Environment Canada yesterday issued an August snowfall warning for a major BC highway. The Fort Nelson forecast calls for a long period of snowfall with totals amounting 8-12″. Further, it notes that the snowfall warning includes early-season heavy snow for part of the Alaska Highway.
The snowfall warning is also in effect for Muncho Lake Park – Stone Mountain Park.
The combination of an unseasonably cold arctic airmass and Pacific moisture associated with a low on the North Coast will result in continued heavy snow for higher elevations between Fort Nelson and Watson Lake. Total snowfall accumulations of 15 to 35 cm are expected through tonight. The town of Fort Nelson should receive rain while areas south of Fort Nelson may see up to 10 cm.
The forecast also calls 6-14″ of snowfall through today and tonight. The town of Fort Nelson should receive rain while areas south of Fort Nelson may see up to 4″, but the heavy snowfall is expected to ease Monday morning.

Travel is not recommended at this time because visibility may be suddenly reduced at times in heavy snow. Heavy snowfall accumulation may also cause tree branches to break.
