Daniel Swain for Nation World News — Pineapple Express Hurricane in California: it means this

UCLA climate scientist Daniel Swain discusses the Pineapple Express atmospheric river storms for Nation World News. Swain describes the upcoming weather pattern as a “true atmospheric river” and highlights its classification as a “Pineapple Express-type atmospheric river” originating from the tropical Pacific around Hawaii. “Storm number one will be moderate to intense. Nothing earth shattering. It will not be catastrophic, but it could cause widespread urban and river flooding in Northern California,” Swain said.
