A massive bushfire raging through several northern Perth suburbs overnight which forced residents to flee their homes remains out of control this morning, with unconfirmed reports of property losses amid ongoing extreme temperatures and high wind.

Firefighters faced dangerous and unpredictable conditions overnight as they battled the blaze that bore down on several suburbs including Wanneroo, Mariginiup and Banksia Grove. 

An emergency warning remains in place for parts of those suburbs, as well as Jandabup,  Tapping, Melaleuca, and Sinagra, with residents east of Pinjar Road in Tapping warned they are in immediate danger, as the fire danger escalates.

"Shelter in your home in a room away from the fire front and make sure you can easily escape," is the official advice.

Those to the west of Pinjar Road are instructed to leave now if it's safe.

More than 100 firefighters are battling the blaze that started yesterday in Mariginiup.

"I'm probably 700m from Pinjar Road which is where the fire was," he said.

"I'm not sure if we lost any houses in between, but we came under a fairly heavy ember attack around 10.30pm—10.45pm.

"There were a couple of people who kicked the doors in notifying people. Thankfully there was nobody home, So no injury, no loss of life or anything like that. Just property damage."

About 1,500 hectares of land is estimated to have been burned so far.

Extreme fire conditions are forecast for the area today, with the temperature expected to hit 40 degrees.

A heatwave warning has also been issued, as Perth faces its fourth consecutive day of temperatures above 35 degrees.

More than 1,000 properties in the bushfire area are without power, with at least 150 people spending the night at an evacuation centre set up at the Gumblossom Community Centre in Quinns Rock.

An animal evacuation centre has also been set up at Wanneroo Showgrounds.

'Red bullets' of fire

Tapping resident Alan Johns, who stayed back to protect his home and others, said embers fell like rain across the neighbourhood.

"It was not fun. The wind was spreading red bullets at you as you were trying to fight embers," he said.

"It was hitting the house it was hitting the roof."

He said the large trees in nearby bushland played a major role in spreading the fire.

"The big ones would get lit up and all of a sudden the embers would go however many feet… It was just ridiculous watching them go over your head," he said.

"The trees behind me, the biggest one, when they lit up it was just like the Statue of Liberty."

'Trifecta of terrible conditions'

Bureau of Meteorology forecaster Jess Lingard said a combination of factors made conditions difficult for crews overnight.

"The set up at the moment isn't great. It's hot, it's dry, it's windy. It's the trifecta of terrible conditions for fires," she said.

"The only saving grace that we've got is there's no wind change expected for today.

"We're going to be sitting in these north-easterly winds all day.

"They're going to be quite strong, at about 30 to 40 kilometres an hour, with some pretty decent gusts. But at least they'll always be moving in the same direction, which helps firefighters to plan."

Ms Lingard said a deepening trough across Perth and surrounding areas would likely mean conditions would remain the same for the next few days.

"We've got until early next week until we start to see anything significantly changing to winds," she said.

Cecilia Pham and her family were evacuated from the emergency warning zone overnight.

"I was in the house with the baby nursing her, and then I heard helicopters," she said.

"Oh my God water bombs, helicopters above us, I'm feeling like 'is that war?'"

Ms Pham said they initially drove to a shopping centre car park because they didn't know where to go.

They eventually found their way to the Gumblossom Community Centre evacuation centre 

"The sky was really red last night … we decided to go to the Wanneroo evacuation centre but it was so full and they closed, so we went up this way," Ms Pham said.

'We hoped for the best'

Tapping resident Denise Crooks said embers were raining down on on her street just before she fled her home yesterday.

"Frightening. It's a big fire, and it's throwing embers everywhere," she said.

"We just put all the sprinklers on, and hoped for the best.

"I'm hoping to drive home and still see our house in one piece."

The City of Wanneroo, where the fire is raging, is a mix of long established market gardens and modern suburbs that have been developed over the past two decades.

It includes densely populated subdivisions, schools and shopping centres, as well as agistments.
