Hail Report Information
Station Number: CAN-QC-69
Station Name: Frelighsburg 10.3 E - Mount Pinnacle Land Trust
Date: 5/21/2022 5:57 PM
Submitted 5/22/2022 4:08 PM
Taken at registered location: True
Notes: Heard large hail clapping off west and south facing windows in rhythm with moderate wind gusts around 6 PM shortly after the beginning of torrential downpour. Thought it was panicking small birds or junebugs hitting windows at first. Hail was embedded in relatively warm rain and rapidly melted after hitting the ground. No hailpad data, but I suspect that water around stones would have cushioned any indentation. Gauge data checked around 6:30 indicates downpour generated approx 10 -11 mm of precip in 4 minutes, for rain rate of Photo with ruler showing frozen part to be 3/8" diameter; it appears that smaller stones melted in the downpour. Estimate that maybe 1%-5% of water content was frozen, although it could be lower considering the soft, watery texture. I suspect that the system was dissipating rapidly and no longer producing hail and shedding the last of its hail. Power went ~6:20PM shortly after due to widespread power outage extending along the border south of Sutton from Pinnacle through Missisquoi Valley. Timing and Hydro-Quebec outage map is consistent with this storm damaging the major power line along Route 139 just south of Sutton (not the first time this has happened). Power came on again ~1AM, but scattered local power failures remained until Sunday afternoon between Chemin des Erables, Richford Rd., and in Sutton Mountains.
