Eleven men and one women fell from ladders on Thursday, many while clearing their gutters ahead of the deluge.

About 100mm of rain has been forecast for Melbourne between Friday and Sunday, while parts of Victoria are tipped to receive between 200mm and 300mm over the same period.

Nine of the 12 ladder victims were aged over 50, Ambulance Victoria says.
