AFLW fans should expect to get soaked on Saturday afternoon, but Sunday's Formula One Grand Prix should be mostly dry.

Flooding in regions will recede and Sydney will warm up over the weekend.

It’s the second day of wild, wet weather for parts of NSW, with more than 200mm of rain expected to hit some towns in 24 hours.

While rain is forecast for Sydney, the weather bureau says the city will escape the worst of the weather.

Parts of the NSW central coast and up into the Hunter are in line to receive "quite intense rainfall" with the potential to cause flash flooding.

The burst of late-season heat that seared south-eastern Australia over the weekend will give way to days of heavy showers for Sydney.

Marcus is expected to pass off the coast of far-north Western Australia after dumping more rain on the Kimberley region.

Sydney's late-season heatwave is on course to deliver the city's hottest trio of March days since 1902, with another burst of warmth on the way.

Temperatures in the city were nearly 10 degrees hotter than the March average by early Sunday afternoon.

There's little relief in sight for the city, with 39 degrees predicted for the CBD and most of the greater Sydney region.

Parts of Sydney have had their biggest dump of rain in five years, helping to soak gardens still dry after a prolonged spell of below-average falls.
