Fallstreak Hole: Stunning Rare Hole Punch Cloud Seen Twice This Week in British Columbia



















According to The National Weather Service: High to mid level clouds ... are often composed of tiny water droplets that are much colder than freezing, but have yet to freeze. These 'supercooled' water droplets need a 'reason' to freeze, which usually comes in the form of ice crystals. Planes passing through the cloud layer can bring these ice crystals. Once the ice crystals are introduced, the water droplet quickly freeze, grow and start to fall. A hole is left behind, which will start to expand outward as neighboring droplets start to freeze.
