Overview
Four stations listed as operated by YAA, with data for three others from Yukon Government departments: established primarily to provide near-real-time information relating to avalanche risk. Unfortunately only three stations record any snow-related metrics.

• YAA Mt Anderson, Wheaton Valley (YAAAND)
• YAA Fraser (YAAFRA)
• YAA Haines Pass (YAAHP)
• YAA Summit Creek (YAASUM)
• YG Hwy Fraser Highway Camp (HWYFRA)
• YG Hwy Mount Racine (HWYRAC)
• YG Wildland Fire Mgmt Mount Sima (SIMA)

Limitations and strengths for application
Not clear that data are available: no quality-control details provided

References
None available

Link to download data (and format)
Not clear if YAA data are archived or publicly available: seven-day plots on YAA web site, but not all are functioning (those for HWYRAC, YAAHP and SIMA appear to operational as of Sep 2021: YAAAND and YAASUM seem to have major errors: no data shown for others).
Data from YG-operated stations is publicly available on request, but with no guarantees as to response-times.
