Under the anvil from the storm entering the Yarra Valley. Just hearing the first rumbles. The bigger cells are tapping the shear and look to be rotating cyclonicly into the sea breeze.
Lots of chunky Cu sat under the anvil so firing nicely.
EDIT> now getting big booms almost continuous to our north
sea breeze is really getting sucked into the monster with the southerly picking up here. We should see northerlies push down through the Yarra Valley as the storms edge south and the trough deepens to our west.
