Watch for storms and 100 cm bases.....

Those seasonal forecasts can be done as accurately by monkeys throwing darts, especially when there is no El Nino or La Nina.
Regardless of the forecasts, do not commit $$$ until adequate snow is on the ground. AFAIK Portillo has not had a season since 2009 that exceeded its 1971-2007 average.

That's sobering. Is that an anomaly or true for South America in general?
It is likely true for the latitude 33-35 areas Portillo, Valle Nevado and Las Lenas. Farther south the climate is different. It's a wetter and less boom or bust climate, but altitude is much lower so you have to worry about the rain/snow line.

LOL
Portillo is bringing its average snowfall down to 200" or so at the resort level. You have to commend them for honest reporting.
But where did 100" disappear to? Global Warming is changing weather patterns?

My previous two trips to South America were more at the last minute, and I paid a bit more in airfare, but that's okay with me. Lodging and skiing are the same price.
I paid $1k instead of $700 for a round trip, which made the difference between exceptional snow and average snow.
I believe the climate models forecast drying out in some places at those latitudes. Portillo, despite its altitude, is an outlier in latitude at 32.8. Compare to lowest latitude ski areas in North America, Ski Apache NM at 33.4 and the rarely open Mt. Lemmon AZ at 32.4. Valle Nevado is 33.4. Las Lenas latitude is 35.1, similar to Arizona Snowbowl at 35.3.
I have high skepticism of climate models' regional predictions even though the big picture projections of overall world temperatures have been in the ballpark long term. We have covered this ground before. Since 2021:
Portillo had another lean year in 2022, 163 inches
256 inches in 2023 was about average but with only 72 inches by Aug. 13 it was not a good season overall.
261 inches in 2024 was also close to average but qualitatively better since 223 inches had fallen by June 25.
Some other updates to that post from 2021:
1) Alyeska had another excessively rainy season in 2024-25. The ratio of mid to upper snowfall was 52%, fifth lowest since 1979 and all of the other four were since 2015.
2) L.A. rain and SoCal snow were high in 2022-23 and 2023-24, but neither season met the standards of 2010 and prior excellent seasons since there was not much natural snow before February. 2024-25 in SoCal was only marginally better than the abysmal 2013-14 and 2017-18 seasons.
3) Taos had average seasons in 2022-23 and 2023-24 but its second driest ever season in 2024-25.
4) Utah has rebounded impressively. After one more below average season in 2021-22, it had record high snowfall in 2022-23 and the past two seasons were above average.
