The Bureau of Meteorology has forecast a wet Friday with upwards of 25mm and the possibility of a shower or two on Saturday.

Of the three days, Friday’s weather looks the worst with a low pressure system sweeping across South Australia, Victoria, and New South Wales.

The worst weather is due around midday in Melbourne on Friday with the possibility of thunderstorms with potentially strong gusts and heavy rain.

The high winds that precluded MotoGP from holding its sprint on Sunday last year aren’t expected to return.

So bad was the forecast in 2023 that organisers brought the grand prix forward to Saturday.

Sunday’s postponed sprint was eventually cancelled due to high winds, but a repeat looks unlikely at this stage.

The Bureau of Meteorology has tipped a windy Saturday but blustery conditions should die down on Sunday.

MotoGP will headline the Australian Motorcycle Grand Prix with support from Moto2, Moto3, and Oceania Junior Cup.

Saturday’s sprint gets underway at 3pm AEDT with Sunday’s grand prix set to start at 2pm AEDT.
