Due to southerly transport winds late Monday, coastal areas of Humboldt and Del Norte County primarily began seeing moderate smoke impacts from the Camp Fire. Additionally, there have been several small fires locally (Green Hill Fire, etc.) but smoke impacts from these fires remains localized.
Overall smoke impacts are forecast to be “Good” to “Moderate” with brief periods of ”Unhealthy for Sensitive Groups” depending on weather and location. Overall today (Tuesday), afternoon smoke dispersion will be somewhat limited. As is typical for this time of year, overnight inversions will limit smoke dispersion until the day starts to warm up. Beginning tomorrow (Wednesday) transport winds will shift and come from the north and areas along the coast should see clearing as smoke will then be pushed south.
Coastal Areas (Crescent City to Shelter Cove) - overall “Good” to “Moderate” with brief periods of “Unhealthy for Sensitive Groups”
- "Moderate" - Unusually sensitive individuals should consider limiting prolonged or heavy exertion.
- "Unhealthy for Sensitive Groups (USG)" - People within Sensitive Groups should reduce prolonged or heavy outdoor exertion (Sensitive Groups are people with heart or lung disease, the elderly, children, and pregnant women).
