A rare cloud occurrence called a Fallstreak Hole sighted in Eastern Victoria, Australia 😮 It is a large gap, usually circular or elliptical, that is formed when the water temperature in the clouds is below freezing, but the water, in a supercooled state, has not frozen yet due to the lack of ice nucleation. -Wildaware #Giveaways
