October 13, 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 fire was active yesterday near Rattlesnake Lake and along the northeastern fire perimeter. Internal hotspots continue to produce heat and smoke. Fire activity will increase today and throughout the week due to warmer temperatures and lower RHs.  For the latest Creek Fire fire information and details, go to: https://inciweb.nwcg.gov/incident/videos/7147/

Smoke: Cleanest air will be within the Yosemite Valley and high elevation locations north of the fire. Expect heaviest smoke impacts in Mammoth Lakes down to Bishop and locations near the fire perimeter, such as North Fork. Light smoke settled overnight in foothills areas, including El Portal, Mariposa, Ponderosa Basin, Oakhurst, Prather, and Millerton. Expect smoke lifting by mid-afternoon, returning overnight with drainage winds. Today will be the last overall clean day in the region as smoke concentrations increase throughout the rest of the week due to high pressure building in, limiting atmospheric mixing and increasing fire activity.
