Residents along the East Coast are being warned of hazardous surf over the weekend as a powerful Tasman swell is predicted to see wave heights of up to 15 metres.
Beaches exposed to a southerly swell will see the greatest risk of erosion and high tides.
Sky News Chief Meteorologist Tom Saunders said a low-pressure system will rapidly deepen off the west coast of New Zealand through Thursday and Friday, generating a “long fetch of gale-force southerly winds” through the Tasman Sea.
“Which will rapidly then cause the swells to increase along the New South Wales and Queensland coastline,” he said.
Hazardous surf warnings are likely to be upgraded to damaging as the peak of the Tasman swell arrives.
Flash flooding, damaging winds to move through northern NSW coast14/12/2020|4min
The worst of the weather which has battered south-east Queensland and the far North Coast of New South Wales is starting to move further south with warnings of flash flooding, damaging winds, and damaging surf.
Sky News Chief Meteorologist Tom Saunders said the extreme weather battered Byron Bay which saw “significant coastal erosion” as well as waves up to 12 metres in the region.
The NSW-Queensland border saw 739mm of rain over the past four days, while wind gusts in the area reached up to 104km.
The rain and wind are now beginning to move south prompting a cancellation of the flash flooding warning for Queensland.
