What is described as a long narrow strip of fire extending from the main fire?

The term "finger" is accurately defined as a long, narrow strip of fire that extends from the main fire. This phenomenon often occurs during wildfires when wind, topography, and fuel conditions allow flames to spread outward in a slender, elongated manner. The appearance of a finger can pose significant challenges for firefighting efforts, as it may create new fire spots away from the main blaze, leading to the potential for rapid spread and making containment more difficult. Understanding the behavior of a fire finger is crucial for firefighters in planning appropriate strategies for suppression and ensuring safety on the scene.
