System NHC Once Watched For Trop Development Becomes Tempest Off Newfoundland

There are not one but two systems dominating the weather on the North American east coast. The first is a newly developed coastal feature off New England which is bringing rain from DC to New York and a wintry mix to Boston while more significant snow is impacting the interior Northeast and New England.



As you can see, temperatures are borderline even over New England while it’s too warm for the Big Cities.



However, the big storm capturing our main attention is a huge wheel of wind, wave, snow located east of Newfoundland.

The same system which the National Hurricane Center was watching just a couple of days ago for potential rare March development is now a beast east of Newfoundland and is doing strange things.

Despite being some 400 miles to the ESE, this intense system has drove 70 mph ENE winds and heavy snow into eastern Newfoundland creating blizzard conditions.

More to come through Saturday…

Also, the ENE wind direction has forced sea ice north side of the Avalon Peninsula into east facing harbours including St John’s.

Amazingly the storm was far enough off Newfoundland that while the east of the island was pummelled, the WNW was largely unscathed.

Further WNW and on the Canadian mainland, beneath a clear, COLD sky of western Labrador, Wabush dipped to -29.3C.
