October 13 to October 19, 2017 – Warm and dry Friday temperatures provide no relief for wildfire conditions which means continued presence of smoke along the North Central Coast Air Basin. Smoke from wildfires in Napa and Santa Rosa has been pushed south through our area and beyond from the week long north wind. Expect increased offshore winds Friday night into Saturday as an upper trough to our west moves onshore and heads east. Temperatures will stay warm through the weekend and early next week but will trend down as we approach Thursday and Friday with a slight chance of precipitation Thursday. During these warm days, the presence of wildfire smoke will keep District locations PM2.5 levels MODERATE for most coastal areas except Santa Cruz and San Lorenzo Valley which have and may continue to experience UNHEALTHY FOR SENSITIVE GROUPS to UNHEALTHY conditions. Inland areas should also expect PM2.5 in the MODERATE to UNHEALTHY FOR SENSITIVE GROUPS range. Residents are encouraged to protect their health when experiencing smoke impacts by reducing physical activity, staying indoors, and avoiding the use of anything that burns inside the home such as wood stoves, fireplaces, etc.
