Authorities are pleading with people living or camping along the Murray River in Victoria's north to stay away from creek and river banks as severe weather again lashes the state.

A cold front moving into the state will see northerly winds continue to strengthen overnight and a severe weather warning for damaging winds is current for southern and mountain districts.

The winds will average around 50–60 kilometres per hour with peak gusts of 90–100kph.

Wind gusts of 89 kilometres per hour at Wilsons Promontory in the state's south-east and 85 kilometres per hour at St Kilda, in inner Melbourne, have already been recorded.

Almost 100 large trees have fallen into the Murray River between Cobram and Yarrawonga, creating hazardous water conditions and a danger that the ground along the river bank may collapse without warning.

People are being urged to avoid walking, camping or driving in the area.

"We've had a long duration flood event at this point in time," the State Emergency Service's Wayne Roberts said.

"That's undermined the integrity of some of the river banks, so getting in close proximity of those riverbanks is a potential for either a minor collapse of the bank or to actually slip just due the fact that there's a lot of mud there."

Richard Carlyon, a senior forecaster at BOM, said windy conditions would peak overnight with wind gusts of 90–100kph in the Melbourne area.

Last Sunday, thousands were left without power, more than 2,800 trees were blown down and more than 1,300 buildings were damaged in winds of up to 110kph.

"I don't think this system will be quite strong," Mr Carlyon said.

"But it's certainly at the low end of damaging scale and something to be wary of."

Mr Carlyon said the forecast winds were at the "low end of the damaging scale".

"It wouldn't be a surprise to see some trees come down in this scenario," he said.

"The winds are moving in from the north, a similar direction to what happened last weekend, but not quite as strong."

Despite having a taste of spring the past few days, the weather will turn cold once again on Tuesday.

"[The cold front will] bring some cold air up from the south-west and we're likely to see max temps in the mid-teens on Tuesday with snow down to 900 metres," Mr Carlyon said.

"That is part of the normal spring cycle, a sprinkling of warmer and colder days.

"We're starting to see a few warmer days now that we're getting into mid-October though."

More than a dozen flood watches and warnings remain in place for northern parts of Victoria.
