These are photographs and a video I took of the sudden Melbourne hailstorm on 6th March 2010. 40mm of rain fell within an hour. Today was one of the main days of Moomba. From our apartment we could see the rides in the Alexandra Gardens. The sky suddenly blackened, and the lights of the ride were suddenly visible in the middle of the afternoon. Within a very short time the rides had all been closed and hundreds (thousand?) of people had to escape the enormous hailstones.
