Black Sea moisture and continental air interact across a very large, high-relief range.
- Mountain cloud
- Strong wind
- Large forecast and observation gaps
Meteorological reference area
Caucasus catalogue subregions
- Includes
- Published Caucasus subregions outside the dedicated Svaneti profile.
- Excludes
- Svaneti destination 19 unless a source explicitly spans both areas.
- Elevation
- No verified operator-terrain elevation band is public. Each evidence value retains its site elevation.

Tier CModelled snowfall water equivalent — Central Caucasus reference544 mm SWE median · 504–581 mm interquartile range
- Site
- Central Caucasus reference ERA5-Land grid cell · 42.6000, 44.2000 · 5.3 km from Central Caucasus reference 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
- This reference area supports evidence discovery and comparison. It is not an operating-area or tenure boundary. 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.

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.
