Melbourne, Adelaide, Hobart weather: Heatwave to mar Australia Day weekend

IF YOU think it’s hot and humid now, just wait for the long weekend when temperatures across the country are set to soar.

Heatwave set to hit south-east Australia over the long weekend

A BLISTERING heatwave is set to smash Australia’s southeast for the second time in two weeks with warnings the worst of the hot weather isn’t over yet.

South Australia, Victoria and Tasmania are set to cop the worst of heat with soaring temperatures predicted across the Australia Day long weekend.

Heatwave conditions which smashed South Australia last week are back, with a high-pressure weather system forecast to bring more of the same sweltering conditions.

The Bureau of Meteorology said the air mass that brought temperatures in the mid-40s to some regional centres last week haven’t dissipated and it’s going to heat up even more yet.

Several councils have already rescheduled family and children’s Australia Day events with temperature set to hit 38C in Adelaide.

Wineries taking part in the Adelaide Hills Crush Festival have also cancelled about a third of 50 planned events, the ABC reported.

The one-day international cricket match between Australia and England at Adelaide Oval will go ahead as normal.

The State Emergency Service has warned all South Australians participating in sporting events and festivals over the long weekend to be proactive and keep themselves safe.

Last week’s hot blast resulted in 150 people going to hospitals over the three days with another 40 people admitted for specific heat-related illnesses, SA Health spokesman Paddy Phillips said.

Extreme conditions are also forecast for northern parts of Tasmania from tomorrow while a severe heatwave will extend further into southwestern NSW.

The good news is cooler conditions should bring some relief from Tuesday.

BOM meteorologist Sarah Fitton said temperatures were increasing across the southeast and would culminate in oppressively humid conditions for the Australia Day long weekend.

Ms Fitton said hot days and hot nights would lead to the severe conditions developing and this could reach coastal areas.

The heatwave is also extending across most of Victoria.

Southerly winds will keep Melbourne at a cooler 30C, however the rest of the state is in for a few humid days.

Saturday and Sunday are tipped to be even warmer as the heat moves further south.

“Temperatures will be 14 to 18 degrees above average and central parts of Tasmania could even see temperatures in the mid- to high-30s,” Ms Fitton said.

“Adelaide is forecast to hit 42 degrees on both Saturday and Sunday. Melbourne will have its hottest day on Sunday as it approaches 40 degrees and Hobart should reach the low-30s.”

Ms Fitton said minimum temperatures will also be up across the weekend and would bring little overnight relief.

“And on top of this heat, tropical moisture feeding down from Queensland will increase humidity during the weekend, particularly through Victoria and Tasmania,” she said.

The rest of the southeast will also remain warm with the BOM on Monday warning temperatures across inland NSW will stay above 40C for most of the week.

Hot weather and heatwaves aren’t unusual at this time of year.

Ms Fitton said the high humidity levels were unusual though because drier conditions were much more common for southern Australia during heatwaves.
