Research has shown that wind as low as what speed can create wind-driven fire conditions?

Wind-driven fire conditions can be influenced by even relatively low wind speeds, and research indicates that winds as low as 10 mph can effectively enhance fire behavior. At this speed, wind can influence the rate at which a fire spreads, as it typically pushes flames and heat toward unburned fuels, increasing the likelihood of ignition. Wind also can carry embers and hot particles away from the main fire, causing spot fires to ignite at a distance. Understanding this concept is crucial for fire response strategies and situational awareness, as firefighters must be prepared to adapt their tactics based on environmental factors like wind.
