It was unusual weather yesterday - the thunderstorms early in the afternoon were being created by the CBD. But by later in the afternoon they were general across the city.
I have posted before that I have concerns about the way these guys operate. I've seen them land off the DZ in the past - on the beach near Elwood life saving club. I've also seen them emerge from cloud, under canopy, very close to the C182 out of Williamstown.
