Infobox Hurricane Small
Basin=EPac


Track=Norbert 1984 track.pngFormed=September 14
Dissipated=September 26
1-min winds=115Norbert was a hurricane that took a truly bizarre path.

Norbert then turned east again before accelerating to the northwest. It recurved slightly and it dissipated before making landfall in Baja California.

Norbert, although never striking land, was the first Pacific hurricane to perform such a track as it did, and also was the only Pacific hurricane to reach Category 4 strength on 4 separate occasions.
