Snow and 90 km/h (55 mph) winds suspend ALMA observations in the Atacama Desert, Chile
A new snowfall accompanied by winds of 90 km/h (55 mph) reached the Chajnantor Plateau in Chile’s Atacama Desert on August 18, 2026, keeping astronomical observations suspended at the Atacama Large Millimeter/submillimeter Array (ALMA). The antennas remained in survival mode as winter weather continued to affect high-altitude roads, border crossings and communities across northern Chile.
