Sydney weather to worsen this weekend after month of reprieve

A month’s worth of rain is forecast to fall over Sydney in the next five days, presenting a fresh flooding risk to some parts of the state just as NSW’s school holidays begin.

The city is forecast to receive at least 50 millimetres of rain per day from Friday to Monday, says the weather bureau, as temperatures hover between 11 and 19 degrees.

Although rain is predicted until at least next Wednesday, temperatures are expected to rise slightly, getting to 20 degrees on Monday and Tuesday.

Sydney recorded its coldest start to winter, failing to reach above 18 degrees for the first week of June.

The Bureau of Meteorology forecasts heavy rain for the Northern Territory, Queensland and the east coast of NSW this weekend, as a deepening low-pressure system moves in to end the dry start to winter.

The low-pressure system will also bring a return of the gale-force winds experienced in autumn, increasing the likelihood of dangerous weather warnings over the weekend.

For NSW, the bureau expects the heaviest rain to fall on the south and central coast. Weatherzone modelling suggests the region should brace for more than 100 millilitres in just 24 hours.

Given the potential for river rises and flooding in the event of consecutive heavy rain, the bureau advises school holiday travellers to “consider” their plans and monitor forecasts and warnings.
