The Thomas Creek Wildfire has swelled to over 1,100 hectares in size.
Since Tuesday morning, the out-of-control fire grew another 200 hectares in size.
More smoke has moved into Penticton Tuesday afternoon.
The fire had initially been producing heavy smoke that made accurate mapping difficult, according to the BC Wildfire Service.
Currently, over 700 properties in and around Okanagan Falls are under an evacuation alert issued by the Regional District of Okanagan Similkameen.
The RDOS had rescinded their earlier July 11 order of evacuation for 77 properties, and included them in the current alert.
The cause of the fire is still under investigation.
Heavy equipment is currently deployed on the fire’s southwest corner, the direction closest to properties in Okanagan Falls, and working upslope.
In addition to the heavy equipment, 30 firefighters and six helicopters have been assigned to the fire.
The fire was initially reported at 0.5 hectares when it was first spotted Sunday.
