Current Situation: Favorable weather and fire behavior gave crews an opportunity to get closer to the fire’s edge, where intense and challenging fire behavior prevented them from working before. Hand crews worked direct on the north and west sides of the fire. They are trying to patch together the existing network of old trails with hand lines in the steep terrain and using heavy equipment to build dozer lines where the slopes are more gradual. The terrain makes this line construction extremely difficult and progress is slow. Several indirect contingency lines are nearing completion, providing a backup in case direct tactics are not effective. Along Rabbit Creek Road (327), firefighters chipped debris and mopped up hotspots to gain additional containment.
Joining these crews today is a taskforce of 69 fire personnel from Australia and New Zealand. The United States and these southern hemisphere nations have an ongoing relationship of sharing resources, due to their fire seasons taking place in opposite times of the year.
Safety: Public safety and firefighter safety remain top priorities. Fire crews will adapt operations to weather, fire behavior, terrain, and road/trail conditions. Please observe all road closures and keep roads clear for emergency vehicles. Drive slowly and be extra vigilant while navigating areas with heavy fire traffic.
Weather and Fire Behavior: Showers dispersed during the day on Thursday but continued last night into the morning, bringing approximately 4/10ths of an inch across the fire area since the rain event began. This increase in moisture, along with cooler temperatures, moderated fire behavior, with just creeping and smoldering observed in most areas. More showers are forecast Friday night before somewhat higher temperatures and lower RH values return Saturday afternoon through Sunday.
Smoke: Smoke from the Crooked Fire has decreased significantly over the past 24 hours. The forecast calls for continued precipitation, which should keep smoke impact to a minimum. See Airnow.gov for more information.
Evacuations and Closures: There are no evacuations in place. A Forest Closure Order is in effect for trails, roads, and the area surrounding the fire to protect the public from hazards.
