Early Warning System for Tropical Cyclones

How often have we heard that we are in blue or red alert? What is an Early Warning system for Tropical Cyclones? Well this is a System was created by the National Civil Protection System in 2000, with the aim of keeping people informed when a disturbed system according to its track could affect any part of our country and this way mitigates its effects.

To achieve this, among the main points are mentioned as follows:
  • Using of two cyclone intensity scales: the Saffir-Simpson scale and the scale of circulation.

  • Using of two schedules according to colors: one when the cyclone is aproaching and another when it is moving away.
  • Using of an alert by a fixed color code (Blue, Green, Yellow, Orange and Red) to facilitate understanding of the seriousness of the danger.
  • Incorporation of actions to be followed by the population in each of the stages (1).

Each alert mentions the meaning of color, the distance of the tropical cyclone, the type of danger, issuing weather bulletins, the actions that the government and people should do and more.
