoon heating hours
  • Temperatures 5–10°F above seasonal normals across much of eastern Oregon and Washington
  • Fine fuels (grass, cured brush) at critically low moisture levels after weeks of heat and drought

Fire behavior analysts note that these conditions are sufficient to cause any new ignition to become a large fire in a matter of hours. Existing fires are expected to show active to extreme fire behavior this afternoon and into the evening hours.

Dry Lightning Threat

The National Interagency Fire Center’s August 14 weather briefing highlighted a concerning pattern: isolated mixed wet/dry thunderstorms are possible across the southern Cascades, northeast Oregon, and far western Idaho. Dry lightning — where storms produce lightning but rain evaporates before reaching the ground — is considered the single most significant source of new fire starts across the interior West.

Forecasters say the highest confidence in dry lightning is expected from northwest California and the southern Cascades, east across Oregon and into far western Idaho. Residents and outdoor recreationists should be alert to changing storm conditions and the possibility of new fires starting in the next 24–48 hours.

August Outlook Remains Above Normal

The NIFC’s monthly and seasonal fire potential outlook, issued August 1, forecasts above-normal significant fire potential across most of the northwestern United States for August. The outlook covers central Utah, northwest Colorado, western Wyoming, and northwest Montana westward to the Pacific coast.

This elevated potential is the result of converging long-term drought, below-normal snowpack from the 2025–26 winter, and the late-season spread of cheatgrass and other invasive annual grasses that cure earlier and carry fire more readily than native vegetation.

What Firefighters Are Watching

Incident commanders on large fires across the region are prioritizing defensible space around communities and critical infrastructure during today’s high-risk window. Crews are pre-positioned in threatened communities where possible, and air attack resources are on standby at tanker bases throughout the region.

The public is reminded that any outdoor burning — campfires, yard debris, agricultural burning — is prohibited in most of the region under active burn bans. Oregon and Washington both have statewide or near-statewide bans in effect. Violation of burn restrictions carries criminal penalties and civil liability for suppression costs.
