Extreme fire behavior indicates a level of fire behavior characteristics that ordinarily precludes methods of direct control action. One or more of the following is usually involved: high rate of spread, prolific crowning/spotting, presence of fire whirls, and strong convection column. This webinar will summarize the recent JFSP publication that connects the weather, fuel, and topographic factors that contribute to development of extreme fire behavior. This webinar was presented by Paul Werth, and hosted by the Southwest Fire Science Consortium.
