Southeast Australia to be hit with week of rain as Autumnal conditions take hold

Autumnal weather is beginning to take hold across Australia’s southeast.

The Bureau of Meteorology (BOM) predicts a deep low pressure system and a cold front moving across the region will bring “thunderstorms, rain, windy conditions and abnormally high tides” over the weekend.

The weather system is expected to cause downpours in Melbourne, Adelaide and Hobart for most of, if not all, of the coming week.

BoM meteorologist Christie Johnson said the weather system is expected to move East from Western Australia and join with a colf front sitting over the South Australian coast on Saturday.

“We’ll see showers and thunderstorms extending across (SA),” Johnson said.

“The storm risk does extend across most of South Australia and also into the far west of New South Wales and north-western Victoria as well.

“On Sunday, that system is going to make its way across NSW, Victoria and Tasmania.”

The system is expected to spark thunderstorms stretching from “southern Queensland down through inland parts of New South Wales and into Victoria”.

It’s expected to bring some relief to a recent stretch of dry conditions to parts of NSW and Victoria, while also whipping up swells across coastlines as it enters the Bass Strait.

Hotter-than-usual temperatures are also expected to come to an end as the cold front follows the low pressure system.

“Our overnight minimum temperatures tonight could well be up into the low 20s in some areas, and that could see some May records fall, and maximum temperatures tomorrow up into the mid 30s,” Johnson said.

“In some cases, high 20s could also see some new records being set during Saturday.

“The cold air will make its way right across the southeast, with much cooler temperatures.

“And this will feel particularly cool, particularly given the warm temperatures we’ve had recently.”
