Tropical Cyclone Seasonal Outlook for northwest Australia

Issued at 8:23 am WST on Monday 9 October 2017.

Tropical Cyclone season fast approaching - time to prepare.

The Bureau of Meteorology today issued its Tropical Cyclone Seasonal Outlook for 2017-18.

Acting State Manager for Western Australia Mr Grahame Reader said that with the start of the season on 1 November fast approaching, now is the time for residents to begin preparations and remain vigilant throughout the season.

"Although the number of tropical cyclones off northwest WA last season was about average, with two tropical cyclones impacting the WA coast, there were also numerous tropical lows which produced widespread flooding and squally winds across northern WA," he said.

"Weather hazards associated with cyclones can include storm surge flooding, destructive winds, inland flooding from heavy rainfall and high seas and swells. Tropical lows can also produce heavy rainfall, inland flooding and squally winds."

Mr Reader said that climate models are indicating an average number of tropical cyclones this season, but he cautioned that the number of tropical cyclones is not a good indicator of the threat to communities.

"If just one cyclone or tropical low significantly impacts a community, then that will be a bad season for people living there". Tropical cyclone season runs from 1 November to 30 April.

Fire and Emergency Services Commissioner Darren Klemm said the tragic loss of lives last wet season should not be forgotten.

"People often underestimate the life-changing impact a cyclone or flood can have. Complacency can lead to destruction that is not only distressing and expensive, it can sadly be deadly," Commissioner Klemm said.

Communities in the State's north remain at serious risk of the devastation of cyclones and need to prepare now to keep their homes and loved ones safe. Keeping safe is as simple as securing outdoor items like boats or trailers, preparing an emergency kit and taking heed of the community warnings.

Summary of the Tropical Cyclone Seasonal Outlook for Western Australia:

* ~55% chance of an above average number of tropical cyclones in waters off the northwest coast (average number is five).

* Likelihood of around two coastal impacts.

* Significant risk of at least one severe tropical cyclone coastal impact during the season.
