NSW Storm Emergency: Evacuations Ordered as Deadly Winds and Flash Flooding Persist

NSW is in the grip of a fast-moving storm emergency, with evacuation directions issued in parts of Sydney’s Northern Beaches as destructive winds and intense downpours trigger flash flooding, dangerous surf and widespread disruption. Authorities are urging residents to take warnings seriously, avoid unnecessary travel, and prepare for conditions to remain volatile as the system tracks north along the coast.

Across the state, emergency crews have been responding to a surge in calls for help as trees come down, roads flood and power outages hit pockets of the coast and ranges. The NSW State Emergency Service (SES) has warned that even short bursts of heavy rain can overwhelm drains and creeks, quickly cutting off streets and trapping vehicles. If you need emergency help in a flood or storm, the SES says to call 132 500 (and 000 in life-threatening situations). You can find official updates and safety advice on the NSW SES website.

Evacuation directions issued for Narrabeen Lagoon area

One of the most urgent warnings overnight has been centred on Sydney’s Northern Beaches, where authorities issued a direction for people in and around Narrabeen Lagoon (including the BIG4 Sydney Lakeside Holiday Park) to evacuate before a set time due to rapidly rising water and the risk of properties being impacted. These evacuation directions are typically issued when flash flooding or localised creek and lagoon flooding is expected to worsen quickly.

If you’re in an affected area, follow the instructions in the latest official alert and leave early if directed. If roads are already flooded, do not attempt to drive through—water depth can be deceptive, and vehicles can be swept away in seconds. Keep your phone charged, pack essential medication, documents and supplies, and let family or friends know where you’re going.

“Very dangerous thunderstorms” and life-threatening flash flooding risk

Weather warnings overnight have highlighted the risk from very dangerous thunderstorms capable of producing heavy, locally intense rainfall. In one alert, the Bureau of Meteorology warning text (republished via ABC Emergency) noted storms detected near Mona Vale and Manly and tracking inland toward parts of Sydney, with the potential for dangerous and life-threatening flash flooding. You can monitor live warning text via ABC Emergency, which republishes official warning information and maps.

Flash flooding is especially hazardous because it can develop with little notice—sometimes in under an hour—turning local streets into flowing channels. The SES and emergency agencies repeatedly stress three key rules: don’t drive into floodwater, don’t walk through floodwater, and move to higher ground early if water begins entering low-lying areas.

A tragic death as winds lash the NSW coast

As the storm front moved through the Illawarra and south coast, a woman died after a tree fell onto her car near Macquarie Pass during the severe conditions, underscoring the danger from falling trees and branches during damaging wind events. Authorities are urging people to stay away from forested roads and avoid parking under large trees when winds intensify.

If you’re at home, secure loose outdoor items (bins, furniture, trampolines), keep away from windows during peak gusts, and move vehicles to safer areas if possible. If a tree or powerline comes down, treat it as live and keep well clear.

Hundreds of call-outs as flooding and wind damage spreads

SES crews have carried out rescues and responded to hundreds of requests for assistance across NSW as the storm has moved along the coastline. Reports across multiple regions include vehicles stranded in floodwater, fallen trees blocking roads, and localized inundation in low-lying suburbs. In bursts of intense rainfall, even normally safe routes can become impassable—particularly near creeks, lagoons, and underpasses.

If you must travel, check road conditions before leaving, avoid coastal routes exposed to surf or debris, and plan a safer inland alternative. If you’re already on the road and water is rising, turn around early. The safest decision is the one you make before you’re forced into a dangerous situation.

Beach closures and hazardous surf: “Don’t take chances”

Along the Sydney coastline and parts of the Central Coast, dangerous surf and rough seas have triggered beach closures as the storm generates powerful waves and hazardous conditions. Even experienced swimmers and rock fishers are being urged to stay out of the water. A quick check of beach status and safety conditions can be made via BeachSafe, which provides beach information and safety guidance across Australia.

During storm events, surf conditions can change rapidly and rip currents strengthen. The safest choice is to treat closures as non-negotiable and avoid coastal rock platforms, sea walls and exposed headlands where waves can sweep across unexpectedly.

What to do right now- SES-style checklist

• Follow evacuation directions immediately if you’re in a warned area (leave early, take essentials).
• Stay indoors during peak storm activity; avoid balconies and windows in strong winds.
• Do not drive into floodwater; turn around and find a safer route.
• Charge devices and keep power banks ready in case of outages.
• Move to higher ground if water begins entering your property or rising near access roads.
• Keep updated via NSW SES and official warning channels; conditions can shift quickly overnight.
