Summary: Higher temperatures and lower humidity levels combined with gusty winds to increase fire activity in the upper portions of the Ashley Creek drainage on Tuesday. The main body of fire responded to the fire weather conditions by moving across the bottom of the drainage and spread onto the northern slope. Once the smoke lifts late this morning, fire managers will assess the status of the Ashley creek drainage.  Crews continue to patrol and monitor fire activity in areas that have been contained while other fire personnel are conducting mop up operations along the west perimeter of the fire.

Yesterday: Fire activity increased in the upper portions of the Ashley Creek drainage leading to an increase in smoke production. Heavy equipment was used to thin vegetation in the bottom of the drainage to improve Ashley Creek Road as a possible check line in Division November. Personnel in Divisions Echo and Juliet scouted to identify potential control lines and began improving established roads from Liver Ridge to Goat Lake. Divisions Charlie and Zulu are being monitored for fire activity and crews conducting mop up operations are finding almost no heat within 100-feet of the control lines.

Today: In Division November, firefighter will assess the fire spread in the upper areas of the Ashley Creek drainage to determine the level of firing operations firing operations that will be needed between Ashley Creek and the Thompson River. Firefighters will monitor fire activity in Divisions Charlie and Zulu as structure protection personnel remove equipment that is no longer needed. With control lines completed in Divisions Echo and Juliet, fire personnel will be scouting to identify potential alternate control line locations and control features that could slow fire spread between Goat Lake and Liver Ridge.   

Weather:  Temperatures will continue to climb with high temperatures in the 80’s on the fire and humidity levels dropping into the twenties. Winds will be gusty this morning, 15 to 25 m.p.h., but are expected to calm heading into the afternoon and evening. Temperatures are expected to continue to warm with decreasing humidity levels through the end of the week.
