Here’s an update on how to find out about air quality, smoke plumes and road closures linked to Washington’s massive wildfires. Plus tips on finding out about fires/smoke in Oregon, Idaho and British Columbia and about fire-related road closures.

The smoke from massive wildfires raging in North Central Washington has created unhealthy, even hazardous, air pollution during the past week in some areas within and far beyond the state’s fire-stricken areas.

The rain forecast for this weekend could help ease the fires, and smoke, but conditions change rapidly. Here are ways to get information:

For travelers (and for locals and firefighters), a useful interactive map at the Washington Smoke Information website has air-quality reports from air-monitoring stations that are located throughout the Pacific Northwest and beyond.

Fire/smoke safety for you and others

If you’re driving in thick smoke or in fire-prone areas, here are some tips to safeguard you and others:

• Turn your car’s air conditioner to recirculate so it stops pulling in smoky air.

• Drive with your headlights on.

• Do not throw cigarette butts out the window. In the tinder-dry conditions, they could start a fire.

• Do not park or drive through dry grass on roadsides or rural roads. The heat from a vehicle’s exhaust or a single spark can ignite a fire.

• If you’re camping, be aware that campfires are banned almost everywhere in the West because of the extreme fire danger.

• Oregon Public Health has a useful summary of the health effects of wildfire smoke, and minimizing your risk, at

The map is at and contains information from county, state and federal agencies and Indian tribes. You can use the map, and the air-quality forecasts on the website, to check the air pollution where you are or in places you plan to visit.

Click on “full map” at the bottom of the map, then on the color-coded dots to see the current air quality in a location. At the top right are tabs for a map legend and “layers” which lets you click to see the vast smoke plume that has spread across the western/central U.S. and into Canada.

Air quality is ranked from good to hazardous, based on the particulates level. Particulates are the tiny amounts of matter suspended in the gases that a fire emits; breathing it in can exacerbate or cause heart, lung and other health problems.

When air is ranked as “unhealthy,” as it was in Omak and other communities over the past week, the Washington Smoke Information website explains, “Many more people than average may have breathing problems or have worsened symptoms of existing lung or heart disease … Everyone should limit time spent outdoors … People with asthma, respiratory infection, diabetes, lung or heart disease, or (who) have had a stroke should stay indoors. Infants, children, pregnant women and adults over age 65 should also stay indoors.”
