North Coast Unified Air Quality Management District public service announcement:

Numerous fires remain active throughout Oregon and Northern California. The main fires that have the potential to impact our area are the Natchez, Garner Complex, Klondike and Carr fires. The Natchez, Garner Complex, and Klondike fires are located in Southern Oregon (closest to the California border). The Carr fire is located in Trinity County, East of Weaverville.

The current weather forecast indicates continued high temperatures and a shift back to Northerly winds beginning sometime Thursday evening into Friday. This will bring a return to smokier conditions in Northern California. Expect smoke from these fires to pool along the river drainages, impacting the very northern interior portions of Del Norte, Humboldt, and Trinity Counties. Depending upon location, air quality along the coast is expected to remain “Good” to “Moderate” with periods of “Unhealthy for Sensitive Groups”. Impacted interior areas can expect air quality conditions of “Moderate” to “Unhealthy for Sensitive Groups” with the potential for increased smoke along the river drainages.

Particulate Matter (PM2.5) monitors are presently in Gasquet, Weitchpec, Orleans, Hoopa, Weaverville, and Eureka. Fire information can be found at http://inciweb.nwcg.gov/ or at www.calfire.ca.gov. Current weather information can be found at www.wrh.noaa.gov.
