Extended Outlook
By the weekend high pressure and northerly winds to rebuild over Cape Mendocino at 25 kts, with windswell slowly regaining footing. But until then, no real windswell is forecast. Down south a small gale peaked late Sunday (7/8) in the Central Pacific with an infinitesimal area of 30 ft seas for 6 hrs aimed mostly due east. Low odds of small swell resulting on Wed (7/18). A stronger system developed barely off the Ross Ice Shelf Fri-Sat (7/14) with up to 44 ft seas, but all fetch aimed east and shadowed by Tahiti. Background swell from this one expected by the weekend (7/22). Another small system is developing under New Zealand on Tues (7/17) with 32 ft seas forecast pushing mostly east for 24 hrs.  Another shot of small shadowed swell possible. Nothing else is on the charts beyond.
