.FORECAST DISCUSSION...Major features/winds/seas/significant 
.weather for the North Atlantic Ocean W of 50W from 30N to 50N.

Visible satellite imagery continues to impress this afternoon,
revealing the textbook structure and appearance of a 954 mb 
hurricane force low centered east of the offshore waters near 38N
53W. The imagery also shows widespread cold air cumulus 
streaming across all 18 offshore zones as modified arctic air 
spills offshore, with widespread strong gales persisting this 
afternoon across the vast majority of OPC zones. Earlier ASCAT 
passes confirmed the ongoing strong gales, and buoy and ship obs
along the Mid-Atlantic and New England coasts continue to show 
1-min winds at or above gale threshold. 12z models remain 
consistent a cold air low will develop across the Gulf of Maine 
and Georges Bank this evening, then track SE across the outer 
waters while intensifying beneath a digging shortwave and upper 
H5 low. There remains a persistent signal in the guidance for 
possible storm force conditions briefly across the Gulf Stream 
in the outer portions of Baltimore Canyon, and see no compelling 
reasons in the afternoon guidance to drop these warnings in the 
upcoming package. Based on those earlier ASCAT winds, the 12z 
ECMWF appears to have initialized conditions best, and will blend
in the wind-bias corrected version to update the near term
