Argentina braces for 'Antarctic bomb' with extreme cold, snow, and wind alerts

Argentina is on alert as a powerful polar air front, colloquially termed an "Antarctic bomb," is set to sweep across the country, bringing a sharp decline in temperatures. While not official terminology, the phrase illustrates the dramatic impact of this cold air mass. The National Meteorological Service (SMN) has issued yellow alerts across several regions, warning of rain, snow, and strong winds.

The initial impact will be felt in eight provinces: Catamarca, Chubut, La Rioja, Mendoza, San Juan, Santa Cruz, Tierra del Fuego, and Tucumán. In Catamarca, yellow alerts are in place for rain and wind. Tucumán faces warnings for persistent rainfall, with potential complications in mountainous and vulnerable areas. Chubut and La Rioja are under alerts for intense winds, with sustained speeds of 40-60 km/h and gusts potentially exceeding 90 km/h.

More severe winter conditions are anticipated in the Andes. Mendoza expects moderate to heavy snowfall, with accumulations of 10 to 30 centimeters in higher elevations. San Juan, Santa Cruz, and Tierra del Fuego will experience a combination of snow and wind, which could disrupt travel on mountain routes. Reduced visibility is also a concern in these areas due to snowfall and gusts.

The SMN's yellow alert signifies meteorological phenomena capable of causing inconvenience or affecting daily activities. Residents are advised to stay informed through official channels and exercise extreme caution. Behind these immediate phenomena, a colder air mass is expected to progressively lower temperatures nationwide, bringing conditions more typical of the upcoming astronomical winter.
