There are multiple ways to prepare for the upcoming rainfall, following these steps may ensure the safety and well being of yourself, family and property.

Step One: What To Know

To have knowledge of hazards in your area download the Hazards Near Me app to your phone.

The app delivers specific information about what’s happening in your proximity and provides a three tiered warning system to portray the severity of the hazard.

You can also follow NSW SES on socials as well as Manly Unit SES and Warringah Pittwater SES for constant updates.

Step Two: How To Prepare

You can prepare for the forecasted rainfall ahead as well as potentially prevent major flooding to your home by following this advice from NSW SES.

Collect Sandbags:

Sandbags are a great way to divert water from coming into your home.

Northern Beaches Council and NSW SES have provided sand and sand bags in three locations around the Northern Beaches.

  • Denzil Joyce Oval carpark, located at North Curl Curl
  • Narrabeen Sure Life Saving Club
  • Balgowlah Golf Course, located on Sydney Road.

Note that you will need to bring your own shovel to scoop the sand.

Clean your gutters:

It is important to keep your gutters and downpipes clear as blockages can cause the water to overflow under the eaves into the roof cavity.

This can cause an array of issues leaky infrastructure to short circuited electricals.

Clearing the gutters along the street around your property will also prevent flood waters from diverting towards your home.

Be aware of where you park your vehicles:

With gusts of winds expected to hit 90 km/h over the weekend the SES recommend parking your vehicle away from any area where it may get crushed by a tree branch.

Avoid parking your vehicles in any area with a high risk of flooding – these areas can be viewed via the Hazards Near Me app on your phone.

Stay away from floodwaters:

Do not drive, walk or ride through floodwaters.

It is extremely dangerous, floodwater may be deeper and faster flowing than it appears and often contains hidden snags and debris.

Flash flooding also has the potential of turning a situation hazardous in an instant.

The water contains an array of diseases and bacteria and coming into contact with it may induce sickness.

Step Three: Who To Call

In an extreme weather event such as this emergency and rescue services are stretched thin and it is important to insure their resources are put to good use.

If there is a life threatening event do not hesitate to call 000 for emergency services.

If you need flood or storm assistance, call 132 500 for NSW State Emergency Services, they prepped to respond and support communities.
