The catastrophic effects on structures during tropical cyclones occur mainly by the combined effects such as extreme winds, high waves and flooding, and a deficient structural capacity of facilities. The electrical sector is affected continually for these phenomena, causing important economic losses, besides, falling trees, and flying debris making contact with overhead power lines result in electrical outages. The magnitude and duration of such outages is worsened if the power lines, poles, underground lines, and above ground electrical facilities fail (when transmission facilities fail, restoring the energy services can take several days). Federal Electricity Commission (CFE) as leader of the electrical sector in Mexico spends a lot of money, researching how the effects of tropical cyclones can be decreased and, developing mitigation procedures, to reduce the outages of the energy service. Therefore, in this paper, a procedure to assess the possible damage in the electrical sector facilities’ subjected to wind forces caused by tropical cyclones is proposed (in a first stage, transmission lines and Electrical Substations were chosen). The procedure is based on simplify models, which were implemented in the Geographic Information System named GECITRO, developed to manage the information about tropical cyclones. The program GECITRO includes a module, with four forecasting mathematical models (GFS, MM5, UNAM and the NHC advisory) in order to calculate the probable tracks of tropical cyclones, and parameters like velocity and directions of wind at different pressure levels, precipitation or temperature for a period of seven days ahead. Besides, the program includes a module to develop damage scenarios, using the forecasting wind velocities of the mathematical models. The program was programmed using the languages Silverlight, JavaScript, Python, Java, and C++. The database is managed using SQL Server and the service of maps via WEB and mobile device is provided for ARCGIS Server. Actually, the program is used for the hydrometeorological department of the Federal Electricity Commission.
