Yosemite Smoke/Fire Conditions 9/14 to 9/15

Smoke Outlook  San Joaquin-Yosemite – Area (Creek Fire)
9/14 – 9/15
Issued: 2020-09-14 08:14 (PDT)

Fire: Yesterday containment went up to 10% on the west and south side of the fire with increased fire activity on the north end of the fire. This increased activity is driving our smoke impact. For the latest Creek Fire fire information details, go to:

Smoke: Yesterday, the Creek Fire produced substantially more smoke than the past few days, leaving this forecast area with uniformly Very unhealthy/Hazardous air quality this morning. Today south winds may be slightly more westerly, sending smoke plumes directly north and potentially clearing some west-side sites in the afternoon. More fire activity is likely, creating continued heavy smoke impacts this evening on the east side, and likely more smoke tomorrow morning throughout the forecast area.

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.
