Marine Weather for HS 100

Forecast

marine weather discussion for N Atlantic Ocean NWS ocean prediction center Washington DC 237 PM EDT Thu Oct 30 2014

.Forecast discussion: major features/winds/seas/significant .Weather for the North Atlantic ocean W of 50w from 30n to 50n.

Cold front currently moving across the offshore waters will move E of the nt1 and nrn nt2 waters today while becoming stationary across the srn nt2 waters. Low pres is still expected to form tonight and early Fri off the se coast and then move NE across the offshore waters Fri into Sat. The models have been trending stronger with this low which would bring gale conditions into the New England offshore waters by Sat. Another stronger low is still expected to form off the Carolina coast by Sat and also move NE across the offshore waters. The models have been trending weaker with this low but should still be strong enough to produce storm conditions across the central nt2 waters by Sat night while the nrn nt2 and nt1 waters would have gale conditions. The low will then move into the Canadian Maritimes by sun. The 12z runs of the GFS and UKMET are in reasonable agreement with the track and strength of both lows. Main change to warnings will be to have gale conditions instead of storm across the nrn nt2 and nt1 waters by Sat night and sun.

The wavewatch looks reasonable with the seas and will be followed fairly closely during the forecast period.

Extratropical storm surge guidance...the models continue to forecast a negative surge of 0.5 to 1.5 ft for Fri night into Sat night along the se coast.
