The National Meteorological Service (SMN) is the official body responsible for collecting, analyzing, and disseminating meteorological information in Argentina. Its primary functions include predicting weather patterns, issuing early warnings for dangerous phenomena, and providing climate data for various activities such as aviation, agriculture, and navigation.

The SMN operates using a network of meteorological stations across the country, supplemented by satellite imagery and numerical prediction models. The service defines a meteorological alert as the "possible occurrence of a meteorological threat," issued to support public decision-making. These alerts are typically issued 24 to 72 hours in advance, while short-term advisories (ACP) urge immediate action for phenomena that may occur within minutes of issuance.

Alerts can be issued for various conditions, including rain, storms, extreme temperatures, or other unusual weather events. The SMN categorizes alerts into levels: yellow indicates possible damage and temporary disruption; orange warns of dangerous phenomena posing risks to society, life, property, and the environment; and red alerts signify exceptional phenomena with the potential to cause emergencies or disasters.
