September 17, 2020 - The U.S. Forest Service reports smoke and air quality outlook for the San Joaquin-Yosemite areas, due to the Creek Fire.

Fire: The Creek Fire continued to be active yesterday. Containment is 18%, and today elevated fire activity and smoke production will likely continue under SW winds and low humidity. Increased active fire is likely tomorrow under those elevated SW winds. For the latest Creek Fire fire information and details, go to: https://inciweb.nwcg.gov/incident/videos/7147/

Smoke: Yesterday we had a little afternoon clearing, but increased fire activity helped replenish the smoke inversion. Most sites in the forecast area remain in the Very Unhealthy/Hazardous range this morning. Today, SW winds could improve air quality in lower elevation sites on the west side this afternoon/evening. Tomorrow should have the same pattern, but emissions continue to increase from the fire, so expect early morning smoke again, and little east side improvement.

Notes: Forecasts reflect particulate matter from smoke only – not ozone or dust. Poor visibility, potentially less than 1/4 mile is likely under morning smoke inversions.
