Two bushfires are threatening lives and homes around Albany and other communities across Western Australia's south coast, as winds from the season's first strong cold front fan flames, sparking spot fires up to 1.5 kilometres ahead of one blaze.

One of those fires is burning 10 kilometres west of the city of Albany in the Redmond area and the other is in the Napier area near the Porongurup National Park, about 20km to Albany's north east.

More than 30 fires remain active in the region, and DFES said it was "an unprecedented fire situation within the City of Albany".

At least two homes have been lost in the town of Wellstead, east of Albany, according to Albany Mayor Dennis Wellington.

"One house confirmed as being burnt out, there's another shed which is full of farm materials burnt out," Mr Wellington said.

He said livestock had been lost, and it was fortunate nobody had been injured in the fires.

An emergency warning for a fire in Redmond has now been extended to the Elleker township, about 16km west of Albany, and people in the area around the Lake Powell Nature Reserve.

Those in the area have been warned they are in danger and need to act immediately to survive.

Mr Wellington said about 4,000 hectares had been burnt in this area so far, and about 17,000 hectares in the Porongurup fire.

"It's just something we've never experienced before," Mr Wellington said.

It was earlier reported that Nutkin Lodge farmstay in Peaceful Bay had been destroyed, but owner Linda Hoskin told ABC Radio the property had been saved and all guests were safe after earlier being evacuated.

Three other fires have been downgraded to watch and act level, including a fire at Albany's Goode Beach.

Authorities said people in the vicinity of this fire need to stay alert to changing conditions and there is a possible threat to lives and properties.

Wind gusts of more than 100 kilometres per hour have been recorded at Albany and the Bureau of Meteorology is warning winds will intensify during the day with gusts of up to 125kph forecast.

More details on all fires can be found on the Emergency WA website.

Two fires threaten to combine

Department of Fire and Emergency Services (DFES) Superintendent Wayne Green said one of the biggest concerns was the fire burning in Napier, about 30km north-east of the city of Albany, which is home to about 35,000 people.

An emergency warning has been issued for the Napier fire, which is threatening to join up with another fire burning in the south-east of the Stirling Ranges, a rugged and mountainous national park north of the township.

Mr Wellington said one of the worst scenarios would be if the two fire fronts at Napier and the Stirling Range, both north-east of Albany, were to combine.

"What we don't want to see is the Stirling range one and the Napier one meet up, because that just gives a huge fire front to fight," he said.

Superintendent Green said there were dozens of fires across the area and crews were under a lot of strain.

"All of our resources are absolutely stretched to the point where some of the fires that are coming in and being reported now aren't even getting a response," he said.

"Because our resources are so tied up with making sure that people are being evacuated safely."

The southern half of the state is also being battered by the first strong cold front of the season, but while strong winds are whipping up flames, there is not enough rainfall to have a major impact on most of the fires.

"We can't rely on any of this rain that's starting to drizzle through at the moment, it seems to be having not that much affect out on the fire grounds," Superintendent Green said.

The fires have spread quickly, and Superintendent Green said one fire front was almost the length of the Stirling Ranges.

He said crews were managing to stay on top of the blazes in the Napier and Redmond areas, but DFES was not anticipating any let up.

"All I'm doing is urging our residents and our community to monitor Emergency WA, have a look at the location of the fires and enact your plans now.

"Don't wait for any further advices — have a look at right now, if it's something near your property put your plan into play right now."

'It's just absolute mayhem'

Mr Wellington said he had never seen a fire on this scale.

"I've never seen anything like it … it's just absolute mayhem," he said.

"They're serious fires, there's a lot of fuel in front of them — and they're in areas which are very difficult to control.

"The fortunate part is that we've got some new crews on the ground."

Mr Wellington said crews had travelled from the nearby regional hubs of Katanning, Cranbrook and Tambellup to assist worn out volunteer firefighters.

School under threat

South Coast regional manager Greg Mair from the Department of Parks and Wildlife said the fire has burnt through large swathes of the Stirling Range National Park.

