The SMN is responsible for forecasting weather, issuing warnings for hazardous phenomena, and providing climate information for various applications, including aviation and agriculture. Its operations rely on a network of weather stations, satellite data, and numerical prediction models.

Furthermore, the report explains the purpose and structure of meteorological alerts issued by the SMN. An alert is defined as the "possible occurrence of a meteorological threat," designed to help the public make informed decisions. These alerts are typically issued 24 to 72 hours in advance, while very short-term advisories (ACP) are for phenomena expected within minutes.

The different alert levels are also detailed: Yellow alerts signify potential for damage and temporary disruption; Orange alerts warn of dangerous phenomena posing risks to society, life, and property; and Red alerts indicate exceptional phenomena that could lead to emergencies or disasters. For temperature-related alerts, Yellow suggests potentially dangerous conditions for at-risk groups, Orange indicates very dangerous temperatures, and Red denotes extremely dangerous temperatures affecting all individuals.
