"Friday into early Saturday is the most reliable stretch of the forecast, and the guidance is converging well on the timing of a Chile-centered storm even though snowfall intensity still varies from model to model. Valle Nevado, El Colorado, La Parva, and Portillo should do the best in central Chile, with current resort totals ranging from 8-22 cm."
"Nevados de Chillán carries the best snowfall signal through the weekend, but by Saturday night into Sunday the guidance starts to diverge more sharply on a second wave for the Chilean volcanoes. The first pulse Friday is well supported and already supports 17-23 cm through Saturday at Nevados de Chillán, with snow levels mostly 1,300 to 2,000 meters and dense snow favored by SLRs around 5-8."
"Snow levels mostly hover between 2,200 and 3,000 meters during the steadiest precipitation, so the cleanest snow should stay on upper-mountain terrain, especially at Valle Nevado and La Parva, while lower terrain at El Colorado and Portillo may run denser or mix early."
A major snow event impacts South America from Friday through Saturday, with Nevados de Chillán leading precipitation at 17-23 cm and central Andes resorts receiving 8-22 cm. Friday into early Saturday represents the most reliable forecast period with well-aligned model guidance on storm timing. Central Chilean resorts including Valle Nevado, El Colorado, La Parva, and Portillo expect 8-22 cm, while Las Leñas receives 7-11 cm. Snow levels range between 2,200-3,000 meters during peak precipitation, with upper-mountain terrain receiving cleanest snow. Snow quality appears moderate with snow-to-liquid ratios of 8-12 at higher elevations and 4-7 lower down. Wind gusts reach 40-50 km/h on exposed ridges Friday afternoon and night. A secondary system may affect southern Chile Sunday with lower confidence.
