Marine Weather Discussion for N Atlantic Ocean NWS Ocean Prediction Center Washington DC 333 PM EST Fri Jan 29 2021 .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 grids.
