Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
101 AM PDT Wed Jun 26 2019

.FORECAST DISCUSSION...Major features/winds/seas/significant
.weather for the North Pacific N of 30N and E of 150W.

The 06Z surface analysis indicated low pressure over the far
southwest Washington offshore waters, with dissipating occluded
front extending across the Washington and Oregon coastal waters,
with cold front across the northern California waters. The latest
Ascat passes from 0440Z and 0620Z indicated a small area of 25 KT
winds west of the Washington waters, with another small area over
coastal waters northwest of San Francisco Bay area. There was a
large data void area over much of the California waters, however
the available retrievals did match up well with the model
forecast fields.

The 00Z models remain in very good agreement through the forecast
period. No warning headlines are expected into early next week as
overall winds remain light. The low pressure over the Washington
waters will drift slowly southeast across the Oregon waters
today, before dissipating late this afternoon or evening. The
models then indicate weak trough persisting across the
Washington/Oregon waters into early Saturday, while high pressure
ridge builds slowly toward the California waters. With the very
good model agreement, plan on using the 00Z GFS to populate wind
grids throughout. Although there are some slight differences
regarding a low pressure west of area early next week, these
differences have little impact on the offshore and coastal
waters.

.SEAS...The 06Z sea state analysis indicated that observed seas
continue to match up well with the WaveWatch forecast values, and
plan on using the WaveWatch to populate wave grids.

.EXTRATROPICAL STORM SURGE GUIDANCE...N/A.

.WARNINGS...Preliminary.

.PZ5 Washington/Oregon Waters...
None.

.PZ6 California Waters...
None.
