Heavy rain and high winds are forecast for a cold weekend in multiple states.
“By definition, ECLs produce any combination of damaging to destructive winds, heavy rainfall, flooding, or powerful, erosive surf, with the most severe ECLs producing all four together,” Weatherzone said.
The last east coast low to affect Australia formed in July 2022.
Weatherzone said the advancing low was expected to form on Sunday afternoon and “rapidly strengthen” overnight into Monday.
Some models suggest the low could continue to strengthen into next Tuesday.
Although it is not certain, it is believed that the south coast of NSW and north-east Tasmania will be the most affected.
“However, heavy rainfall, damaging winds and heavy surf are possible all the way from Newcastle and Sydney in New South Wales to East Gippsland in Victoria and down the coast (of Tasmania) to Hobart,” Weatherzone said.
“Historically heavy rainfall has also moved inland into Canberra and the Snowy Mountains (where it may fall as snow as in July 2020 – when a system brought snow from a less common easterly direction).”

Heaviest rainfall from the lowest is likely to reach 100-200mm, with isolated pockets of 250mm or more.
Gusts of up to 120 km/h are also expected, along with potential waves of up to seven metres.
