Its main function is to predict climate and atmospheric conditions, issue early warnings about dangerous meteorological phenomena, and provide climate information for various activities, such as aviation, agriculture, and navigation.
The SMN operates through a network of meteorological stations distributed throughout the country, in addition to using satellite imagery and numerical prediction models.

These are generally issued 24, 48, or 72 hours before the event. On the other hand, very short-term advisories (ACP) urge the population to take action quickly, as the phenomenon may occur just minutes after the advisory is issued.
An alert may be issued in situations involving rain or storms, as well as extreme temperatures or phenomena that deviate from normal conditions.
