marine weather discussion for N Pacific Ocean

NWS ocean prediction center Washington DC

1145 PM PDT Fri 4 Jul 2008

Forecast discussion: major features/winds/seas/significant

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

The qkscat pass from Fri evening continued to indicate 20 to 30

kt winds over the srn CA waters. Winds over the remainder of the

area were in the 10 to 20 kt range.

The 00z models were in very good agreement with the sfc pattern

through the fcst period. Plan on using the 00z GFS for the most

part. For the short term period through sun...cold front located

to the W of the WA/OR waters will move across the area

today...and eventually dissipate over the N CA waters later

today. All of the models are in good agreement keeping winds

below gale in advance of the fornt...and will maintain the 20 to

25 kt for the WA waters and 15 to 20 kt for the or waters for

today. During the Sun night through Wed period...thermal trough

will build N along the CA and or coast while high pres

strengthens W of the waters. Still looks like the onset of gales

for the N CA waters for later Sun afternoon looks good...while

adding the or waters beginning Sun night and continuing into

Wed. Brief period of gales for the central CA waters Sun night

and Mon looks reasonable.

Seas...for the most part we will remain close to the 00z ww3/enp

mdl guid for most of the...but add 1-3 ft to its guidance mainly

in/near the gale area later sun into Wed...with highest adj in

nrn CA wtrs.
