The Bureau of Meteorology (BOM) has issued a severe weather warning for damaging winds and surf.
Just after 11.00am today (Tuesday, 24 August) the BOM issued a revised severe weather warning. A strong cold front has moved across the coast and will stall, which is likely to cause damaging winds and surf.
As the cold front stalls offshore, a low pressure system will form off central coastal waters, generating large waves and moving slowly east during the mid-week.
“From Tuesday afternoon, significant wave heights could reach in excess of 5m for much of the southern and central NSW coast including Sydney with large seas possibly generating significant coastal erosion,” said BOM Meteorologist Miriam Bradbury.
In preparation for the potentially severe weather event, Northern Beaches Council have inspected and prepared lagoon entrances for mechanical opening at Narrabeen, Dee Why, Curl Curl and Manly. They have also inspected stormwater systems to ensure they are free-flowing.
NSW SES has warned people to move vehicles undercover, away from trees and powerlines that may fall, and secure outdoor items that may blow around and cause damage in gusty winds including furniture, BBQs, gas cylinders, cushions, plants, play equipment and trampolines. They have also reminded people not to drive, walk or ride through floodwaters.
NSW Surf Life Saving (SLSNSW) has urged people to stay out of the water with hazardous conditions likely for coastal activities such as rock fishing, boating, surfing and swimming.
SLSNSW Director of Lifesaving Joel Wiseman warned people to exercise caution because emergency responses might be delayed.
“With the current COVID environment our resources aren’t committed to actively patrolling until mid-September, so if you take a risk and find yourself in trouble there could be a delay in response in getting emergency services to the scene. People are strongly urged to check BeachSafe and understand your limitations if you do decide to take a risk,” said Mr Wiseman.
Marine Rescue NSW have asked people to stay off the water and stay at home during the storm, “For much of NSW it’s going to be a wet, windy and wild day out on the water – definitely the sort of day to stay at home.”
High winds may cause branches to fall across power lines. Around 11.15am today, firefighters from Mona Vale Station responded to a call for wires down at Minkara Road, Bayview. Ausgrid warn people to stay at least 8m (two car lengths) away from fallen power lines and contact them on 13 13 88. Power outages can be checked via the Ausgrid website.
For emergency assistance during floods and storms, call NSW SES on 132 500. In a life threatening emergency, call Triple Zero (000).
