British Columbia Fires and Heavy Smoke

Today we observed heavy density smoke and PM along the Idaho and Montana border due to fires. Fires from the British Columbia region in conjunction with smoke from the Idaho-Montana smoke has produced smoke ranging from low concentration to dangerous density of smoke. This smoke stretches from the Pacific Northwest and through the Rocky Mountain States and the Plain States to the Northeast region of the country (HMS, top left). In the Terra image below (top right) we see concentrations of smoke that maybe unhealthy for sensitive groups over much of Northern Washington. Aerosol Optical Depth (AOD) trajectories (VIIRS CONUS, bottom left) shows the heavy concentrations of both PM and Ozone moving east towards the Mid-Atlantic region and much of New England over the course of the next 2 days. Smoke in the further corner of the Pacific Northwest region will soon find itself in the Pacific Ocean. Wind speed stayed low on the west coast as temperatures reached the upper 90°F (NOAA Climate chart, bottom right). It is believed that the smoke, low winds and high temperatures may have all contributed to the elevated levels of Ozone along the west coast.
