 The CPHC previously tasked with monitoring tropical activity in the basin was originally known as the Joint Hurricane Warning Center; today it is called the Joint Typhoon Warning Center.Central Pacific hurricanes are rare and on average 4 to 5 storms form or move in this area annually.As there are no large contiguous landmasses in the basin, direct hits and landfalls are rare; however, they occur occasionally, as with Hurricane Iniki in 1992, which made landfall on Hawaii, and Hurricane Ioke in 2006, which made a direct hit on Johnston Atoll.
