October 31, 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 north and northeastern fire perimeter of the Creek fire remains the most active. Single-digit humidity continues to combine with historically low heavy fuel moistures that will continue to result in the burnout of interior islands. This will continue to produce significant smoke until environmental conditions change. Thermal belts enable active internal burning at elevation throughout the night. Fire information can be found at: inciweb.nwcg.gov/incident/7147/

Smoke: Light northwest high elevation winds should keep the NW portion of the forecast area in good to moderate levels today. These winds are forecast to moderate this afternoon allowing the pooling of smoke in the lowest areas. Then, diurnal terrain-driven upslope-down-valley winds will prevail, smoke levels will begin to peak midday along the western foothills of the fire perimeter through the evening hours. Areas of heaviest smoke impacts will be Prather, North Fork, and Oakhurst, as well as locations in the immediate vicinity of the fire. Some east to southeast winds is anticipated tomorrow afternoon at the ridgetop level. Smoke concentrations will build tomorrow through diurnal daily flow patterns.
