# Windstorm Probability

Windstorm hazard refers to the average wind speed expressed in m/s. The hazard has 3 severity levels (Low, Moderate, High). Low windstorm hazard intensity corresponds to wind speed between 15 and 20 m/s, moderate to wind speed between 20 and 22.2 m/s, while high to wind speed more than 22.2 m/s. For each of the severity levels, windstorm hazard is calculated for each of the 12 calendar months. The returned values of the windstorm hazard are probabilities of exceeding the above wind speed thresholds per severity class per calendar month.
