A low pressure system is expected to batter southern states with storms and strong winds.

"Tomorrow is going to be amongst the windiest days, if not the windiest day of the springtime," meteorologist Angus Hines said.

Strong winds are expected to intensify overnight and move into eastern parts of Victoria and NSW tomorrow.

Severe weather warnings are in place across SA, Victoria and NSW, with wind gusts reaching 90 to 110 km/h expected in some areas overnight.

Residents in the south-east of South Australia, most of Victoria and parts of south-east and eastern NSW, including the Blue Mountains and the Illawarra, are warned to brace for the brunt of the fierce conditions.

Strong winds and storms forecast for Victoria tomorrow could topple entire trees.

"It will be Wednesday morning where the winds are strongest in south-west Victoria," Hines said.

"That is where we will see the potential for those gusts over 120 km/h, which is rare to see winds of that speed."

Coastal areas between Cape Otway in Victoria and Robe in South Australia are expected to receive destructive wind gusts up to 120 km/h to 130 km/h tomorrow morning.

Emergency services are warning residents to brace for damage to property, cars and power lines as destructive winds threaten to topple trees and branches.

Severe storms and heavy rain are also forecast for northern parts of Tasmania with rainfall totals up to 50 mm in parts of the state.

Conditions across the south-east part of the country are expected to stablise tomorrow evening as the system moves offshore.
