The MJO is moving from the Active Phase to the Inactive Phase signaling a less favorable environment to support storm formation across the North Pacific in the weeks ahead. But for now, the final push of the Active Phase is occurring as it track over the East Pacific. Storm #2 has developed about as expected in the Northern Gulf on Thurs/Fri (11/6) with 50-55 kt winds producing 40 ft seas targeting mostly the Pacific Northwest. Even a short bit of limited sideband energy is expected for Hawaii on Saturday. Beyond a secondary gale is forecast right behind in the Gulf on Sun/Mon producing a small area of 45-50 kt northwest winds and up to 35 ft seas, but again targeting only Pacific Northwest with no energy expected for the Islands. A possible cut off low is forecast forming just north of Hawaii early next week with 40 kt wind and 26 ft seas, aimed a bit west of the Islands. At least it's something to monitor.
