Rain from Queensland central coast to Victoria brings soggy start to holidaymakers' week

Holidaymakers along the NSW coast would almost have wished they were back at work.

Drenching showers brought more than 125 millimetres of rain to parts of the South Coast on Sunday into Monday, with Moruya and Montague Island recording their heaviest falls in January since 1999, according to Weatherzone.

"There's one long system bringing rain from Queensland's central coast all the way down to Victoria and South Australia," Rob Sharpe, a meteorologist with Weatherzone, said. "All the places where people are enjoying holidays are pretty wet."

In Sydney, the rain forced multiple interruptions to the Third Test at the Sydney Cricket Ground. The West Indies added just 47 runs to their overnight total for the loss of a single wicket in a day with only 11.2 overs bowled.

By early Monday evening, Sydney had received more than 26mm of rain, bringing the two-day total to more than 40mm.

Flooding closed two of three eastbound lanes on Syd Einfeld Drive at Bondi Junction, while maintenance teams were also attending to flooding between Bondi Road and Oxford Street.

Lewisham was another area affected, with flooding at Railway Terrace, while traffic was also snarled at Liverpool Road in Croydon and Canterbury Road, Canterbury,

At least 14 Sydney beaches were closed due to massive surf.

The rain - and the prospect for more - prompted the Bureau of Meteorology to issue a minor flood warning for the Moruya Valley on Monday.

A flood watch was also in place for the mid-north coast between Newcastle and Port Macquarie, with minor to moderate flooding possible for the Lower Hunter, including Newcastle's central business district.

The bureau noted there was uncertainty about the focus of the heavy rain, but named the Karuah and Manning valleys as possible flooding areas, as were the Camden Haven and Paterson William regions.

The source of the rain was a slow-moving, low pressure trough that was drawing in moist tropical air from the north. The weather event was expected by the bureau to be the dominant feature for the early part of the week, with the eastern half of the state in for a soaking.

Tuesday is likely to offer longer dry spells for Sydney between the showers, the bureau said, adding, however, that another 20mm may fall in the city's rain gauges.

Conditions will ease on Wednesday as a high-pressure system builds but Saturday is set to be the next day of decent outdoors weather with the bureau expecting a mostly sunny day with a top of 27 degrees.

Those wanting guaranteed warmth by the coast needed to head to WA, where temperatures in Perth are expected to range between 36-39 degrees between Tuesday and Friday.

Some of that heat will finally make it to Sydney by early next week, when the mercury is expected to rise to the mid-30s, Weatherzone's Mr Sharpe said.
