I believe an El Nino event is normally responsible for an active Pacific theatre and a calm Atlantic theatre? The system I'm watching right now is Genevieve; If it reaches the Western Pacific, would it qualify as a system that's crossed all three Pacific Zones, or would it have to have been constantly monitored (in other words, not declared post-trop)?

EDIT: Super Typhoon Halong is looking pretty impressive on satellite imagery right now. Currently forecasted to affect the Ryukyu's as the equivalent of a Cat 3 Storm and then possibly Japan afterwards.
