marine weather discussion
NWS ocean prediction center Washington DC
1245 PM EST Sat 21 Nov 2009
.Forecast discussion: major features/winds/seas/significant
.Weather for North Atlantic ocean W of 50w from 30n to 50n.
Low pres currently E of the nt2 waters will move slowly NE today
and tonight. N to NE winds up to 25 kt will continue across
portions of the srn and central nt2 waters into tonight. Strong
high pres will then build N of the nt1 waters sun. Weak low pres
is still expected to form across the srn nt2 waters Sun
night...then track NE across the offshore waters through Wed.
The latest runs of the NAM and GFS are in reasonable agreement
and continue the idea of the last couple of model runs in having
somewhat weaker winds across the offshore waters. The
Canadian...meanwhile...continues to be a strong outlier. For now
will continue with previous forecast of showing Max winds of 30
kt with this system as it moves NE. A cold front will then move
into the offshore waters by Thu.
The wavewatch model looks reasonable and will be followed fairly
closely during the forecast period. The E swell which wavewatch
iii brings into nern nt2 waters as well as Georges Bank sun
ngt/Mon appears reasonable as global models all indicating
decent E to NE fetch N of W Atlc cold front.

subject to change. Any changes will be coordinated through AWIPS
12 planet chat or by telephone.
