Fire Weather Index

Numerical rating of fire intensity. It is suitable as a general index of fire danger.

Description & Technical Information


The Fire Weather Index is a variable of the Fire Weather Index rating system designed and adopted by the Canadian Forest Service. This is a good indicator of fire danger because it contains both a component of fuel availability (drought conditions) and a measure of ease of spread. This index has been calibrated on a country-by-country basis.
