Firefighters are continuing direct attack operations, working along the fire’s edge to secure the perimeter and limit further growth. Crews remain actively engaged on the incident and will continue strengthening control lines and addressing areas of heat where conditions allow.
There is a small chance of isolated showers this evening. Any developing storms could produce strong, gusty outflow winds, which may influence fire behavior and will be closely monitored by firefighters.
The Porcupine Basin Trail remains open at this time. Visitors should expect increased fire traffic along Beaver Creek Road #4106. Signs will be posted on both sides of Huckleberry Pass to notify travelers of ongoing fire operations and increased fire-related traffic. Motorists and trail users are asked to slow down, use caution, and remain alert while traveling through the area.
