Yesterday’s winds caused a short spike in air pollution

Yesterday afternoon’s winds brought in dust from the Columbia Basin. The screenshot of the dust event shows data collected at Turnbull Wildlife Refuge. It was a short-lived spike, thankfully. Dust (particulate matter) climbed very close to the Unhealthy for Sensitive Groups/Orange on the Air Quality Index (AQI). These charts can be found on our Current Air Quality Page. Scroll down to the monitoring map and click a site location. From there you can select a five-day trend chart for each pollutant measured at that site.

Protect yourself during dusty conditions:

  • Reduce your active time outdoors.
  • Close windows, doors, and vents.
  • Watch for sudden changes in visibility while driving.
  • Avoid driving during windy conditions when windblown dust is likely.

Help reduce the amount of dust created locally, by:

  • Avoid driving on unpaved roads. If you can’t, drive slowly.
  • Use a broom and dust pan to clean paved surfaces like driveways and sidewalks, not leaf blowers.
