A very interesting afternoon/evening here on the Gold Coast. Un-fortunantly i have no pics but this afternoon we got a nice but quick storm move over had nice mammatus and showed some interesting features but by the time i found my phone it had started raining lol. It was mainly a heavy downpour where i live but a little to my south west (mudgeereba/gilston/worongary) I was told it hailed quite heavily only pea sized hail thankfully. And another small cell moved over us around 6pm again quite quickly with a couple of cloud to cloud flashes (no visible cg that i could see).
Quite interesting for this time of year! The cell this afternoon gave off some wierd sounding thunder, where we are its usually a sharp but booming sound this time it was a low but loud 'growl'(for lack of appropriate wording lol) kinda like what you hear on those corny 80's horror movies.
