Huge wildfires in Canada force thousands to evacuate

Huge wildfires are threatening towns in Canada and forcing thousands to evacuate.

About 120 fires are raging across the country and dozens of them are "out of control".

Canadians are no strangers to wildfires and once again they're forcing people from their homes.

Officials are warning of what they call an "explosive fire season" this year, with one blaze already around 20,000 hectares in size.

"Anything to do with the fire I get upset, because I don't know if I'm going to survive it or not. I lost everything in 2016 and I had to start over," said one woman caught up in the evacuations.

In the province of Alberta in Canada's west, the small city of Fort McMurray is in serious danger.

More than 6000 people have been evacuated as the fire burns just 8km from the city's edge.

"Everything was covered in burnt embers and whatnot, so it was time to get out,"  one local man said.

At one point this week, the fire became so overwhelming it could only be fought from the air.

"The skies are covered in smoke. Firefighters have been pulled from the frontline for safety reasons," said Josee St-Onge, information office for Alberta Wildfire.

For some, it's an eerie reminder of the horror here in 2016.

Dubbed 'The Beast', the fire destroyed almost 2500 homes and businesses.

"As residents rush to leave their homes, I know that this will bring back difficult memories," said Alberta Premier Danielle Smith.

"This evacuation is a stark reminder that our province lives alongside the threat of wildfires and other natural disasters," she added.

For those in Fort McMurray tonight, there is some relief - for now.

Overnight rain has helped delay the fire's progress towards the city, known as a hub for Canada's oil output.

"We're graced with Mother Nature's kindness here today. We'll take as much rain as we can get on the fire," said one Alberta fire official.

Rain is forecast for the weekend, but there is a new risk: thunderstorms - which could ignite new fires. 

Fire and Emergency New Zealand said it hasn't been called to help, but it's still watching the situation closely.
