Weather outlook includes increased chance of flooding and cyclones
Queenslanders are being urged to prepare now for severe weather events.
The Bureau of Meteorology’s (BoM) Severe Weather Outlook for October to April predicts a greater chance of flooding and cyclones for Queensland.
BoM climatologist Greg Browning said after a decline in the number of cyclones in Australia over recent decades this summer would likely see that trend ended.
"On average Australia sees nine to 11 tropical cyclones each year, with four crossing the coast,” Mr Browning said.
“With La Nina this year we are expecting to see slightly more tropical cyclones than average, and the first one may arrive earlier than normal.
“We know that cyclones can develop at any time throughout the tropical cyclone season, which runs from November to April.
“This means that communities right across northern Australia need to be prepared now and stay informed from the very start of the tropical cyclone season in October, right though until April."
The BoM said Queensland’s east coast had a 67% chance of more cyclones than the average of four. About a quarter of cyclones in the region cross the coast.
The current La Nina event is forecast to bring more rain to eastern and northern Australia, with some drought-affected areas already seeing rainfall deficiencies ease and water storage levels increase.
The bushfire potential is rated average for most parts of Australia this summer.
"This fire season we're expecting wetter than average conditions in eastern and northern Australia, so long-running large bushfires are less likely, however a wetter spring can lead to abundant grass growth, which could increase fire danger as it naturally dries during summer," Mr Browning said.
