EC and CMC have upgraded a lot on the latest run with heavy falls in the east into central areas and multiple days of showers and storms. Heavy to very heavy falls in NSW and Queensland, potentially topping 500mm
Could cause substantial areas in the burn scar areas.
I struggle to think of such a long live blocking event with very humid easterly flow into a trough for 14 days give or take. A deep tropical depression or TC also looks like moving down into the Tasman Sea which will bring down some deep tropical moisture and push big swells onto the NSW coast.
EDIT> looking at EC it’s got widespread though scattered showers and storms today and tomorrow. Falls are patchy, but locally heavy. Cells make it into the Melbourne metro area, so might be a chance. Best of it near and north of the ranges.
