SES still responding to hundreds of calls for help

Victorians have been warned windy conditions will continue this week as emergency crews clean up after Tuesday's wild weather.

The SES received more than 3200 requests for assistance since midnight.

Crews are focusing on the clean up on Wednesday after the severe weather warning was cancelled, the SES said.

But despite the winds slackening, emergency services continue to urge Victorians to stay clear of coastal areas with the weather expected to worsen later in the week.

Bureau of Meteorology forecaster Kevin Parkyn said the intense weather system affecting the whole state would hit Victoria only once every few years.

"We're in for a windy week, so it's not over yet, although we have seen the most intense winds for the week," Mr Parkyn said.

A man, 51, has been airlifted to hospital after a brick wall collapsed in strong winds south of Sydney.

Emergency services were called to Cavendish Street at Mittagong in the Southern Highlands, after midday on Wednesday.

It appears the man was in a car park when a rear wall collapsed and caused him to fall down an embankment at an industrial complex.

Paramedics said the man was flown to Liverpool Hospital in a serious but stable condition.

He suffered head and chest injuries after being trapped for about an hour.

A crime scene has been set up and Work Cover will be investigating.

A Victorian woman was injured in another wall collapse yesterday, just a day after a Melbourne father-of-two wall killed in a wall collapse at a construction site.

A violent winter storm blasted Victoria, leaving several people injured, trees toppled on cars, buildings damaged, snow in alpine regions and more than tens of thousands of homes without power across the state.

Meanwhile, NSW has been hit by gale force winds for the second day running, as emergency services already respond to almost 1000 calls for help across the south of the state.

The Bureau of Meteorology says winds on the Alpine peaks may reach 80km/h with gusts to 120km/h.

The Snowy Mountains is expecting blizzard conditions above 1200 metres.

SES spokesman Phil Campbell said the SES had received 994 calls for help since Tuesday.

Most of the calls were from the Illawarra, Wollongong, the Southern Highlands and the Blue Mountains.

The calls were mostly for property damage or fallen trees, he said. No injuries have been reported.

About 20,000 homes and businesses were left without power after the winds struck on Tuesday.

Severe weather warnings for the Hunter, South West Slopes, Riverina and ACT forecast districts have been cancelled, but the situation will continue to be monitored and further warnings will be issued if necessary.
