The Canadian Fire Weather System is briefly described and the meaning of each one of its components is given. Data from direct field measurements of fine fuel moisture content in Central Portugal were used to establish predictors of moisture content of litter and of shrub vegetation. The ability of ISI to predict rate of spread in shrub vegetation is shown.
