North Coast Unified Air Quality Management District press release:

Numerous fires remain active throughout Oregon and Northern California. The main fires that have the potential to impact our area are the Natchez Fire (N/E Del Norte County, CA), Carr Fire (Shasta County, CA), Mendocino Complex (Mendocino & Lake Counties, CA), Garner Complex (Southern OR), and the Klondike Fire (OR).

Expect smoke from the northern fires to pool along the river drainages, impacting the very northern interior portions of Del Norte and Humboldt Counties. Depending upon location, air quality along the coast is expected to remain generally “Good” to “Moderate” with periods of “Unhealthy for Sensitive Groups (USG)”.

The Carr Fire east of Weaverville in Shasta County may present widespread haze to the Trinity Center, Lewiston, and Weaverville areas. The Mendocino Complex may present smoke impacts to Southern Humboldt depending upon location and fire behavior. Overall, smoke dispersion is forecast to continue to improve toward the end of the week.

  •  Klamath is expected to have “Good” conditions with periods of “Moderate” air quality. 
  • Gasquet is forecast to have “Moderate” conditions on Friday, with periods “USG”. 
  • Orleans and Hoopa are forecast to have “Moderate” conditions with periods of “USG”, but transition to generally “USG” over the next few days. Periods of “Unhealthy” may occur in the evening time in the valley. 
  • Weaverville area is forecast to have “Moderate” conditions with periods of “USG” and “Unhealthy”, and perhaps worsen depending upon the Carr Fire’s behavior.

Particulate Matter (PM2.5) monitors are presently in Gasquet, Klamath, Weitchpec, Orleans, Hoopa, Weaverville, and Eureka. Updates will be provided as conditions change. For 24-hour Air Quality Advisory Information, call toll-free at 1-866-BURN-DAY (1-866-287- 6329).
