SUMMERLAND, B.C. - Evacuation orders and alerts have been issued by two regional districts in British Columbia's Okanagan Valley as wildfires flare following lightning storms and several days of withering heat.

The Regional District of Okanagan Similkameen declared a state of local emergency and issued two evacuation orders overnight for a total of 43 properties, several campgrounds and a provincial park along Highway 97 between Summerland and Peachland.

Those orders are in addition to evacuations issued Wednesday by the Central Okanagan Regional District for properties just north of that area along the west side of Okanagan Lake, south of Peachland.

The BC Wildfire Service says the lightning-caused Mount Eneas wildfire has scorched about two-square kilometres of bush in steep terrain about four kilometres south of Peachland.

Evacuees are being directed to reception centres in West Kelowna and Penticton and Drive BC says although Highway 97 was closed by the fire overnight, the route has reopened to single lane alternating traffic, with an RCMP escort.

An evacuation alert is also posted for a second wildfire, the Good Creek blaze, estimated at about two-square kilometres, burning across Okanagan Lake, in Okanagan Mountain Provincial Park just outside the southern limits of the City of Kelowna.
