What are holdover fires known for in the context of wildfire suppression?

Holdover fires are specifically characterized by their potential to reignite after initial suppression efforts. This phenomenon occurs when a fire, although seemingly extinguished, has remaining heat sources, such as hot embers or smoldering materials, that can flare up again under the right conditions, such as increased wind or drier weather. In the context of wildfire management, it is crucial to recognize and monitor holdover fires, as they can lead to new fire outbreaks if not adequately addressed.

The ability of a holdover fire to reignite can pose significant challenges for firefighting crews, as these fires may not be immediately visible, making them deceptively dangerous. Understanding this characteristic helps firefighters develop strategies for monitoring previously burned areas to ensure that any potential reignitions are swiftly contained.
