marine weather discussion for N Pacific Ocean

NWS ocean prediction center Washington DC

735 am PDT sun 20 Jul 2008

Forecast discussion: major features/winds/seas/significant

weather for the North Pacific N of 30n and E of 150w.

The 06z runs of the GFS and NAM look to be in reasonable

agreement the next few days. High pres W of the pz6 waters will

combine with thermal trof across California to produce mainly N

to NW flow over the offshore waters. Strongest winds currently W

of Cape Mendocino will continue to weaken today. The strongest

winds will then shift slightly S by Tue with minimal gales still

expected across portions of the nrn and central California

waters Tue into Wed.

Farther N...one cold front will weaken as it approaches the

Washington waters today. Another weak cold front will then

approach the pz5 waters by Thu.

Compared to the 12z sea state analysis...the ww3 seems to have a

reasonable handle on the seas and will be followed fairly

closely for the forecast.

Warnings/forecast confidence...preliminary. Any changes will be

coordinated through AWIPS 12 planet chat or by telephone:
