Fire officials reported that the rapid spread of spot fires required the deployment of additional crews to support containment. They emphasized that the decision to cancel the prescribed burn earlier that morning was based on unfavorable weather, yet the fire still ignited. Agencies continue to monitor smoke conditions and have advised the public to avoid the closed area. Officials also noted that the Pine Mountain area will remain closed to the public while containment work proceeds.
