The North Pacific jetstream is actually looking better than it has for a while with a respectable flow pushing west to east over the dateline at 130 kts. A solid trough is forecast forming over the dateline pushing to the Gulf of Alaska with up to 190 kt winds flowing under it offering good support for surface level low pressure development. In response a surface gale is forecast forming north of HAwaii Tuesday (5/13) with 45 to near 50 kts winds developing for 24 hours generating seas in the 30-35 ft range for about 12 hours aimed well at California and points north of there. Possible swell to develop if all this occurs, but that is a leap of faith at this time. Down south a very quiet pattern is in effect with the jetstream split and displaced to the south, with the southern branch flowing over Antarctic ice. A cutoff low is forecast off northern Chile Mon-Wed (5/14) producing 40 kts winds aimed somewhat in to the California swell window but positioned well to the east, offering only minimal potential for Southern CA. Typhoon Rammsun peaked out on Saturday (5/10) 600 nmiles south of Southern Japan with winds to 135 kts, but too far away to have any real potential. It is already fading with further weakening forecast. No other swell producing systems forecast.
