NSW and Queensland face another day of damaging waves, winds and rainfall, with weather officials warning of further flooding and coastal erosion.
A low-pressure system off the coast of southeast Queensland bringing massive rainfall and cylonic winds combined with a seasonal high tide to wash away much of Byron Bay’s Main Beach.
The Bureau of Meteorology (BOM) warned on Monday that the coastline on NSW’s Mid North Coast was at risk of similar erosion, perhaps as far south as Newcastle.
The BOM urged residents of northern NSW to be ready for dangerous conditions on Monday evening and Tuesday morning, warning the weather would not relent until later on Tuesday.
A severe weather warning was issued on Monday afternoon for the Northern Rivers, parts of the Mid North Coast and the Northern Tablelands, between Tweed Heads and Taree.
A hazardous surf warning embraced a large swathe of NSW, taking in the Byron Coast, Coffs Coast, Macquarie Coast, Hunter Coast, Sydney Coast and the Illawarra Coast.
There was a moderate flood warning for the Orara River, a minor to moderate warning for the Bellinger River, and minor warnings for the Tweed, Wilsons and Nambucca Rivers.
Southeast Queensland received a reprieve on Monday afternoon after earlier experiencing tropical cyclone-like conditions. The damaging winds and heavy rainfall eased up by evening, but surf and tide conditions are still dangerous.
Authorities were still warning of hazardous surf conditions, and possible flooding from Fraser Island to the NSW border on Monday evening.
The damage to storm-lashed beaches could be lasting, with Surf Life Saving NSW warning that the giant waves could create new, permanent rips at beaches previously considered to be safe.
Sites in NSW’s Northern Rivers District had about 400mm of rain in just a few days, and some locations near the Queensland-NSW border were inundated with 180mm of rain on Sunday.
