Outlook
Up some maybe ---

A gale developed under New Zealand on Fri (9/3) producing 36 ft seas aimed east-northeast producing the first pulse in a 3 pulse swell. Pulse #1 is gone. The gale pushed to the Central South Pacific on Sun (9/5) while rebuilding through Mon (9/6) with 39 ft seas aimed well northeast producing Pulse #2 which arrived on Mon (9/13). And Pulse #3 was right behind building over the Southeast Pacific on Tues-Wed (9/8) producing 41 ft seas aimed northeast. Swell arrived starting on Tues (9/14). Nothing is forecast beyond from the south. But 3 gales are forecast traversing the North Pacific over the next week with the later 2 possibly producing 20 ft+ seas. Something to monitor.
