Table of Contents
A powerful winter storm is poised to impact Newfoundland, prompting Environment Canada to upgrade coastal flood warnings and issue numerous alerts across the province. Residents are bracing for notable snowfall, high winds, and potential coastal inundation beginning late Sunday night and continuing through tuesday afternoon.
Widespread Alerts Issued
The weather service has issued an orange winter storm warning for the Avalon and Burin peninsulas, replacing a previous watch. This indicates a high likelihood of severe weather conditions. Elsewhere, wind warnings and blowing snow advisories are in effect for the south coast, specifically areas from Burgeo to Ramea, where near-zero visibility is anticipated.A yellow Coastal Flood Warning is also active for east and northeastern-facing shorelines from Cape Freels to Cape St. Mary’s.
Storm Details: Snowfall, Wind, and Coastal Surge
The Avalon Peninsula is expected to bear the brunt of the storm, with projected snowfall totals ranging from 35 to 50 centimeters (or more).Winds will gust between 80 to 100 kilometers per hour. Central Newfoundland can expect 15 to 35 centimeters of snow, accompanied by strong winds throughout the day. A senior official stated, “Along with the storm, it’s coinciding with the nearly full moon, so we will have elevated water levels with storm surge and also some wave action in those east to northeasterly winds, especially along east and north facing coastlines.” The combination of storm surge, wave action, and elevated water levels poses a significant threat to coastal communities. Rainfall is expected to be between 5 to 10 millimeters, primarily affecting the southern Avalon.
Why is this happening? A powerful low-pressure system, combined with a nearly full moon’s tidal effects, is driving the storm. the full moon exacerbates the storm surge, increasing the risk of coastal flooding.
Who is affected? The Avalon and Burin Peninsulas are under an orange winter storm warning, while the south coast faces wind warnings and blowing snow advisories.Coastal communities from Cape Freels to Cape St. Mary’s are at risk of flooding.
What is the impact? Significant snowfall, high winds, and coastal flooding are expected. Travel disruptions, power outages, and potential property damage are likely.
Travel disruptions Expected
Air Canada and Westjet have already issued travel advisories for flights to and from St. john’s International Airport (YYT) for both Monday and Tuesday. Travelers are strongly advised to check with their airlines for the latest updates and potential cancellations.
Coastal Residents Urged to Take Precautions
Environment Canada meteorologist Veronica Sullivan is advising residents along vulnerable coastlines to stay away from the shore. “Keep an eye out for elevated water levels and the potential for some damages due to coastal flooding,” she cautioned. Residents are encouraged to secure property and prepare for potential power outages.
those with cancellations are encouraged to email [email protected].
How did it end? As of Tuesday afternoon, the storm began to move east, diminishing in intensity. Snowfall tapered off, and winds gradually decreased. Though, coastal areas continued to experience elevated water levels and the risk of flooding remained. Cleanup efforts began, with crews working to restore power and clear roadways.
This developing weather system demands vigilance and preparedness from all residents of Newfoundland as the province prepares for a significant winter event.
