Dangerous fire weather conditions are expected to persist across the Pacific Northwest and northern Rockies through at least mid-week, according to the National Weather Service and the Northwest Interagency Coordination Center (NWCC). The combination of above-normal temperatures, critically low relative humidity, and erratic winds continues to fuel rapid fire spread across Oregon, Washington, and Idaho.

Current Fire Weather Conditions

As of July 15, fire weather meteorologists are tracking several key hazards across the region:

  • Relative humidity: Values dropping to 10–20% during peak afternoon heating in eastern Oregon, Washington east of the Cascades, and central-southern Idaho
  • Temperatures: Afternoon highs running 5–10°F above normal, with valleys reaching the upper 90s to low 100s in some locations
  • Winds: Gusty, erratic surface winds associated with afternoon heating and approaching frontal systems; localized downsloping winds amplifying fire danger in canyon and foothill terrain
  • Fine dead fuel moisture: 10-hour and 100-hour fuel moistures are critically low across much of the interior PNW, making fuels receptive to ignition and rapid combustion

Red Flag Warnings — Idaho

The National Weather Service office in Pocatello issued Red Flag Warnings for Idaho fire weather zones 475 and 476 on July 11, with conditions calling for gusty winds and relative humidity falling below threshold values from 1 PM to 9 PM MDT. Similar conditions are forecast to recur through the week. Under Red Flag conditions, any new ignition has the potential to spread explosively and become a large fire within hours.

NWCC Fire and Fuels Behavior Advisory

The Northwest Interagency Coordination Center issued a Fire and Fuels Behavior Advisory on July 14, 2026, flagging heightened concern about fire behavior across the region. The advisory highlights that dead and downed timber — accumulated from years of drought stress, beetle kill, and disease — is contributing to unusually active fire behavior for early- to mid-July.

Monsoonal Moisture: Help or Hazard?

A monsoonal moisture surge originating in the Southwest is expected to push northward through the week, reaching into the northern Great Basin, eastern Oregon, and northern California. This system carries the potential for scattered wet thunderstorms that could deliver meaningful rainfall to fire-affected areas — but also dry lightning with little or no accompanying precipitation.

Predictive services meteorologists caution that additional showers and wet thunderstorms are expected to develop over the Northern Rockies late in the day, but lightning-caused ignitions remain a significant concern where precipitation does not reach the surface.

Northwest Preparedness Level

The Northwest Interagency Coordination Center's regional Preparedness Level currently stands at PL 3 (out of 5), indicating that regional resources are substantially committed to active incidents. With the National PL at 4, ordering resources from outside the region is increasingly competitive.

What to Watch For

  • Additional Red Flag Warnings are possible for the eastern slopes of the Cascades and Snake River Plain through the week
  • Thunderstorm development over elevated terrain — watch for new smoke reports
  • Overnight recovery of relative humidity has been poor, leaving fuels pre-heated heading into each afternoon
  • Spot fire potential is elevated — embers can travel significant distances ahead of the main fire front

Residents across fire-prone areas of Oregon, Washington, and Idaho are urged to avoid any outdoor burning or activities that generate sparks, observe all current fire restrictions, and remain prepared to evacuate quickly if a fire threatens their community.
