September 18, 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 was less active yesterday, with the majority of the activity on the north and west portions of the fire. Low winds and increased humidity reduced the fire activity, leading to more smoke accumulation. Today fire activity will likely increase with the forecasted increased winds, depending on cloud cover.  For the latest Creek Fire fire information and details, go to: https://inciweb.nwcg.gov/incident/videos/7147/

Smoke: There was minimal clearing in the forecast area yesterday, due to cloud cover. Today, conditions are lining up for some improvement: this morning, rain helped to clear some smoke out and continued stronger southwest winds on the ridges will likely clear the western sites in the forecast area. Smoke production from fire activity today will settle back into the drainage's tonight. Tomorrow, light winds will likely allow more smoke accumulation and strengthen smoke inversions.

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.
