maritimeWind effect is frequent. Cold storm snow, dense maritime snow, and spring corn can occur within one trip.Public avalanche information
Chile DMC and Argentina SMN weather warningsNo single verified public regional avalanche bulletin covers this cross-border destination.Weather and flight context
Persistent westerlies and frontal systems create extreme windward-leeward precipitation contrasts.
- Severe wind
- Fast-moving frontal cloud
- Remote terrain and glacier flat light
Meteorological reference area
Patagonia South Andes catalogue locations
- Includes
- The published Futangue program area in northern Chilean Patagonia.
- Excludes
- Santiago, Central Andes, and Mendoza profiles.
- Elevation
- No verified operator-terrain elevation band is public. Each evidence value retains its site elevation.

Tier CModelled snowfall water equivalent176 mm SWE median · 131–217 mm interquartile range
- Site
- Futangue Park program base ERA5-Land grid cell · -40.3000, -72.2000 · 4.4 km from Futangue Park program base reference point
- Period
- Calendar years 1991–2020
- Completeness
- 360 monthly means; all 30 calendar years contain 12 values.
- Method
- ERA5-Land monthly mean daily snowfall accumulation was multiplied by calendar days and 1,000, then summed by calendar year.
- Limitation
- The Futangue program base is a named reference site. It does not define the complete flying or ski area. This unadjusted 0.1° reanalysis grid cell is not an observation, snow depth, or terrain-wide total. Grid elevation and wind redistribution can cause substantial local bias.

Monthly evidence
Each cell keeps its measurement type and unit. Reanalysis water equivalent is not snow depth. Text-only cells preserve a representative data gap.

Commercial operator assessment
Operator assessment process not independently verifiedThe operator must assess current snow, avalanche terrain, weather, aircraft limits, and rescue options. No private operational plan is inferred.
