Red Rock and Black Eagle Fire Daily Update 09-27-2024
Publication Type: News - 09/27/2024 - 09:50
FIRE ACTIVITY:
The Red Rock Fire is at 3,208 acres and 73% containment.
The recent successful efforts constructing containment lines around the northwest corner of the fire has allowed those areas to move into mop-up status and those crews to refocus on the eastern edge of the fire. Crews continued to establish handlines along the remaining uncontained sections of the perimeter. Problematic weather with gusty southwest winds is being forecast for the weekend, prompting the increase in staffing on the eastern edge of the fire. Ground crew work is being augmented with heavy aircraft support.
The Black Eagle Fire is at 6,825 acres and 8% containment.
The majority of the fireline of the Black Eagle Fire exists inside the Frank Church Wilderness and is being monitored for growth where the additional acreage was added. The majority of fire growth and visible smoke is remote and within the wilderness area. The areas outside of designated wilderness have seen increased fire behavior due to recent gusty winds, warm temperatures, and low relative humidities. These sections of line are being fully suppressed, with structure protection efforts for the Black Eagle Mine as contingency.
WEATHER:
The weak weather system that moved through region yesterday morning brought some increased winds but cooler temperatures and slightly higher relative humidities, which moderated fire behavior. A weak high pressure ridge will build over the area Friday bringing higher temperatures and lower humidities, but the southwest winds will diminish to 6 mph with gusts to 16 mph. Saturday will see warmer temperatures and afternoon gusts up to 25 mph. Sunday will be cooler but with afternoon gusts up to 40 mph.
FIRE BEHAVIOR:
Decent overnight humidity recoveries have moderated fire behavior across both fires. Areas where humidities fell below 25% with gusty winds did experience some increased activity in heavy dead and down fuels. Controlling spot fires and direct line construction in these areas has been the most difficult.
