A powerful polar wave began affecting Argentina on June 23, 2026, hitting the southern provinces of Neuquén and Río Negro with particular severity. For foreign readers, this region is known as Patagonia, the vast southernmost tip of South America famous for its glaciers and mountains. The current weather brings extreme temperatures, heavy snowfall, and intense winds, creating a true "winter combo" that has put the population on high alert.
The National Meteorological Service (SMN) has issued a yellow alert for extreme temperatures. This alert covers Buenos Aires (CABA), the capital city, and 15 other provinces including La Pampa, Mendoza, San Luis, Córdoba, San Juan, La Rioja, Santiago del Estero, Salta, Jujuy, Santa Fe, Entre Ríos, Corrientes, Misiones, Formosa, and Chaco. However, the impact in Patagonia remains the most severe.

Amidst this polar wave, the city of La Plata (near Buenos Aires) is facing a CNG (Compressed Natural Gas) shortage lasting 13 days. CNG is a common fuel for vehicles in Argentina. Only 6 out of 45 gas stations have firm supply contracts. The supplier, Camuzzi, has limited sales to 1,000 m³/day per station. Taxi and remis (private hire) drivers are protesting at key intersections like 7 and 50, Plaza Moreno, and the Government House.
Gas demand reached 174-178 million m³/day, while national production covers only 140 million m³/day, with imported LNG adding 18 million m³/day.
