South and southeasterly areas of the island experienced heavy rainfall, while a snow squall watch affected parts of the west coast.
Newfoundland Power reported a number of outages on the island, including South River, St. John's, the Southern Shore, the Burin Peninsula and several communities outside Corner Brook. The utility said "severe weather conditions" were the cause.
Wind warnings were issued across the island. With winds gusts hitting 154 km km/h in the notorious Wreckhouse area on Newfoundland's southwest coast, ferries around the island were tied up in port. For instance, Marine Atlantic kept its vessels from sailing across the Cabot Strait until the worst of the storm had passed.
In southern Labrador, conditions were so bad that the Department of Transportation and Works had to keep crews off the road for safety reasons.
Some roads in southern Labrador were also closed, including connections affecting Red Bay, Lodge Bay and Port Hope Simpson.
Further north, a blizzard warning covered the Labrador coast from Hopedale to Makkovik, while much of the interior was under a winter storm warning.
Meanwhile, Environment Canada was warning of a storm surge along western Newfoundland, particularly near Bay St. George and Port Saunders.
A snow squall warning was also covering Newfoundland's west coast.
The storm has been causing problems for air travellers, with flights cancelled between St. John's and both Deer Lake and Happy Valley-Goose Bay. Travellers were asked to check for updates with their carriers.
