Yeah, I think this is the correct thinking. Latest roundy maps has the current wave croaking in 7/8. Then they start keying on a kelvin wave in p5. With lots of substance in p6, looks like it will head back towards cod then eventually a wave forms in p1/2.
As for the weeklies, we need to get that look inside day 7 for me to believe it. If the AAM relaxes then perhaps typical February nino takes over.
