More than 670 calls for assistance have been recorded since late Wednesday, mainly for downed trees causing traffic and other hazards.

Most calls calls came from central Victoria, with 61 coming from the Frankston area, an SES spokeswoman said.

Overnight the strongest gusts of 124km/h were recorded at Mt Hotham and 119km/h at Mt William.

Closer to the city, Port Phillip Bay recorded gusts of up to 100km/h and Moorabbin Airport 87km/h.

A severe weather warning for damaging winds remains in place on Thursday for parts of the state.

Winds up to 90km/h are likely near the coast and elevated areas across the state's south and east, including the Grampians, the Otway Ranges and Strzelecki Ranges, the Bureau of Meteorology warned.

Areas that may be affected include Warrnambool, Wonthaggi, Morwell, Traralgon, Sale and Moe.

A blizzard warning is also likely to be issued, with up to 50cm of snow predicted to fall on Friday.

As winds ease across most of the state, the bureau's senior meteorologist Rod Dickson predicts temperatures will drop.

"Even though the temperature remains in the teens the wind chill is going to be quite significant, so it will feel significantly cooler than the advertised temperature," he said.

"We may even see some snow about the peaks of Mount Dandenong."

The SES is reminding people to keep clear of fallen trees and debris and ensure vehicles are moved under cover or away from trees, and loose items around the house are secured.

The wintry blast is the result of two strong cold fronts crossing through the state on Wednesday and Friday.
