Smoke Will Make Areas of Humboldt and Trinity Counties Unhealthy Today

While more than 560 wildfires burn across the province, it may come as no surprise to hear that B.C. and areas of Alberta now have the worst air quality in North America, according to climate science analysis website Berkeley Earth.

In addition to being more reliable, the new site also includes meteorological data, downloadable historical data and analysis tools, and information from the Lane Regional Air Protection Agency.

Officials warned older residents and young children or people with heart or lung disease to "avoid prolonged or heavy exertion".

Wildfires burning in Washington state and British Columbia are causing high concentrations of fine particulate matter to move in.

When the air quality is poor, keep your activity to levels that don't increase your rate of breathing too much. If you have an air conditioner, use the "recirculation" switch. That's what experts recommend people should do in the summer now - stay indoors with filtered air.

The health risks associated with the smoke are accompanied by the melancholy views caused by hazy conditions. A high pressure system is pushing upper-level wildfire smoke down.

Similar conditions prevailed in Calgary, where even trying to make out the city's skyline from any distance proved hard.

As the Miriam Fire rages on near White Pass, visibility in that region has largely been obscured as well, said U.S. Forest Service recreation planner and wilderness manager Andrea Durham.

The current conditions are expected to last a few days, but Tuesday is expected to be the worst day for the metro area.

Air quality conditions may change quickly.
