The first set of WC-J130s, also known as �Hurricane Hunters,� arrived today at Hickam Air Force Base.

The Air Force Reserve planes came from Keesler Air Force Base in Biloxi, Miss., and will be used to track Hurricane Felicia.
A total of five will be sent to Hawaii but only four will be put in service. Every 12 hours one plane will take off in a 48- hour rotation.
Meanwhile, the National Weather Service will use a smaller aircraft to drop instrumentation near Felicia starting tonight.
