An intense polar air front is set to begin affecting parts of Argentina within the next hours, with eight provinces expected to feel it first as rain, snow, wind and a sharp drop in temperature move across the country. Catamarca, Chubut, Mendoza, Misiones, Neuquén, Río Negro, Santa Cruz and Tucumán are in the first line of impact.
The timing is why the weather is drawing attention now. The Servicio Meteorológico Nacional is keeping yellow and orange alerts in place for different sectors of the country, and the change is arriving as many people are checking what the new ola de frío will mean for travel, school days and work routines. The alert map includes rain in Catamarca, persistent precipitation in Tucumán, strong winds and snow in Chubut, Neuquén, Río Negro and Santa Cruz, and heavy snowfall in Mendoza’s cordillera.
In the southern provinces, sustained winds are expected to range between 40 and 60 kilometers per hour, with gusts that could top 90 km/h in some areas. In Mendoza, snowfall is expected to be moderate to strong in the mountains, with accumulations of 10 to 30 centimeters in higher areas. The SMN said yellow level weather means phenomena that can cause problems or interfere with daily activities, a warning that fits a front expected to move quickly and hit several regions at once.
The dramatic phrase “bomba antártica” has also entered the conversation, but it is being used only as an illustrative way to describe the advance of an air mass of Antarctic origin, not as official SMN terminology. That distinction matters because the agency is framing this as a broad weather shift, not a label-driven spectacle, even as the forecast points to rain, snow, wind and persistent precipitation across different parts of the map.
What comes next is a colder air mass behind these systems, with specialists expecting a progressive drop in temperature across much of the country. The one thing the forecast does not yet pin down is how long the alerts will last, but the first wave is close enough that the next few hours are when the change will be felt.
