Officials will be deciding on Friday whether a widespread ban to accessing the backcountry in the B-C Interior is necessary to help mitigate wildfires. Warm, dry conditions have persisted throughout the province, and forecast thunderstorms could bring more lightning that has already been causing new fires to spark. The B-C Wildfire Service says human-caused fires must be avoided in the coming weeks so crews can remain focused on the naturally occurring ones. The ban would apply to the Cariboo fire centre and the final decision will depend on wind conditions.
