In the event of a wildfire, accurate evacuation planning information can have a huge impact on life safety. Traditional fire behavior prediction tools require information (such as an origin or an up-to-the-minute location of the flaming front) to run simulations. Often, this information is not readily available in the chaotic environment surrounding the initial response to a wildfire. Planning for a wildfire event is only effective if it is flexible, taking into account a variety of contingencies (fire location, weather conditions, etc.) from the start. This type of flexibility is not common in standard pre-planning practices. Time Until Fire Arrival (TUFA) is a new GIS tool, designed as an ArcMap ModelBuilder product, to map the shortest potential time it would take a fire to reach a pre-determined value-at-risk or area of concern, regardless of where it ignites on the landscape. TUFA takes the form of a map with isochrones (lines of equal time) depicting the time until a fire will arrive. This tool can be used in multiple ways including determining trigger points for evacuation or production stoppage (for the oil/gas or mining industry). The presentation will address the background, technical challenges, potential uses and future directions for TUFA.
