Thompson Ridge Fire Update Sunday, August 20, 2023

FIRE SITUATIONWith a few days of strong work through difficult conditions, the firefighters on the Thompson Ridge Fire have achieved 85% containment. Management of the fire will be turned over to the local unit Tuesday morning. 
Humid conditions remained in the region with sporadic rain continuing to fall on the fire. During the day, crews were able to seek out remaining heat sources around much of the perimeter. The Unmanned Aircraft System (UAS) assisted firefighters in this process by identifying the heat sources so crews could mop up any hot spots that threatened the line. The UAS was then released after reconnaissance flights were completed to detect these heat signatures. Fire behavior is expected to be minimal. 
With the current weather, increased and near-record wet fuel moistures, and high humidity, there is little threat to the fire perimeter. Firefighters will continue to work the remaining uncontained portions of the fire’s edge and monitor and patrol the fire area. Potential for growth is low, but fire managers want to ensure as much containment as possible during this period of moderate fire behavior. 
As storms continue to impact the area, firefighters are pulled from the fireline as needed to avoid any injury and minimize danger from flooding. The predicted rain will continue to impact suppression efforts, as it creates unsafe conditions to work in. Firefighter safety remains the number one priority.

CLOSURES Please refer to closure order at Use caution in these areas, with the influx of ground and aviation equipment working in the area.
