WHAT TO DO:

DFES advises:

  • Get ready for dangerous weather by preparing your home inside and out.
  • Secure boats, caravans, trailers, garden sheds, outdoor furniture, rainwater tanks, LPG bottles, loose material and rubbish around your home and workplace.
  • Ensure your emergency kit and relocation kit are complete and check your family knows what to do.
  • Check in with friends and neighbours to make sure they’re preparing too.
  • Holidaymakers and people travelling through the area should speak with their accommodation provider about their cyclone plan and decide what you will do if the cyclone will impact the area.
  • North West Coastal Highway will possibly be closed from Friday and travellers north of Minilya will not be able to travel south. 
  • Your only option then will be to travel further north, and there could be further restrictions on major highways in the coming days.
  • If you are on a vessel on the water or on an island off the coast between Onslow and Jurien Bay, including the Abrolhos Islands, prepare to move to a safer area.


CYCLONE DETAILS:
As at 9 April 2021 08:53 AM the Bureau of Meterology advised:

Tropical Cyclone Seroja expected to bring dangerous weather conditions to the west coast during Sunday or Monday.

Intensity: Category 1, sustained winds near the centre of 75 kilometres per hour with wind gusts to 100 kilometres per hour.
Location: within 45 kilometres of 19.0 degrees South 110.0 degrees East, estimated to be 540 kilometres northwest of Exmouth and 760 kilometres north northwest of Carnarvon.
Movement: southwest at 18 kilometres per hour.

Tropical Cyclone Seroja is forecast to gradually intensify as it tracks to the southwest over open waters today and then to the south on Saturday. On Sunday, Seroja is expected to turn to the southeast and accelerate towards the west coast before making landfall late Sunday or early Monday between Carnarvon and Jurien Bay.

Hazards:
Gales with gusts in excess of 90 kilometres per hour are likely to develop in an area between Coral Bay and Lancelin during Sunday afternoon and evening.
Gales will extend inland into the Wheatbelt and southern Goldfields during Monday.

Destructive winds with gusts in excess of 125 kilometres per hour are forecast to occur closer to the centre of Seroja as it moves across the coast and into the Wheatbelt.

Heavy to intense rainfall and flash flooding are likely close to the track of Seroja during Sunday and Monday.

Abnormally high tides could cause minor flooding at the coast between Coral Bay and Lancelin, increasing to be serious flooding in the Denham and Shark Bay region.

COVID-19:
What to do if you are self-isolating or quarantining due to COVID-19:

  • If you are in an area subject to COVID-19 restrictions, put your cyclone plan into action now and continue to follow precautions to minimise spread of the virus.

 

If you have been personally directed to self-isolate or quarantine due to COVID-19:

  • Decide where you will shelter during the cyclone. If it is not safe to shelter in your current location, find alternative suitable premises and wear a mask.
  • If a Red Alert has been issued for your location, shelter in place immediately.
  • If you are unable to return to your quarantine location within one hour, telephone WA Police on 131 444 to advise them you have had to leave due to an emergency.
  • Regardless of your location, continue to follow COVID-19 precautions and maintain appropriate physical distancing.

ROAD CLOSURES AND CONDITIONS:
Some roads may be closed and motorists are asked to reduce speed and drive carefully.

The forecast path shown above is the Bureau's best estimate of the cyclone's future movement and intensity. There is always some uncertainty associated with tropical cyclone forecasting and the grey zone indicates the range of likely tracks of the cyclone centre.

Due to the uncertainty in the future movement, the indicated winds will almost certainly extend to regions outside the rings on this map. The extent of the warning and watch zones reflects this.

This product is designed for land-based communities; mariners should read the coastal waters and high seas warnings.
