It could literally be raining cats and dogs in Victoria on Thursday with the State Emergency Service warning people to tie down outdoor furniture, trampolines and even pets as winds of 100km/h sweep through.

The worst cold snap this winter will blast through the state over the next four days, bringing with it gusty winds, blizzard conditions and potential hail.

"With wind, the damaging effects there can be trampolines, furniture, even consider your pets in the rears of your gardens," warned Alistair Drayton, the State Emergency Services' deputy chief officer.

"It's about preparing yourselves, that's as I said before, even reducing the movement of things around the backyard, tying things down."
