Australia’s east coast is set to be hit by a multi-day rain event, with forecasters warning flooding is “likely” as strong winds and waves hit the coast.
The wet weather event is caused by a deepening low pressure system that could last for up to eight days, Weathezone said.
A 2,800km stretch of the country – from Bateman’s Bay in southern New South Wales to Cooktown in far north Queensland – is on high alert.
The weather service says “total cumulative rainfall of 100-200mm is likely in parts of this region, with isolated falls greater than 300mm possible”.
Modeling suggests that up to 100ml could fall in 24 hours in parts of the NSW coast.
Heavy rains will begin on Friday before intensifying on Saturday, Weatherzone said.
“A low pressure trough will deepen near the east coast of Australia on Saturday, causing increased rainfall over parts of eastern New South Wales and QLD.”
“Rain is expected to continue over eastern QLD and large areas of eastern and central New South Wales on Sunday.
The location and strength of the Tasman Low becomes “uncertain from Monday”.
“The focus of heavy rain could be anywhere between the south and north coasts of New South Wales, with some showers also likely to extend west of the ranges.”
The low pressure system will also generate strong, potentially damaging winds” along the NSW coast and beaches from the weekend.
“These winds can trigger warnings on land and water, and will also generate large waves in the coastal area,” Weatherzone said.
