More wild weather is expected in Victoria and New South Wales today after gale force winds swept across the states yesterday.

More than 300 SES volunteers worked through the night attending 144 calls for help across NSW with trees down and roofs damaged.

The worst-affected areas are metropolitan Sydney, the Illawarra and Hunter regions.

Wild winds lashed parts of the state yesterday, leaving about 1,200 homes and businesses without power.

There is a severe weather warning this morning for damaging winds in Sydney, Illawarra, the South Coast, and the Central and Southern Tablelands, while blizzards are forecast for the Snowy Mountains.

Police have issued a warning for motorists to take care during the unpredictable weather conditions.

Meanwhile, more than 7,000 households remain without power across Victoria, after gale force winds damaged powerlines and caused widespread damage yesterday.

The Bureau of Meteorology says it expects to issue severe weather warnings for Victoria for the remainder of the week, but the fiercest winds are thought to have passed.

Bureau forecaster Kevin Parkyn said the intense weather system affecting the whole state hits 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.

Victoria's SES received more than 3,000 calls for help on Tuesday, with more than 34,000 homes without power at the height of the storms.

A Melbourne woman was lucky to escape serious injury when she was struck by roof sheeting, while another woman was injured when a brick wall collapsed in Yarraville and several drivers were hurt by trees falling onto roads and their cars.
