Such
warnings are issued when fire weather meteorologists see conditions
that could lead to “blow-up fire behaviour,” said Derek Gagnon, wildfire
information officer.

“Fires will grow very rapidly and spread
very quickly, and that can pose a critical degree of danger to not only
our personnel but the public as well,” Gagnon said on Wednesday.

High
temperatures, low humidity, stronger winds and dry conditions on the
ground are all factors that contribute to a red flag warning, he said.
This is the second time such a warning has been issued for the Chuckegg
Creek wildfire. Similar warnings have been issued in connection with
other fires burning in northern Alberta, he said.
