Includes bibliographical references (pages 33-34). "The Fire Weather Index (FWI) System codes and indices are commonly communicated and interpreted using a classification system (i.e., Low, Moderate, High, Extreme) by fire management agencies. Adjective classes were developed provincially shortly after the FWI System was introduced nationally in 1969. Class ranges were determined using a climatological frequency analysis, the basis of which was that on 2% of fire season days the FWI values should fall within the Extreme class, and Very Low represented days with FWI values of 0. Since then, these classes have become highly integrated into fire management and are, for example, commonly used for public awareness and education, high level operational preparedness, daily briefings, training curriculum and numerous mapping products. There has been little to no change in class ranges since their inception"--Abstract, page [1]. Fire weather Ontario. Forest fire forecasting Ontario. Forest fires Prevention and control. Canada.
