Rising waters continue to cause concerns about flooding in several communities on Newfoundland's west coast on Thursday.

The RCMP in Channel-Port aux Basques said the Trans-Canada Highway in the South Branch area will remain closed.

The duration of closure is unknown.

Roads in the area have been affected by high water levels, which has caused the road to wash out beneath the pavement.

Police said repairs to the road will not begin until weather conditions improve. Engineers with the Department of Transportation and Works are at the scene and are assessing damage. 

In Corner Brook, heavy equipment was brought in to deal with pockets of flooding caused by rainfall on top of a buildup of snow. 

Public Works crews in the city continue to remain on alert. While water has started to recede in some areas, the rain has not stopped.

Crews are assisting with the re-opening of Candow Drive, which washed out on Friday morning, isolating residents of a trailer court.

Petries St. has been re-opened, but the Main Street Bridge remains closed as a precautionary measure. City officials have advised motorists to choose alternate routes.

As soon as the water recedes to safe levels, crews will begin removing debris from streets, and reinstating shoulders where required.

Thousands of people on the west coast and Northern Peninsula woke up in darkness on Thursday morning, although power was restored to most within hours. 

Newfoundland Power was still reporting outages in the Humber Valley, including parts of Pasadena, Humber Village and Steady Brook, as of 9:30 Thursday morning.

Newfoundland and Labrador Hydro, which reported outages stretching from Cow Head to St. Anthony, was able to put 2,400 customers back on power through diesel. Repairs were made later for other communities. 

Fierce winds, associated with a storm that already has battered the Maritimes, have swept into Newfoundland, with a peak gust of 142 km/h already reported at the notoriously windy Wreckhouse area on the island's southwest coast.

The Newfoundland and Labrador government issued a warning to residents to be cautious near coastal areas, where pounding waves could pose safety issues.

Western and northern Labrador can expect heavy snow during the storm.
