FIRE authorities are hoping predicted rain tomorrow will dampen the threat from several big blazes burning across Victoria.

The Bureau of Meteorology have forecast up to 40mm of rain around the alpine area today which should bring relief to the large Harrietville fire.

The alpine fire has burnt 35,513ha and about 300 firefighters are working to build containment lines and back burning.

Swifts Creek Incident Control Centre spokeswoman said crews will continue back-burning if conditions allowed today along Blue Rag Track on the southern edge of Harrietville fire.

They were also dealing with two other fires, both which have been contained, the Dargo Mathesons fire, 15km north of Dargo, which started over a week ago and reached 1111ha in size.

And the Dargo Budwuid blaze, 2.5km south east of Dargo, which started yesterday and burnt 0.7ha.

"(The Dargo Budwuid fire) started yesterday morning, water bombers and ground crews wrapped it up pretty quickly . . . and it's likely to have advice removed today," the spokeswoman said.

She said they were hoping the predicted rain would help suppress the fire activity in the region.

"It's such a large steep area of Gippsland it's hard to wrap this fire up, so we are praying on rain."

Meanwhile near the Grampians in the west of the state Victoria Valley Complex incident controller Russell Manning said the Grampians fire is not spreading and is staying within containment lines.

"We're not saying it is controlled, it is effectively contained," he said.

"We're feeling pretty confident where the position of the fire is at the moment."

Losses from this fire, which started two weeks ago, includes 60 sheep, 128 kilometres of fencing, 65ha of hardwood forest, one hayshed, two machinery sheds and 30 tonnes of hay and silage.

No assets or livestock losses have occurred for more than a week but the fire has burned 1504ha of grazing land and 1036 ha of private bush and firefighters have built more than 200 kilometres of containment lines.

CFA fire crews were withdrawn from the fire ground earlier this week, leaving about 240 firefighters, mainly Parks Victoria and Department of Sustainability and Environment firefighters, plus crews from New Zealand and New South Wales, mopping up and patrolling containment lines.

Firefighters are being assisted by 11 aircraft and eight Hover Exit crews at Cassidys Gap.

Mr Manning said over the past two weeks DSE firefighters have battled more 30 fires in the Wimmera, including more than 20 in the Grampians National Park and the Little Desert.

"Plus CFA crews have responded to 50 fires on private property.

"Our firefighters and incident management teams have been really, really tested and have done a grand job."

Warnings have been downgraded to advice for the townships of Cherrypool, Glenisla, Mooralla, Woohlpooer, Bornes Hill and the Victoria Valley community.

Further east in Gippsland, the Aberfeldy fire has burnt 84,950ha and has been burning for 39 days and about 330 firefighters were still working on the blaze.

Crews are trying to secure control lines and complete burning around the Licola Valley to protect private property and firefighters were patrolling around Burgoyne’s Gap and Mt Useful for hot spots.
