Extended Outlook
The Madden Julian Oscillation (MJO) continues strongly in the Active Phase focused on the dateline and seeping east, expected to slowly decay over the next 2 weeks. It is to provide solid support for storm formation from the West Pacific easing east through then. Storm #21 formed Tues (2/2) west of the dateline peaking Wed (2/3) on the dateline with 44 ft seas. Swell expected in for late in the weekend. And another formed 900 nmiles off Central CA on Friday with 27 ft seas.  Swell from it expected to arrive for Sunday along with local windswell, resulting in a jumbled and confused surf pattern. Beyond Storm #22 is starting to build off Southern Japan on Sat (2/6) expected to slowly lumber its way east into the Gulf of Alaska early next week with seas in the 42-45 ft range targeting Hawaii and CA well. But all data continues to suggest that the remnants of this system will reorganize off the US West Coast forming 2 smaller storm pushing inland about as the swell from the original system arrives, making a mess of things.
