Emergency Warning
The NSW SES is directing people in the following area(s) to EVACUATE BEFORE 11:30 pm Sat 17 Jan due to localised flooding:
- Narrabeen Lagoon and surrounds, including the BIG4 Sydney Lakeside Holiday Park.
You must evacuate before this time because floodwaters are rapidly rising and may impact properties.
You should evacuate to stay with family, friends, or alternate accommodation in areas unaffected by flooding.
If you remain in the area, you may become trapped without power, water, and other essential services. It may be too dangerous for NSW SES to rescue you, and buildings may not be able to withstand the impact of flood water.
What are we expecting?
A VERY DANGEROUS THUNDERSTORM producing heavy, locally intense rainfall that may lead to dangerous and life-threatening flash flooding was detected near Mona Vale and Manly.
Narrabeen Lagoon remains closed. The heavy rainfall may have resulted in flooding of low-lying areas and roads around the Lagoon.
This event may change quickly. NSW SES will monitor the situation and update warnings if the situation changes.
