Peak wind gusts reached 96km/h in Hamilton on Wednesday, 96km/h in Portland on Thursday and 78km/h in Warrambool on Friday.

The Bureau of Meteorology issued another severe weather warning for damaging winds at 11am on Saturday.

The warning said although winds were expected to ease during Saturday afternoon, damaging winds were expected to redevelop over parts of southern Victoria during Sunday, mainly over coastal and alpine areas.

South-west State Emergency Services received more than 100 calls for assistance overnight on Wednesday.

Hamilton district unit controller Bruce Farquharson said members had cleared another two trees from the road on Saturday morning.

He said the first call was about 6.30am to a tree over the Glenelg Highway, west of Hamilton.

"The second was about half-an-hour later where another tree had fallen over part of the road at the Wannon Falls Reserve," he said.

"The traffic could get past the tree but if they ran into it, it would be a problem. That's one of the biggest issues with trees, if people run over them unexpectedly they can cause a lot of damage. That's why motorists should really drive carefully so that they can stop safely if and when they need to."

A cold front has dumped 50 millimetres of rain on Portland since Monday, 46.2 mm on Warrnambool, Casterton 37 mm and Mortlake 26.4 mm.

Mr Farquharson said the heavy rainfall had saturated the soil, meaning more trees were likely to fall down.

"When it's dry we don't see as many trees coming down but when the soil is wet and saturated and you get those high winds, we got more trees falling onto the roads," he said.

"After Wednesday the Southern Grampians Shire had hundreds of trees across the northern part of the shire that they had to clear and some roads were closed for quite some time.

"This week is probably the busiest we've been in over a year. And it wasn't just the SES, we had council out there, Regional Roads Victoria on the highway and a lot of farmers with their tractors giving us a hand."

Warrnambool SES unit controller Giorgio Palmeri said members worked with police to remove a fallen tree that was blocking the north bound lane of Wangoom's Hugh Road at 5am on Friday.

"Police were already on the scene and we worked with them for 20 minutes to make the area safe and clear," he said.

During damaging winds and high rainfall, SES advises that people should move vehicles under cover or away from trees, secure or put away loose items around the house and keep clear of fallen power line.

Storm and flood emergencies can be reported by calling 132 500.
