Stay safe in summer storms: tips from the NSW State Emergency Service

We’re expecting a wetter-than-normal summer in Sydney this year. Here’s what you can do now to protect yourself, your home and neighbours during summer storms .

You might have heard that there’s a La Niña weather pattern headed our way, with the worst set to hit between now and March 2021. That means we’re about to have higher than average rainfall this spring and summer, and we may see torrential rain and flash flooding.

We spoke to NSW State Emergency Service City of Sydney Unit Commander Robert Cooper to find out what steps you can take now to reduce the chance of storm damage in your home.

“There’s not much you can do once a storm hits,” said Robert. “Our message is to control the things you can control now and know your plan for when a storm arrives.”

Avoid flood waters at all costs

More rain means more chance of flooding. Flash floods are fast moving and extremely dangerous. They can happen at any time, but usually take place a few minutes to a few hours after intense rainfall when creeks, waterways and stormwater drains struggle with the extra influx of water.

Our new 2km stormwater drain in Green Square should reduce some effects of flash flooding. But the risk of floods in our local area is still high.

You should never drive, walk or ride through flood waters. In fact, if you remember one thing, it’s this:

“If it’s flooded, forget it. Find another way.” - NSW SES Unit Commander Robert Cooper

You might be tempted to take a chance and drive through shallow flood waters. Think again. In a 2016 test, engineers from the UNSW Australia found that a small car like a Toyota Yaris, weighing 1.05 tonnes was moved by water only 15cm deep and with a flow speed of as little as 3.6 kilometers an hour.

Take care around trees

Every year the State Emergency Service responds to about 300 jobs in our local area. Most of these are for trees that have come down in storms.

Take these steps to improve safety around nearby trees :

  • Check trees around your home. Overhanging branches may pose a safety risk in a storm. You’ll need a permit to prune or remove trees on your property.
  • If there’s a tree in your neighbourhood you think needs pruning or removal, you can report an issue to us online.

If a storm is on the way:

  • Avoid parking your car under a tree if you can.
  • Don’t take shelter under trees.

Prepare your home for hail and heavy rain

Hail often accompanies summer storms.

Take these steps to reduce the chance of hail damage in your home:

  • Clear your gutters. When hail melts, gutters can get overloaded quickly.
  • If you have a skylight, check the seal is in good condition.
  • Take a look at the state of your roof tiles. Fix any cracked or broken tiles.

Create a personal emergency plan

If you know what to do, you’re more likely to make the right choices. Create a personal emergency plan for your family and close friends. This should cover what to do, where to meet, where to go and how to communicate in an emergency.

The Red Cross Get Prepared app can help you create, record and put your plan into action.
