On Saturday, the roof of a Trentham east home

was blown away.

The roof of Gisborne Secondary College science block was lifted.

SES volunteers attended more than 25 jobs last Wednesday and Thursday when the strong winds swept through the region.

And a Bureau of Meteorology forecaster has warned the wet conditions are expected to continue this week.

A number of large trees fell across driveways from Lancefield to Lauriston last week.

Tree branches fell onto power lines and roads, throwing traffic into chaos.

SES' Woodend unit controller Dean Gladman said strong winds and heavy rains had damaged trees across the Macedon Ranges.

Trees had fallen down on both roads leading out of Woodend, along Black Forest Drive and on the Woodend-Romsey Road.

"The majority of our jobs were in Woodend, but we had a number in Kyneton [too]," he said.

"Trees were coming down blocking roads, access to properties and damaging buildings. We had one job involving a shed which was blown onto a neighbouring property."

Mr Gladman said it took four SES members about an hour to clear a path for a Woodend family.

"We had an extremely large tree split in three directions, which had blocked a driveway and the family couldn't leave their property.

"We managed to clear a path; it took us about an hour."

The walkway at the Five Mile Creek bridge, also at Woodend, was flooded.

Western Water's Gisborne reservoir is at 4.7per cent capacity, up slightly on last year.
