"It certainly will increase in size today, and it's still listed as out of control and the conditions are still very dry. We do have some difficult weather, some interesting weather, coming up," said Matthew Anderson, wildfire information officer with Alberta Agriculture, speaking from Edmonton on Sunday.

"There's another cold front coming through and ahead of that front it's going to be very gusty, so this morning that could cause some significant growth as the winds shift and move through," he told CBC News.

"However, behind it, it's bringing cooler temperatures, at least by 10 degrees, perhaps dropping, and the humidity is increasing as well."

Anderson it's not uncommon for a fire of this size to burn for months.

Unless there's a significant rain event of 100 mm or more, we expect to be fighting the fire for months to come, says firefighter

"There are a lot of hotspots and the entire area that is affected, the size is double the size of Calgary, will have to be checked by crews ... so it's going to be quite a long process and a lot of gruelling work," he said.

"We would need a significant amount of precipitation to really help to bring things under control a bit more," Anderson said, adding what little rain is expected may reach the fire zone or just fall farther north.

The province's meteorology branch predicts a chance of a small amount of snow on Tuesday or Wednesday because of the approaching cold air mass.
