SAVONA, B.C. - More firefighters are expected to arrive in an area west of Kamloops, B.C., to help contain an aggressive wildfire that scorched a square kilometre of grassland, sage and bush within hours.

The blaze, which is believed to have been started by humans, broke out near Savona Wednesday, severing Highway 1 between Kamloops and Cache Creek

Crews were able to reopen the highway after the flames responded well to suppression efforts.

Several aircraft were assigned to the fire Wednesday, but strong and gusty winds complicated the work.

At one point, the flames had burned below power lines cutting electricity to about 400 customers, but the BC Hydro website shows power was restored within hours.

Environment Canada reports a “precipitation deficit” in the Kamloops area after an extremely dry spring and even the five to 10 millimetres of rain expected across the region this weekend won't be enough to erase the parched conditions.
