Gale-force winds of up to 80 kilometres per hour are expected to hit Melbourne today, beginning this afternoon and extending into the evening, says Stuart Coombs of the Bureau of Meteorology (BOM). Wind gusts of up to 100 kilometres per hour are expected across Port Phillip Bay.
BOM expects Melbourne to receive another 10 to 20 millimetres of rain today, with the biggest rainfall to come in the afternoon.
Emergency services and Vic Roads are warning drivers to go slow in light of the rain and wind, and not to walk, ride or drive through flood water.
The State Emergency Service has also advised people to move cars under cover or away from trees; to secure or put away loose items around houses, yards and balconies; and to keep clear of fallen power lines, creeks and storm drains.
While overnight Melbourne saw roughly 19 millimetres of rain – beating out April's total rainfall – it didn’t come close to the average rainfall for May, which is roughly 57 to 58 millimetres, says Coombs. Some of Melbourne's outer suburbs experienced heavier rain, with Dandenong receiving 31 millimetres.
The weather has caused power outages in the Apollo Bay area, the Herald Sun reports. Commuters also told the newspaper that parts of the CBD around Queen and Collins streets were “like a river” this morning.
There was flooding on Montague Street beneath the Westgate Freeway, in Templestowe and in Frankston.
Earlier this week Melbourne recorded one of its coldest May days in decades, with a maximum on May 9 of 12.8 degrees. The last time this happened was May 6 in 1970, when the top was 11.7.
