NWS ocean prediction center Washington DC
1245 am PDT sun 21 Mar 2010
.Forecast discussion: major features/winds/seas/significant
.Weather for the North Pacific N of 30n and E of 150w.
Still seeing some gale reports from the elevated stations
tatoosh and Destruction Island past few hours. Otherwise...sfc
data supporting winds below gale force currently across the nrn
waters...which is in line with latest guidance.
Models continue with a weakening trend in regards to the
gradient along the calif coast between the building high to the
NW and the cstl trof late Mon into Mon night. Models do show a
brief period where gales could still occur around 00z Tue...but
with the models trending weaker...will continue to keep winds
below gale force.
Differing solutions offered by the global models in regards to
strong low pres to psbly affect the nrn waters on Wed. Latest
ECMWF and GFS have trended more to the NW with the track of the
low and now take it just NW of the offshr waters. UKMET and cndn
continue to Show Low tracking E across the pz5 waters Wed as in
the prev runs of the GFS and ECMWF. Will keep fcst as is for now
and not change any headlines attm since the new GFS/ECMWF
solution has only had one model run. However...if it continues
to trend to the NW...may have to push gales to the N and W as
well.
Seas...wwiii looks reasonable across the cstl/offshr waters when
compared to latest sfc data. Will stay close to guidance for
this package.
Extratropical storm surge guidance...N/A.

subject to change. Any changes will be coordinated through AWIPS
