MARINE WEATHER DISCUSSION FOR N ATLANTIC OCEAN

NWS OCEAN PREDICTION CENTER WASHINGTON DC

326 AM EDT TUE AUG 30 2016



.FORECAST DISCUSSION: MAJOR FEATURES/WINDS/SEAS/SIGNIFICANT

.WEATHER FOR THE NORTH ATLANTIC OCEAN W OF 50W FROM 30N TO 50N.



SUMMARY...00Z NCEP SFC ANALYSIS SHOWS T.D. EIGHT CENTERED OVER

ZONE 930 IN THE SRN NT2 WTRS...WITH T.D. NINE CENTERED ABOUT 90

NM NW OF WRN CUBA...HURCN GASTON IS CENTERED ABOUT 500 NM E OF

BERMUDA...AND A COLD FRONT EXTNDS NE TO SW ACROSS THE GEORGES BANK

AND SRN NEW ENGLAND WTRS. LATEST AVAILABLE ASCAT AND ASCAT HI-RES 

PASSES FROM EARLIER THIS MORNING SHOW AREAS OF WINDS TO 20 KT

ALONG THE NRN PERIPHERY OF T.D. EIGHT...THERE WAS NO COVERAGE OVER

THE CENTER OF THE SYSTEM. LIGHTNING DENSITY PRODUCT DATA AT 0650Z

INDICATES SCATTERED SHOWERS AND TSTMS OVER THE SRN ZONES OF THE NT2

WTRS...AND AROUND THE N AND NW SEMICIRCLES OF T.D. EIGHT.



MODELS...THE 00Z GEM/GFS/UKMET BRING A FAIRLY STRONG LOW NE ACROSS

THE NT2 WTRS ON THU AND THU NITE...WHILE THE 00Z ECMWF IS SIGNIF

SLOWER AND WEAKER WITH THIS LOW. THE 00Z GFS ALSO LOOKS CLOSE TO

THE OFFICIAL NHC TRACK FORECASTS FOR T.D. EIGHT AND T.D.

NINE...SO IT APPEARS THAT THE 00Z GFS 30M SOLN IS REPRESENTATIVE

ENUF TO BE USED FOR THE WIND GRIDS OVER THE ENTIRE FCST PERIOD. AM

NOT PLANNING TO MAKE ANY SIGNIF CHANGES TO THE CURRENT FCST

TREND...UNLESS THERE ARE SIGNIF CHANGES TO THE FCST TRACKS OF T.D.

EIGHT AND/OR T.D. NINE.



SEAS...00Z WNA WAVEWATCH III AND 00Z ECMWF WAM BOTH INITIALIZED

REASONABLY WELL OVER THE OFSHR WTRS...BUT IT IS POSSIBLE THEY MAY

BOTH BE A FEW FEET TOO LOW AROUND T.D. EIGHT. IN ORDER TO BE

CONSISTENT WITH THE PREFERRED 00Z GFS SOLN...WILL USE THE 00Z WNA

WAVEWATCH III FOR THE ENTIRE FCST PERIOD.
