Drivers are asked to avoid all travel on Highway 63 in both directions on Saturday morning due to snowfall creating impassable conditions. Wood Buffalo RCMP say “extremely poor road conditions” have left multiple vehicles, including semi-trucks, stuck on the highway north of Fort McMurray. “Traffic is at a standstill in both directions along various locations,” a news release from just before 9 a.m. said. Anyone driving in the Fort McMurray area should expect delays, Mounties added, and postpone travel if possible or check 511 for up-to-date road information. Environment Canada issued a snowfall warning for northeastern Alberta, including Wood Buffalo, on Friday afternoon. Officials were calling for 10 to 15 cm of snow. Precipitation was expected to taper off Saturday evening.
