The latest update from the B.C. Wildfire Service shows that a blaze east of Kamloops has reached 500 hectares in size.

That makes it about 20 percent larger than Vancouver's Stanley Park.

The East Shuswap Wildfire is classified as "out of control".

Four helicopters and four pieces of heavy equipment, as well as 89 ground personnel have been deployed to deal with what's being called an interface fire.

There are also air tankers ready to be used, if necessary.

Firefighters were able to save an eagle's nest, which was atop one burning tree. Enough water was dropped from the sky to douse the flames before they reached the eaglets.

According to the B.C. Wildfire Services, crews are mopping up hot spots near the edge of the fire and the north side is "fully machine guarded".

As the map below indicates, the fire is on the north side of the South Thompson River.

The Air Quality Health Index in Kamloops is expected to remain at 4 until 8 p.m., which indicates a "moderate risk". Under these conditions, people with heart or breathing problems are advised to reduce or reschedule strenuous activities outdoors if they're experiencing symptoms.

It will fall to 3 and then 2 later tonight and remain at 2 throughout Sunday (July 15). At these levels the at-risk population can enjoy their usual outdoor activities.
