Overview

• Authorities report roughly 50 cm of snowfall between Punta de Vacas and Las Cuevas on the Argentine side and about 70 cm at Chile’s Los Libertadores complex, with whiteout conditions and gusts reported up to 77 km/h in Neuquén.
• Vialidad Nacional restricts travel to Uspallata on Route 7, which is intransitable from there to the international tunnel due to heavy snow and rockfall.
• Multiple Argentina–Chile corridors are closed, including Cristo Redentor, Cardenal Antonio Samoré, Pino Hachado and Pehuenche, while Icalma, Hua Hum and Mamuil Malal operate under limited hours and strict requirements.
• Road crews and Gendarmería deploy machinery for clearing and shoulder widening, with tracked vehicles assisting high‑mountain communities, and officials insist on chains, warm clothing and supplies for anyone traveling.
• Forecasts indicate gradual improvement from Saturday, though severe cold could slow de‑icing, and officials urge travelers to check @UPFronterizos and @CFLosLibertador for status updates.
