The latest evacuation order issued due to a wildfire in British Columbia covers a rural area around 150 kilometres north of Prince George.  The regional districts of Fraser-Fort George and Bulkley-Nechako issued the order Monday night as the 10-square kilometre Ocock Lake blaze moves toward properties in the Noonlang Lake area, about 150 kilometres north of Prince George.  Several other orders and alerts in the province have been downgraded, including in the Kelowna area.  The B.C. Wildfire Service also announced Tuesday that the Rossmoore Lake wildfire south of Kamloops is now being held — which means it is not likely to spread beyond existing containment lines.  The blaze had led to numerous evacuation orders covering hundreds of people in and around the central Interior city earlier this summer. Firefighters are expected to remain onsite, however, to maintain existing protections.
