Severe weather warnings for damaging winds remain in place for parts of NSW, Victoria, Queensland, SA and the ACT as of Tuesday.

The Bureau of Meteorology (BoM) advises a very cold and windy air mass will remain over the region for the next 24-48 hours after the cold front moved offshore into the Tasman Sea.

BoM senior meteorologist Jonathan How urged people to be vigilant around strong winds "because trees are so weak, particularly across the East Coast".

"We will continue to see those damaging winds along the east coast of about 90 kilometres an hour, potentially reaching up to 110 kilometres an hour, about some of those elevated areas," Mr How said in a Bureau video.

Strong to damaging winds will continue for much of Tuesday but are expected to gradually ease in SA into the evening.

Damaging winds are also likely to develop about the southern Victorian coastline during Tuesday night, potentially impacting Melbourne as well.

Sharp, sudden increases in wind speeds will persist along the east coast and ranges into Wednesday, easing from the north in the morning and elsewhere by the evening.

The coldest air will move over south-eastern regions during Tuesday afternoon and evening, with the snow level falling to as low as 600-800 metres for NSW, Victoria and Tasmania.

Significant snow accumulations are likely, and light snow is possible around the Grampians, Yarra Ranges and Central Tablelands on Tuesday evening.

There have been reports of 15-20cm of snow about the Alpine resorts, with more snow, and blizzard conditions forecast.

IN OTHER NEWS:

Further widespread showers and isolated storms will bring small hail, although significant further rainfall totals are not expected.

Large wave and swell conditions will impact most of the southern mainland coast. Parts of the coast could see tides near or above High Astronomical Tide (HAT).

Temperatures have dropped significantly with the front as cold air moves up from south of the country. Strong winds have made the 'feels like' temperature much lower.

Wind and showers will ease late Wednesday and into Thursday as a high-pressure system moves in. It will remain cold however, despite some sunshine returning.

These calmer conditions will be short-lived, as another cold front moves across the southeast from Friday, with further cold air behind it.

While this system will bring more cold and snowy conditions, it will not be as windy.
