The Bureau of Meteorology says heavy winds averaging 50-60km/h with peak gusts of 90-100 km/h are expected to develop across Victoria early Wednesday morning.

The bureau released the severe weather warning on Tuesday.

A deep low pressure system currently over South Australia has been predicted to move southeastwards and is expected near Adelaide overnight before moving nearer to the western Bass Strait on Wednesday, the statement read.

Ballarat and Maryborough have been listed as locations which may be affected by damaging winds on Wednesday.

Bureau of Meteorology senior forecaster Stephen King said winds are expected to pick up overnight and into the morning, but are set to ease as the day progresses. 

The State Emergency Service is urging local residents to move vehicles under cover or away from trees; secure or put away loose items around your house, yard and balcony and keep clear of fallen power lines. 

Temperatures are set to peak at 29 degrees on Wednesday, continuing the humid weather experienced across the region on Tuesday.

Explaining the tropical-like weather, Mr King said a tropical air mass over the state has caused a steamy feeling similar to that experienced in far north Queensland.

“It will be with us until Friday when it will be flushed out to the east, bringing dryer weather,” he told The Courier on Tuesday afternoon.

At this stage there is a chance of a thunderstorm on Wednesday evening.

With tropical weather and storms set to rock the state over the coming days, Victorians are also being urged to prepare and plan holidays and trips accordingly.

Emergency Management Commissioner Craig Lapsley said there were some simple steps people can take to ensure they and their loved ones stay safe during the holiday period.

“Victorians and visitors need to stay alert and aware of the risks, with the winds on Wednesday increasing the fire danger particularly for the north, west and central parts of the state, followed by storms and flash flooding moving through the next day,” he said.

“Don’t camp under trees, extinguish your campfires properly, stay on higher ground and take care while driving on the roads.

“If you are at home make sure you secure loose items, and you are prepared for any potential power outages.”
