Severe NSW storms move north

The worst of Sydney’s wild weather is over but monster waves and flash flooding remain a threat along the NSW coast as the storms that lashed southern areas make their way north.

The clean-up job in the state’s south is continuing, with State Emergency Service (SES) volunteers still responding to some of the 1400 calls they received since the severe weather hit late on Monday.

The Bureau of Meteorology (BOM) has gale warnings in place between Point Danger and Crowdy Head near Port Macquarie and nine-metre waves are expected to pound the coast.

A spokesman said the strong winds weren’t expected to ease across most of the state until Thursday.

“The system that led to the wind changes has moved offshore,” meteorologist Andrew Haigh told AAP on Wednesday.

“The worst of it is certainly finished.”

The low-pressure system responsible for the rain and the wind had moved to the north coast overnight and was near Lord Howe island by Wednesday afternoon, he said.

SES spokesman Phil Campbell said emergency workers were still working through a backlog of requests for assistance, especially near the hard-hit Illawarra region and Sydney’s coastal suburbs. A few new calls were coming in from the north coast, he said.

The SES was more concerned about a dangerous combination of abnormally high tides and coastal erosion.

“There has been coastal erosion with waves going right up to the sand dunes of the beaches,” Mr Campbell said.

The weather bureau is expecting sea flooding to inundate low-lying coastal areas on the mid-north coast and the Northern Rivers on Wednesday night.

“People who live in at-risk coastal areas should monitor their local sea level closely, stay well clear of the surf zone,” said NSW SES Commissioner Mr Murray Kear.

Essential Energy said extra maintenance workers were on standby up to the Queensland border after the windy conditions farther south toppled trees and power lines, cutting power to thousands of homes.

“We’ve got plenty of crews ready to go,” an Essential Energy spokeswoman told AAP.

An Ausgrid spokesman said some pockets in Sydney and the Central Coast were still waiting for power to be returned.

NSW Emergency Services Minister Mike Gallacher on Wednesday praised the SES for responding to flash flooding and fallen trees.

Torrential rain and winds topping 127km/h tore off roofs and downed powerlines, with more than 25,000 homes and businesses in Sydney and on the Central Coast blacked out on Tuesday night.

“People were well advised to batten down the hatches and prepare for the wind,” Mr Gallacher told AAP.

“There will no doubt be opportunities for councils to have a post-mortem on yesterday’s events and their preparedness for it.”
