Wild Weather Hits As 'Snow' Blankets Coastal Town

The full force of winter is expected to lash NSW again today as an intense rain band moves north.

Roads were turned into rivers overnight as Sydney was drenched by heavy rain.

Mosman in Sydney's north received 74 millimetres in the 24 hours to 8.30 am, the heaviest fall recorded across the city, while on the Central Coast, Gosford and Wyong copped 110 millimetres.

Backyards and carparks in Coffs Harbour turned white as tiny hailstones battered the coastal town.

Some excited residents claimed it was snow,  but the weather bureau has confirmed that the dusting was in fact tiny hail.

It was a busy night for SES crews, who received close to 100 calls for help, mostly for leaking roofs.

Volunteers are on standby again today with more heavy downpours expected.

"The main rain band is moving to the north of the city and to the hunter, but we will see some heavy showers coming in off the coast during the day," Bureau of Meteorology forecaster Kelen Kirkup told 10 daily.

There is also a chance of thunderstorms, mostly in the coastal suburbs.

With the heavy rain comes a warning for drivers, particularly during school pick-up and drop-offs. The SES is urging drivers to slow down and be aware of mud, debris, damaged roads and fallen trees.

The advice is to stay out of floodwaters, no matter the depth.

The rain is expected to hang around for most of Friday and to ease on Saturday before clearing just in time for Father's Day.

While the skies might be clear and blue in Victoria, Melbournians definitely felt the winter chill on Friday morning.

The temperature dropped to 2.3C just after 7 o'clock, the coldest morning in a year.

While the east coast has definitely felt the chill, the west managed to get a taste of summer this week, with Perth recording its hottest August day since records began.

Some suburbs reached 30 degrees.

But it looks like a soggy spring is on the way, with the weather bureau forecasting a wetter than average September in WA's southwest and western Tasmania.

The rest of the country will remain drier than average and warmer, which, combined with widespread drought, is expected to create a dangerous bushfire season.
