Wildfire smoke is expected to move into the Bellingham area through Tuesday, August 25, while fire danger remains at Very High across both the lowlands and Cascades of Whatcom County, according to the county's Emergency Management Daily Briefing released Monday, August 24.
The Whatcom County Division of Emergency Management says its Emergency Operations Center is not activated, and there are no active advisories, watches, or warnings currently in effect for the county. However, air quality is expected to be moderate to unhealthy for sensitive groups at times through Tuesday, driven by smoke particles from wildfires burning in eastern and central Washington. The overall weather picture is otherwise fairly quiet, but the combination of smoke, drought conditions, elevated fire danger ratings, and the prospect of dry lightning later in the week creates a situation worth watching closely.
Fire Situation in Eastern Whatcom County
Fires are burning in the far eastern part of Whatcom County, in the area around Ross Lake near North Cascades National Park. County emergency managers say they are aware of the fires but have no direct involvement in response activities. The county is in contact with incident management teams handling the Ptarmigan Fire, with additional information available through the North Cascades National Park Service.
The Washington Department of Natural Resources fire danger level for both the Whatcom County lowlands and the Cascades is rated Very High. That rating reflects conditions across a broad swath of the county, not just the mountainous eastern reaches. The DNR assigns fire danger levels based on a combination of wind speed, relative humidity, temperature, and the moisture content of dead and live vegetation. When all of those factors align toward dryness and heat, as they have during this stretch of summer, even a small ignition source can rapidly become a significant fire.
A Stage 2 burn ban has been in effect countywide since July 17, prohibiting all open burning. Residents and businesses that violate the burn ban can face fines, and the restriction applies to everything from agricultural burns to recreational campfires on private property outside of designated campfire areas. Stage 2 is the most restrictive level of burn ban in Washington state, and its continued enforcement reflects how seriously county and state fire managers are treating current conditions.
The Washington Department of Ecology declared a drought for Whatcom County as of April 8, 2026. The U.S. Drought Monitor shows most of the county as abnormally dry, with far eastern portions in moderate drought conditions. The drought has reduced soil moisture and vegetation health across the region, contributing to elevated fire danger even in areas that received normal winter precipitation. Snowpack melted earlier than usual in the North Cascades this year, leaving high-elevation terrain drier than typical for late August, which compounds the challenge for firefighters working on the Ptarmigan Fire and other active incidents in the mountains.
Air Quality and Health Guidance
Smoke from the ongoing wildfires in eastern Washington is being pushed westward by prevailing winds. The National Weather Service and county emergency managers expect air quality to remain at substandard levels through Tuesday before a shift in wind patterns brings relief by Wednesday. Rain showers are possible Thursday and Friday, which could further improve conditions.
Wildfire smoke contains fine particulate matter, specifically particles smaller than 2.5 micrometers in diameter, known as PM2.5, which can penetrate deep into the lungs. Unlike larger dust particles that the body's upper respiratory system can filter out, PM2.5 particles reach the bronchioles and alveoli, where they can trigger inflammation and exacerbate existing respiratory and cardiovascular conditions. Even brief periods of elevated exposure can cause symptoms in sensitive individuals.
For people with asthma, heart or lung conditions, the elderly, children, and others who are sensitive to air pollution, moderate to unhealthy air quality levels mean real health risks. Residents in those categories are advised to limit outdoor exertion on days when smoke is visible or when air quality monitoring shows elevated particle levels. Keeping windows and doors closed, running indoor air purifiers with HEPA filters, and staying hydrated can all help reduce exposure. When outdoor activity is unavoidable, wearing a properly fitted N95 respirator provides meaningful protection compared to a standard cloth or surgical mask, which does not filter fine particles effectively.
Up-to-date air quality readings for the Bellingham area and across Whatcom County are available through the Northwest Clean Air Agency, which monitors pollution levels at stations throughout the region. The Whatcom County Health and Community Services department also maintains a wildfire smoke information page with guidance specific to local conditions. Residents can also use the AirNow app or website, which aggregates monitoring data nationwide and provides color-coded Air Quality Index readings that are easy to interpret at a glance.
Weather Outlook and What Comes Next
Beyond the smoke concern, the near-term weather pattern for Bellingham and the surrounding area looks dry through Wednesday night. Temperatures will remain warm with sunny skies on Tuesday before occasional rain showers return Thursday and Friday. Thunderstorms are possible both Thursday and Friday night, which could bring lightning to areas still under fire danger, a combination that warrants close monitoring by county emergency managers.
Dry lightning, meaning lightning that falls in conditions where rainfall evaporates before reaching the ground, is one of the leading causes of new fire starts in the Pacific Northwest during late summer. If thunderstorms materialize over the Cascades Thursday or Friday night while fuel moisture remains critically low, firefighters could face additional ignitions at a time when resources in the region are already stretched by existing fires. Emergency managers are tracking this possibility and will provide updated guidance if the threat becomes more concrete.
On the water, conditions in the Strait and inland coastal waters of Whatcom County will feature northwest winds at 5 to 10 knots today, easing overnight. Wind waves are expected to stay at around 2 feet or less. Patchy dense fog is possible in the morning hours. Tomorrow, winds will be light and variable, becoming west around 5 knots in the afternoon, with wind waves remaining at about 2 feet or less. Boaters can check real-time coastal weather and tidal data through the Cherry Point NOAA Tide Station for the most current conditions on the water.
Residents who want to receive emergency alerts specific to their address, including notifications about air quality advisories, fire danger changes, or evacuation orders, can sign up through WhatcomReady, the county's official emergency notification system. Signing up with a current address ensures that location-specific alerts, such as an evacuation order affecting a particular neighborhood or corridor, reach residents directly on their phones rather than only through broadcast media. Community Emergency Response Team training is also ongoing for residents who want to be better prepared to help their neighbors during local emergencies.
