Andean snow and precipitation patterns

Overview

An Antarctic air mass brought extreme cold, strong winds, and mixed precipitation to Argentine Patagonia in early September. This weather system triggered a cold front across the mountain and steppe regions, with wind gusts exceeding 70 to 80 km/h in areas such as Tierra del Fuego and southern Santa Cruz.

Following these weather patterns, significant snow accumulation in the Andes is expected to impact water resources in Argentina and Chile. In San Juan, Argentina, experts have characterized the snow levels as a “historic event,” prompting warnings regarding potential rapid snowmelt. Similarly, in Chile’s Coquimbo Region, recent precipitation and snow have reversed a seven-year trend of low river flows, with regional reservoir levels reaching 56% capacity by late August.
