I wish the hyperbolic phrase "X is in fire" would stop.
The entirety of BC is not currently on fire (obviously). And if "BC is on fire" right now, then it would also be "on fire" when there is one single forest fire burning in the province.
Most of the major cities are inundated with smoke, and almost all of the cities are flooded with people fleeing the fires. The two major interior cities are completely surrounded by fire and subject to rolling evacuations.
