“It’s not often you see destructive winds, and the winds with this one are more widespread and longer lasting than previous fronts.”
Despite the extreme conditions, it was business as usual at Melbourne Airport on Friday morning, with flights running as scheduled.
The full force of the system is expected to rattle the state from 10am until 3pm on Friday.
By 10.30am on Friday, the State Emergency Service had received 93 calls for assistance in 24 hours, and was expecting many more.
Fallen trees accounted for 66 of the calls while the other 23 were for damage to buildings.
The SES urged people to take safety precautions, including moving cars from under trees, securing loose personal items and keeping clear of fallen power lines.
The winds are also expected to whip up dust storms across the state, particularly in the afternoon.
But once the wind has eased, get ready for rain.
Showers are expected to begin on Friday night, with five to 15 millimetres expected to fall across the metropolitan area.
The rain will stick around on Saturday, with the heaviest falls in the morning before a chance of thunderstorms and hail in the afternoon.
The downpour is then expected to ease to possible showers on Sunday.
The weekend will also bring a dip in temperatures to 13 degrees after a mild 19 degrees on Friday.
The new bout of severe conditions comes after the Bureau’s Melbourne Airport weather station recorded its windiest July in 20 years.
“It has been notable. We’ve had a really dry winter so far and we’ve had very much below average rainfall and above average winds,” senior forecaster Michael Efron said.
The average Melbourne rainfall for July is around 45 millimetres, but last month’s total only reached 19.4 millimetres.
