Tens of thousands of fans are expected to line the streets of Melbourne for the AFL grand final parade despite the terrible weather forecast.
The AFL will leave it to the last minute to decide if the parade will go ahead at noon (AEST).
It is the last chance for fans to see Hawthorn and Sydney players before tomorrow's season decider at the MCG.
AFL chief executive Andrew Demetriou says there is a chance the parade will be cancelled.
"Obviously if the rain's too heavy and there's hail, then that makes the parade difficult to proceed, but all the players want to participate," he said.
"We've got several options to make it work, but if it was too heavy then you couldn't have the players out in the parade."
The parade starts at the Arts Centre on St Kilda Road and finishes with a presentation on the steps of the Treasury building.
