The ''Pineapple Express'' happens when warm air and lots of moisture are transported from the Central Pacific, near Hawaii, to the Eastern Pacific Ocean. An animation of satellite imagery from NOAA's GOES-West satellite showed the stream of clouds associated with that moisture from Dec. 9 to Dec. 12, 2014 and brought rain and snow to the western U.S.
