Most of the snowfall will occur over a period of three to six hours, according to Environment Canada.
Cold temperatures are expected to accompany the system, with low temperatures overnight down to around minus six with a wind chill of minus 11.
It comes on the heels of several days of heavy snow throughout the region, which caused significant problems for local road crews.
Conditions on the area’s roads improved considerably on Tuesday 28 December and until Wednesday with no further congestion to deal with.
Local highways in the Nanaimo region were partially clear with salt, carrying sidewalks in one lane and compacted snow elsewhere.
Many major side roads were also treated as trucks moved into several residential areas.
“Crews have been out uninterrupted since Christmas Eve and maintaining priority 1 routes,” said a statement from the town of Nanaimo. “Local roads are packed with snow and winter driving conditions continue. “Residents can expect that the local roads will remain packed with snow for the foreseeable future, as temperatures remain well below freezing.”
Priority 1 routes include emergency and main roads, priority 2 roads are secondary corridors, while the last priority is dead ends for niche residents and dead ends.
Nanaimo Airport’s monitoring station recorded 38.6 centimeters of snow between December 23 and 27, but more congestion was noted within Nanaimo’s city limits and parts to the north.
Residents in many areas observed well over 50 centimeters.
The extended weather forecast for the center of the island continues to see unstable conditions into the new year, but temperatures should return above zero with snow turning to rain.
