Further to my post on Thursday about the nasty looking bow echo near Wyong, I also noted an interesting feature on the windfinding radar from this storm. Have a look at the main part of the storm near Mangrove Mountain and note the moving black dot that is embedded in the storm - could this be indicative of a tornado?
I haven't seen any news reports but it is a fairly isolated area up there.
