Here is an extract from GCaptiain's blog:
Last weekend saw an unusually intense hurricane force extratropical storm low over the North Atlantic. An active weather pattern started showing up on computer models more than a week earlier and by the 21st, the official NOAA “96 hour North Atlantic surface forecast chart” showed a rapidly deepening 977mb storm low over the central North Atlantic for 12Z Friday January 25th moving northeastward with a forecasted central pressure dropping to 933mb by 12Z on Saturday the 26th!
