Red Flag Warnings persist as extreme heat and wind elevate wildfire risk

WENATCHEE — Critical fire weather conditions continue to threaten North Central Washington as Red Flag Warnings remain in effect for eastern Chelan County and Douglas County through 9 p.m. Tuesday, June 10, according to the National Weather Service.

The warnings, issued due to a combination of hot temperatures, low humidity, and gusty winds, follow an Extreme Heat Warning and Heat Advisory already in place through Tuesday evening. The National Weather Service Spokane office warned that these conditions may lead to rapid fire growth from any ignition sources.

“These are dangerous fire conditions,” the agency stated in its latest briefing. “Any new fires that start will have the potential to spread quickly.”

West to northwest winds between 10 and 20 mph, with gusts up to 30 mph, are expected across the warning area. Relative humidity is forecast to drop as low as 15 to 25 percent, drying out grasses, brush, and other fine fuels. The most hazardous period is between 3 p.m. and 9 p.m. each day.

A Red Flag Warning is issued when a combination of strong winds, low relative humidity, and warm temperatures create an increased risk of fire danger. The warning applies to much of Douglas County and eastern Chelan County, including areas surrounding Wenatchee and the Waterville Plateau.

Okanogan County is not currently under a Red Flag Warning but is experiencing similar weather patterns. The region is being monitored for elevated fire weather conditions as very warm and dry air moves through the area.

The weather service said fire concerns will persist into Wednesday, with gusts reaching 25 to 35 mph in central Chelan County and the Waterville Plateau. “Fire control in grassy areas may be an issue,” forecasters said.

Meanwhile, temperatures reached their peak on Monday, with highs expected to hit 101°F in Wenatchee and 104°F in Chelan. A Major HeatRisk level is in effect for north central Washington, signaling the potential for heat-related illness without proper cooling or hydration.

The forecast shows a gradual cooling trend beginning Tuesday night, with the potential for showers and isolated thunderstorms starting Thursday. However, fire danger remains elevated through at least midweek.

The National Weather Service urges residents to avoid activities that could spark fires, including fireworks, yard work, and target shooting. Driving over dry grass, dragging trailer chains, and unattended campfires are also discouraged.

Residents are advised to monitor official updates and follow any directives from local emergency management.