"The fire took a big run overnight, it's come out of the national park under those strong northerly winds and it has burnt through private property around the Two Mile Lake area … and burnt down towards South Stirling nature reserve and South Stirling Primary School," Mr Mair said.

He said the school had not been directly impacted by the fires but the full picture was yet to emerge.

The Department of Education cancelled classes at the South Stirling Primary School on Friday as a precaution.

"Because the main run has been in hours of darkness, the actual edge of the fire is a little unclear," he said.

"We've got a general impression of where it's come but once we get a little daylight we can put an aircraft up and get a main plot on it, that will help us identify the main threat areas."

Mr Mair said the fire has torn through about 16,000 hectares, with homes and private property damage unconfirmed at this stage.

"Most of that is in the national park but it includes an undetermined amount of private property, so we haven't separated those figures out yet. [It's] a very large fire," he said.

Little relief from cold front

The Bureau of Meteorology Senior Forecaster Matt Boterhoven said a cold front sweeping over the state had brought little relief.

"We've had a strong cold front move over the south-west of the state, challenging fire conditions near Albany," he said.

"They recorded [wind] gusts up to 102kph just before 2am.

"Since then it's cooled off a little, there's some humidity, there are some showers but only light rainfall recorded so far."

Mr Boterhoven said light rainfall is expected tomorrow and heading into the weekend, but that gusty winds are also forecast.

A south-westerly change was expected to bring more significant rainfall later today, but it would also bring stronger winds that could fan the flames.

"Activities should increase Friday evening and Saturday morning with up to 10 millimetres [of rain]," he said.

Warning for residents to take shelter

An emergency warning — the highest threat level — is in place for Redmond, Marbelup, and Elleker including the Elleker townsite on the western side of Albany.

A bushfire watch and act notice has been issues for people south of the Elleker townsite and between Wilgie Road to the west and Prescottvale Road to the east, down to the coast in Redmond, Marbelup and Elleker.

A second emergency warning was issued this morning for parts of Napier in the City of Albany. The alert has been issued for people in an area bounded by Chester Pass Road, Takalarup Road, Deep Creek Road, Penn Road and Mindijup Road.

A bushfire watch and act notice has also been issued for people in an area bounded by Takalarup Road, Palmdale Road and Moir Road including Takalarup and Manypeaks in Napier.

The bushfire is moving fast and in a southerly direction and homes are under threat now, according to DFES.

Emergency warnings have also been issued for an area south-east of Stirling Range National Park in the city of Albany.

Authorities say people in the vicinity of these fires are in danger and need to act immediately to survive.

For these people, DFES advises:

It is too late to leave, leaving now would be deadly.

If your home catches on fire and the conditions inside become unbearable, you need to get out and go to an area that has already been burnt. Close all doors and windows and turn off evaporative air conditioners, but keep water running through the system if possible.

A watch and act is in place for Goode Beach and Frenchman Bay across the inlet from the town.

Albany Mayor Mr Wellington warned residents to exercise extreme caution in the area.

"You just got to be careful if you are on the roads, there could be trees down and still coming down," he said.

"We can always replace the houses and that sort of thing but you can't replace lives."

The Stirling Ranges fire is the result of an escaped burn, a DFES statement said.

City of Albany community emergency services manager Brendan Gordon said strong southerly winds had picked up during the evening and were pushing the fires quickly towards farming properties.

"Both of these fires will impact properties really quickly," he said.

"We're chucking everything at these fires and hoping for the best."

Rain brings relief to Peaceful Bay

An earlier emergency warning for the holiday-home community of Peaceful Bay in the shire of Denmark has been downgraded to a watch and act as rainfall dampened flames.

However, homes along Ficifolia Road and Peaceful Bay Road including the coastal Peaceful Bay township, comprising around 300 homes, may still come under threat.

The Department of Fire and Emergency Services said the bushfire is fast-moving, out of control and unpredictable.

Roads in the area have been closed.

DFES said those planning on staying to defend their homes must not rely on mains water pressure. Those with access to a water tank should start patrolling with their hose and put out spot fires.

Motorists are asked to avoid areas affected by the fires, reduce speed and drive carefully due to smoke.
