Coastal Flooding, Snow, and a Blustery Finish to the Week
It’s been an eventful Thursday across Newfoundland and Labrador — and the weather isn’t done yet.
This morning’s high tide coincided with a full moon and a persistent onshore flow, leading to significant coastal flooding in the Placentia and Dunville areas. That flooding was driven by a storm surge, with water levels pushed higher than normal thanks to both the recent powerful storm and astronomical tides.
As of this evening, storm surge warnings remain in effect for Placentia Bay and southern areas of the Avalon heading into Friday morning’s high tide. Further north, coastal flood statements have been issued for parts of Newfoundland’s north- and east-facing shores, and even into coastal Labrador. Model data from Environment and Climate Change Canada shows a 40–60 cm surge potential from the Southern Shore up through Trinity and Bonavista Bays tomorrow morning — meaning northern exposures may see the most impact this time.
While surge risk continues into Saturday morning, the magnitude will gradually ease. Still, with another low pressure system deepening in the North Atlantic and nearly a full moon, a repeat of minor coastal flooding in prone areas remains possible.
Snow In Eastern Newfoundland
As the new low pushes moisture in from the Maritimes, mixed precipitation has moved onto the Island. The rain–snow line this evening sits roughly between Sunnyside and the Isthmus, with Clarenville now reporting snow. On the Avalon, temperatures near 2°C are just cold enough for wet flakes to mix in, especially over higher terrain such as the Hearts Content Barrens and Portugal Cove–St. Philip’s area.
Live highway webcams confirm the trend — wet snow in Clarenville and Duns River, while Grand Bank and Salt Pond remain rain for now. By 9 PM, most forecast models indicate snow spreading across the Avalon and eastern Newfoundland, with light accumulations (1–3 cm) likely on grassy or elevated surfaces before tapering off around midnight.
Winds and Temperatures
Behind the departing system, expect gusts near 80 km/h across parts of eastern Newfoundland overnight, easing into Friday morning. While not as strong as Tuesday’s record-breaking storm, it’ll still be breezy at times.
Friday will be chilly, with highs of 3–7°C across Newfoundland and well below freezing in Labrador. Some flurries will linger early in the west before clearing to a mix of sun and cloud. The weekend looks quieter, with a modest rebound in temperatures — milder on Sunday and no major systems expected through that period.
In Labrador, expect a mix of rain and snow Saturday, turning cooler again Sunday, especially in the west.
A Look Ahead
We’ve now officially seen our first flakes of the season in parts of eastern Newfoundland — and for those watching the annual snowfall contest, today might just mark that “first centimeter.”
I’ll have my next update posted tomorrow morning!
