Sydney weather: Week-long rain event strikes – what you need to know

Heavy rain will hit large parts of Australia’s east and west coasts this week, bringing an abrupt end to the balmy spring weather.

A combination of troughs and low pressure systems will bring rain and potential flooding to New South Wales, and Sydney will remain wet for most of this week.

The port city is expected to receive 15mm to 30mm of rain every day this week from Tuesday, before rainfall increases over the weekend.

A spell of warm weather in Sydney ended on Monday, with maximum temperatures struggling to rise above 20 degrees Celsius.

Showers and thunderstorms will also develop over western regions of Western Australia before spreading south and east between Tuesday and Thursday.

Total rainfall in the west and south-west of the state is expected to remain below 10 mm; However, in some areas in the far southwest, accumulated totals will be between 15 and 50 mm by the end of the week.

The wet conditions could provide some much-needed relief for many on the West Coast. This comes after parts of Perth and Bunbury suffered their driest seven-month spell on record.

“While there won’t be enough rain to completely eliminate the precipitation deficits of the past seven months, the wet weather will be a welcome change to the parched landscape,” said Ben Domensino of Weatherzone.

The meteorologist said most forecast models agree heavy rain will hit parts of eastern, western and central NSW and southern Queensland.

“Weather patterns like this could produce hundreds of millimeters of rain along the NSW coast and adjacent areas,” he said.
