Current Status:
The Nature Grove Fire grew to 676 acres yesterday and continues burning in a southeasterly direction. For the last several days, air crews and firefighters have been using multiple resources to slow this fire’s spread. Fire is burning in timber, litter and understory with uphill runs, group torching and flanking. Water drops were conducted yesterday and were helpful in slowing the fire’s spread. Today, ground resources including heavy equipment, engine crews, and hotshots will continue to focus on protecting structures along Highway 38 (Skalkaho Hwy), laying hose line, creating fuels breaks. To the west, crews will be working to secure the fire’s western flank and widen Forest Service Road 1370 for access and to aid in suppression efforts. Air resources include four helicopters and a Black Hawk that will be arriving this afternoon.
Additionally, crews were successful at slowing the spread of the Bear Gulch Fire yesterday, securing it with handline and dozer line. Crews will continue to work towards containment of that fire and begin mop-up in the coming days.
Weather and Fire Behavior:
Hot, dry conditions with potential thunderstorms resulting in strong, erratic outflow winds and lightning are expected through Thursday. The chance of wetting rain is low (confined to thunderstorm cores) but gusty outflow winds of 35 to 45 mph could enhance fire behavior in the afternoon/evening. Slightly cooler weather is expected Friday with increasing RH and the potential for wetting rains over the weekend.
Closures:
Forest Service Road 75 is closed from Highway 38 to the junction of Forest Service Road 720. FS Roads 720 and 711 remain closed. There is a Temporary Flight Restriction (TFR) in effect over the Nature Grove Fire. Flying any aircraft, including drones (UAS), is prohibited.
