In this mornings forecast, the BoM are still sticking to their guns, and still going for 150mm - 250mm on Wed.

Looking at the pressure systems, we should have NE winds today,- E tomorrow & SE on wednesday. Pretty much onshore flow.

WZ, and some others are far more pessimistic. But until wednesday comes and proves them wrong,- who knows ??
Maybe when the change of shift bundy on this morning, they may take stock of things, and change it all.
