June 21, 2023 - Evening Update - Burn operations for today have concluded successfully. With approximately 1,392 acres accomplished so far, crews are making good progress.

Crews completed the southern side of Thomas Mountain, a significant milestone in the operation. With today’s successful operations and reported favorable weather conditions expected tomorrow, the crews will focus on the interior area of the prescribed burn area. They will utilize aerial ignitions, which involve using aircraft to drop incendiary devices to help ignite targeted areas. This approach assists with containing the fire within the predetermined boundaries.

The San Bernardino has three helicopters on the forest. Helicopter 535 has been playing a crucial role in supporting ground crews with aerial ignitions throughout the week. By working on the interior area, the crews aim to eliminate any remaining fuel sources and secure the containment lines. This is crucial to prevent the fire from spreading further and to ensure its safe management.

Having a helicopter actively engage in aerial ignitions provides a valuable asset to ground crews, enabling them to address fire management challenges from multiple angles. The coordinated efforts of the crews and the utilization of both ground and aerial ignitions demonstrate a strategic approach to firefighting and safeguarding surrounding areas from further damage.

The fire is still burning within the unit and sending up smoke; at times visible from Highway 74. Crews will be monitoring and working throughout the evening. Operations will begin again tomorrow at 9am.
