REDapp is a universal fire behavior calculator developed with financial support from the Canadian Interagency Forest Fire Centre (CIFFC), and in-kind support from fire management agencies across Canada. This application is currently in a beta stage of development, with public release expected in early 2015. Unlike WFDSS, Behave, FSPro and other fire growth models, REDapp is intended to provide basic fire behavior projections with minimal training. Managers introduced to REDapp at a fall workshop in Fairbanks felt the tool could be used by field operatives, dispatchers, managers, and other agency cooperators to link numerical outputs of the Canadian Forest Fire Danger Rating System (CFFDRS) with potential fire behavior and spread. Neal McLoughlin from Alberta Environment and Sustainable Resource Development gave a demonstration of how to use REDapp, using the 2013 Mississippi fire by Delta, Alaska as a test case.
