Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
1254 AM PST Tue Nov 20 2018

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

A weak, occluded low pressure system was analyzed over the
southern California waters near 31N 122W at 06 UTC. An earlier
ASCAT pass around 0445 UTC indicated southeast winds to 20 kt
associated with this system. Elsewhere, southerly winds are
strengthening over the PZ5 waters ahead of a cold front west of 
the area along 132W. A frontal wave will develop later today as 
the front nears the outer waters, and this low will track north 
across the outer PZ5 zones while gradually deepening tonight. 
Although the 00Z guidance offered mixed signals regarding the 
potential for gales, the GFS has consistently shown them for 
several cycles, including the 00Z run. Therefore, we will maintain
a brief gale warning overnight for our outer Washington waters 
as the low passes over the region.

The 00Z models converged on a slightly faster solution regarding
the strong cold front crossing the northern waters on Thu. In 
fact, all the global models now keep the occluded parent low 
well north of the offshore zones as the front races across the 
PZ5 and northern PZ6 waters. Beginning Thu, we transitioned our 
wind grids from the 00Z GFS to the 00Z ECMWF. The ECMWF/UKMET/NAM
all bring the front farther south than the GFS into the northern
California waters. The ECMWF has been more consistent in recent 
cycles and appears to match up better with WPC guidance as well.
Ultimately, this maintains gale warnings for all our zones north
of Point Arena, CA on Thu. 

The front will lift back north as a warm front Thu night ahead 
of a low pressure system expected to track across the southern 
PZ5 or northern PZ6 zones early Fri. Recent model trends suggest
gales are possible south of the low track, but for now the 30 kt
ECMWF solution serves as a good compromise between the stronger 
GFS/weaker UKMET solutions. A low pressure trough will cross the 
PZ5 waters later Fri, but the 00Z ECMWF/GFS/UKMET all keep winds 
below gale force at this time. Finally, another cold front will 
approach the northern waters this weekend with the potential for 
gales ahead of the front on Sat. Given the uncertainty at day 
five, we will confine gales north of the forecast waters until 
confidence increases. 


.SEAS...Wave heights are beginning to build over the northwest
PZ5 zones ahead of the approaching cold front. At 06Z, seas were
6-7 ft in this region and generally less than 6 ft elsewhere. In
the near term, the 00Z Wavewatch worked well with some minor 
edits along our coordination borders. On Thu, we transitioned to 
the 00Z WAM since the ECMWF winds were preferred through the 
medium range period. 


.EXTRATROPICAL STORM SURGE GUIDANCE...The 00Z ESTOFS and ETSS 
guidance show positive surge values to 1 ft or so extending 
along the Washington and northern Oregon coast on Thu. With the 
models coming into better agreement on the strong frontal system
described above, these values appear reasonable based on our 
latest wind forecast.


.WARNINGS...Preliminary.

.SYNOPSIS FOR WASHINGTON AND OREGON WATERS...A cold front W of
the area will continue moving E today as low pressure develops
along the front. This low will lift N across the outer waters
while gradually deepening tonight into Wed. A stronger low will 
approach from the W Wed and Wed night, then pass N of the area on
Thu while pulling a cold front across the region. The front will
lift back N as a warm front Thu night ahead of another low that
will cross the southern waters early Fri. A low pressure trough
will pass over the northern waters later Fri into Fri night. 
Another cold front will approach from the W on Sat and move
across the area Sat night.
