The worst is yet to come for Melbourne and most of southern Victoria as authorities brace for damaging winds and flash flooding after a night of rain.
Gusts of up to 110 km/h are expected in Victoria's east on Sunday, while winds and heavy rain are expected to hit most of southern Victoria.
A run of warm days over the past week ended abruptly overnight as a deep, low-pressure system reached the state's southwest on Sunday morning.
The SES say they received 140 calls for help between Saturday night and Sunday morning, but that number is expected to grow.
"We're gearing up for another day of potentially strong winds," a spokesman told AAP on Sunday.
The low pressure system is forecast to move across Melbourne and the high country on Sunday afternoon
Rainfall of up to 60mm is likely in Melbourne while totals approaching 80mm may be recorded in the state's alpine region through Sunday night.
The Bureau of Meteorology say there is a possibility of flash flooding on Sunday night going into Monday in the state's east.
A severe weather warning is in place for Victoria's central and southwest, and the flood risk is expected to contract to the state's east, particularly in East Gippsland.
Geelong, Ballarat, Kyneton, Kilmore and Falls Creek and Bacchus Marsh may also be affected by heavy rainfall and damaging winds.
As always, the SES is warning people to secure loose items and to stay out of floodwaters.
