Energy off the East Coast of the USA will be set to sweep off-shore and close to Nova Scotia and Western Newfoundland.
Key Updates as of 04/07 @ 6:15PM
Confidence is quite high that a significant snowstorm will move into the region of Atlantic Canada, and target most of Nova Scotia (including Cape Breton), eastern PEI, and Newfoundland (mainly Western Newfoundland).
Overall snowfall totals for impacted regions (as per our map above) can be expected in a range of 15-25cm. We at TCW expect regions 10-20km inland from the Western Newfoundland shoreline as well as 5-10km inland from the NW Cape Breton shoreline to reach 25-40cm of snow.
New Brunswick will be largely non-impacted from this system.
SW Nova Scotia will experience a snow/rain mix.
Central Newfoundland will experience a mix of snow and prolonged light freezing rain, while eastern Newfoundland will experience a wet snow/rain/light freezing rain mix.
**Note: There is some potential some localized regions in south-central and central Newfoundland (roughly 20km N/NW of Burgeo and extending to Grand-Falls-Windsor, to receive around 10-15cm of snow as well as 8-15mm of freezing rain). Elsewhere, light freezing rain risks exists, but the accretion will be half or less than the aforementioned accretion.
Conditions can colloquially be phrased as “calm before the storm”, with relatively calm conditions.
Conditions will begin to slowly deteriorate for SW Nova Scotia very late Saturday Night.
Conditions will deteriorate through much of Nova Scotia by the pre-dawn.
Conditions will deteriorate through much of PEI and Cape Breton by the afternoon.
Sunday Evening (6pm MST)
Conditions should improve (progressively) for most of the Maritimes and conditions will deteriorate across Newfoundland.
Conditions will slowly improve all-together for the Maritimes.
Conditions will slowly improve all-together for Newfoundland.
Watch for gusty winds and local blowing snow.
Please stay tuned, as we at TCW are monitoring this situation attentively.
