.Forecast discussion: major features/winds/seas/significant .Weather for the North Pacific N of 30n and E of 150w.
Latest Sat pix shows weakening cold front moving across the CA waters. The obs indicate seas generally 3-6 ft acrpss entire mim area with Max of 7 or 8 ft. The overall pattern over the epac has not changed much during the past few model runs. There is still the poss of gale conditions along nrn CA CST Thu into Sat night. My confidence that gales will actually occur across the offshore waters is low to medium however...as the strongest gradient remains in the coastal zones. The global models...in particular the GFS and ECMWF are in very good agreement throughout the period with just some minor differences in the bl winds. Ovr the next couple of days a coastal trof will strengthen and shift nortward along the CST. Max winds will likely be found in the coastal zone along nrn CA CST and extreme inner portion of inner adjacent offshore waters. Will continue to pop the wind grids using the GFS 10m throughout the period. Will enhance winds from Thu through Sat night along nrn CA CST by pop with 30m GFS winds during that period. Also in addition increased winds a bit in order to maintain continuity and get gale conditions along nrn CA CST. The ww3 looks good with only minor adjustments needed.
