Black Sea moisture and continental air interact across a very large, high-relief range.
- Mountain cloud
- Strong wind
- Large forecast and observation gaps

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.

- Site
- Caucasus catalogue subregions
- Period
- 1991–2020 standard normal sought; evidence review completed 2026-08-25
- Completeness
- No representative series passed the geographic and elevation review.
- Method
- Official station, snow-network, gridded, and operator sources were screened. No estimate is calculated from a broad centroid.
- Limitation
- The gap concerns comparable mountain evidence. It does not mean that local observations or operator records do not exist.

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.
