South Fork Fire Wildfire
News – 8/23/2017

Smoke: Smoke in the lower valleys of Yosemite, especially near Wawona, will again be dense through noon today, improving through the afternoon. Likely short-term moderate smoke impacts to nearby foothill locations (Mariposa, Oakhurst), primarily in the morning. Tuolumne Meadows could also experience afternoon smoke impacts. Fire: South Fork: 4012 acres, 22% contained. Decrease in areal cloud presence and thunderstorms this afternoon. Butte: Full containment. Empire: Monitor status, only light activity expected. Other: Dense smoke for short periods can aggravate symptoms for sensitive persons without changing 24-hr AQI levels. Afternoon thunderstorms again today. Outflow winds from these can push smoke into new areas for a couple hours at times as well as increase fire behavior and smoke production. Note: AQ forecasts below reflect only particulate matter - not ozone.
