Continued activity on multiple fires in Northern California will produce on-going impacts for Humboldt, Del Norte and Trinity counties states a North Coast Unified Air Quality Management District (NCUAQMD) public service announcement.

The announcement states that the Red Salmon Fire has grown to 30,000 acres and smoke will remain elevated and impacts will fluctuate along the coast, ash fallout is possible.

"Interior areas will remain hot and dry with smoke mixing down mid-day and overnight depending on conditions. High temperatures and lower humidity through the Holiday Weekend will keep fires active, increase smoke production, and lead to poor smoke dispersion," the PSA reads.

In Humboldt County, coastal areas are expected to remain “Good” to “Moderate” with possible periods of “Unhealthy for Sensitive Groups” overnight while some ash fallout is possible.

Southern Humboldt County is expected to see “Good” to “Moderate” air quality with possible periods of “Unhealthy for Sensitive Groups," depending on conditions.

Orleans, Hoopa, Weitchpec, and areas along the river drainages will see “Moderate” to “Unhealthy for Sensitive Groups” midday with “Good” conditions possible in the evening hours.
