Powerful Atlantic Storm Getting Stronger

An Atlantic storm is rapidly strengthening off the East coast bringing blizzard conditions to the New England coast.

A storm, equatable to a hurricane, is paralleling the East coast and headed towards the Canadian Maritimes.  Check out this incredible streamline map that shows the tight circulation surrounding the deepening low.  As of 8:30am, the pressure has dropped to 963mb.

That pressure drop was 50 mb in just 24 hours. It's more that double the rate needed to be defined as a "cyclone bomb."

Here's another view of the storm from the GOES East satellite.  It is a classic cyclone.  Notice the comma shape on the right side of this image.

And this visible satellite image shows the center of the storm along with snow cover here in Washington, D.C.

To be clear, this Northeastern powerhouse storm is the same one that brought us 1-4" of snow yesterday.  New England's coast is catching the brunt of the storm right now.  Blizzard warnings are in effect for Cape Cod and coastal Maine.  Heavy, blowing snow will reduce visibilities to less than a quarter mile.   Winds will gust between 70-80mph along the coast.  Hurricane force wind warnings are in effect off Cape Cod (mauve color).  You could coin this a "snowicane!"

To get a sense of what this looks like, check out this video from Chatham, MA. 

As of 8:30am Wednesday, a 78 mph wind gust was reported at Nantucket, MA. Heavy snow continues to fall along the coast.

Wave heights have exceeded 8.5ft in Nantucket. The wind is pushing the water onto shore, so coastal flooding is another concern, along with the snow and damaging wind gusts.  Snowfall totals close to a foot are expected in the blizzard warned areas on the cape. But there is a very sharp gradient between getting clobbered by this storm and getting off easy.  Roughly 50 miles away in Boston, just an inch of snow is expected at most.

Fortunately, this epic storm is far enough offshore the most severe impacts are only felt along the extreme coast of New England.  Nova Scotia, Canada will get hit hardest. The rest of the Northeast and Mid-Atlantic are being impacted with gusty winds.  As high pressure moves in from the west, the pressure gradient between the high and low create windy weather in our area.


This is an epic storm and proves the sheer strength and power of weather. Thanks to Jacqui Jeras for some editing and adding to this blog post.
