The Double Bomb Nor'easter- 03/26/2014

In a winter ripe with Atlantic storms, Nor'easter's and blizzards, the latest rendition was historic. A wind gust of 129 mph was measured on Wednesday at the Bay of Fundy

Storm systems are generally measured in two ways; wind speed and barometric pressure. Barometric pressure is commonly measured in millibars(mbar): with sea level being 1013.25 mbar and 1 bar= 14.5 psi. Numbers above 1013 mbar are considered High Pressure, whereas below 1013 mbar are termed Low Pressure. The lower the pressure= the stronger the storm. If 0 millibars= perfect vacuum, think BLACK HOLE. The most historic (of recent times) Nor'easter is definitely, the Halloween "1991 Perfect Storm", for which a Hollywood film was made, depicting the final voyage of Andrea Gail; a fishing boat lost in the storm. The Perfect Storm had a registered pressure of 972 mbar, Wednesday's 'Double Bomb Nor'easter' was registered at 955 mbar.
I went to during the height of the storm, to see if any ships were bearing the storm. As I scanned the map for any ships close to the Double Bomb storm center, I see only ONE single vessel in the entire North Atlantic maritime region. I figured it was probably a 1000 ft container ship, plowing the (~75ft) seas on a transatlantic voyage, nope.
As I zoomed into the map, I notice the 'ship' is close to this small landmass out in middle of the ocean, east of Nova Scotia, called Sable Island. I click on the small vessel icon to see the track.
Now, it all makes sense:
The 81 meter/261ft Panuke (below pic); a heavy duty, North Atlantic supply vessel, was taking refuge in the protection of the crescent shaped, Sable Island. a small blip of a sandbar, nearby its destination, the Thebaud natural gas platform. Mind you, the above screen capture was taken yesterday, 24 hrs later, and the Panuke, remains there today, jogging in little circles, two days later.

As I talked with a friend who works in the maritime industry last night, I told him about the offshore supply 'boat', jogging behind this tiny island 150 km east of Nova Scotia (in the heart of the stormand asked if he'd ever heard of Sable Island, to which he responded, "That's the Island the Andrea Gail was trying to get to during The Perfect Storm"....

Wow, that sure is something! Very informative, interesting, and impressive storm information. Thanks, Mark!

A good name for the movie could be "Run for Sable Island"

Good call, or a great song. it's reminiscent of "Seven miles to Murdo"!
