A historic extratropical storm is possible over the central North Atlantic on Saturday, the 26th of January based on the latest computer models. A weak 1014mb low will move off the Virginia and North Carolina coasts early Thursday. It will move rapidly east to northeast, deepening to a 977 mb storm low by 12Z Friday, the 25th, southeast of Cape Race with winds up to 50 knots. Thereafter, this low is forecast to “bomb out” as it moves northeast, dropping 57 mb of pressure to 920 mb by 12Z Saturday, the 26th, with hurricane force winds of 85 knots (nearly 100 mph) likely.

The all-time record for North Atlantic extratropical storms was the Braer Storm of January 1993 that reached a minimum pressure of 914 mb (26.99 in Hg) on January 10th. The 1993 storm caused blizzard conditions across much of Scotland and also led to the final breakup of the oil tanker MV Braer, which had been stranded in rocks off the Shetland Islands by a previous storm.

ARRGGGHHHH! Run AWAY!

Update: A 1003mb low off the Middle Atlantic Coast this afternoon will move and deepen very rapidly as it tracks northeastward with winds forecast up to 50 knots this evening, reaching upwards of 60 knots by 12Z Friday and as high as 80-85 knots possible Friday night. Waves associated with this low will buildup to 17 meters (56 feet) by early Saturday. This system will likely deepen to near historical levels with models suggesting a minimum pressure of about 923mb early Saturday.

I hope everybody out there manages to stay well clear and no vessels are lost!

You have to be careful of these “double yokers”, the two or more lows. For one, I think in complex situations the models are not as reliable. For another, small differences in the relative positions of the two lows can make a significant difference in the fetch. If the lows line up right you can wind up in the wrong corner of the fetch table. The end of a 1000 mile long stretch of 70 kt winds is not the place you want to be.
