The welcome burst of springtime sun has brought with it gale-force winds to five Australian states and territories, triggering mass power outages for thousands.

A severe weather warning for damaging wind gusts is in place for residents in Victoria, South Australia, Tasmania, the ACT and southern parts of NSW.

Wind gusts reaching up to 90km/h have ripped off a roof from a home in north-east Melbourne, while the airport has recorded the strongest winds of more than 100km/h.

The wind also brought down what appeared to be a corrugated roof on a road in Fawkner, north Melbourne.

The SES said it is responding to more than 500 incidents across the city.

Train lines are also impacted as the ferocious winds damaged cabling and ripped up power lines.

Thousands of residents in Melbourne and greater Victoria are without power this afternoon after a surge in wind gusts.

Extreme weather conditions have caused unexpected power outages for more than 3000 people across the city.

Power outages also impacted thousands of people in Tasmania earlier today after wind gusts topping 102km/h were recorded in Hobart.

Despite the windy conditions, it will remain a sunny one for the rest of today.

Warmer weather for most of the country
