Storm season begins: Australians are warned to prepare for a summer of wild weather starting TODAY - here's how hard your area will be hit

Australians have been warned to prepare for another summer of dangerous weather bringing storms, flooding and bushfires - with wild conditions from this week.

Cairns and central Western Australia near Port Hedland received morning showers as storms brew over Queensland's east coast on Monday.

Sydney, Melbourne and Brisbane are forecast for sunny days of 24C, 25C and 28C respectively, but experts have said the Sunshine State is in line for potentially devastating weather conditions in the coming months.

The Bureau of Meteorology has warned of more cyclones in northern parts of the state after a La Niña cycle was declared last month.

A La Niña occurs when stronger equatorial winds, blowing east to west, cool the Pacific Ocean in the tropical north of Australia.

Victoria on Monday is expecting late showers in its south-west and mostly sunny weather elsewhere in the state.

Canberra and Sydney will be mostly sunny, although showers and the odd storm are expected in the north-east of New South Wales.

Tasmania is forecast for late showers in Hobart, while Adelaide in South Australia will be mostly sunny.

Western Australia and the Northern Territory are both expected to be sunny on Monday - with Perth emerging from last week's mild weather to highs of 28C. 

Brisbane's State Emergency Service regional manager Mark Dole said the main risks brought by the summer months were storms and flooding and residents needed to start thinking of evacuation plans.

'How would you maintain living at home for a period of time if you were cut off? Where would you go if you needed to evacuate?' he told ABC News.

'It's one thing to develop a plan but the most important part is to actually practise it with the people who will be involved in it.'

The Rural Fire Service's regional manager for Brisbane Tim Chittenden meanwhile warned the bushfire threat was just as potent as last year.

'The really important part of that is to sit down with everyone that lives at that home to make sure that they all understand the plan and they all understand what to do,' he said.

Last week, The Bureau of Meteorology issued severe weather warnings for Victoria, South Australia and Tasmania following the formation of a La Nina event and a massive low pressure system spanning much of the country.

BOM has officially declared the first La Niña event since 2010 to 2012, when floods ravaged Queensland, killing 33 people. 

This brings more rainfall during summer and reduces the risk of a summer bushfire. 

The risk of flooding and cyclones, however, is heightened.  

La Niña events often form in autumn or winter, before dissipating in late summer. 

The greatest effect normally occurs during the spring and early summer period.

They usually last for about a year but can sometimes be shorter or longer.

During the last La Niña between 2010 and 2012, the weather bureau said Australia had one of the 'wettest two-year periods on record'.
