Snow is expected to develop today and continue through Thursday morning with the heaviest snow occurring overnight.
Snowfall amounts will range from 5 cm to 20 cm. The heaviest snow will likely fall in the Big Trout Lake and Peawanuck area.
Travel will be difficult due to the accumulating snow and visibility will be somewhat reduced.
