Abstract: 
The purpose of this paper is to present a stochastic approach of the expansion of adverse environmental events which are enhanced by the wind. Our model follows a scheme based on the well-known Susceptible-Infected-Recovered (SIR) model. The expansion takes place in a grid where the cells represent an individual (or even a group) in the population under study. The state of the cells is modelled by a random variable which is a measure of the intensity and direction of the wind. As time passes, the status of the cells is determined according to both an update criterion and a probabilistic neighbourhood relationship.
