If you ever live in the path of a hurricane (or just care to read the NHC discussions) they refer to "Air Force Reconnaissance aircraft" or "NOAA Recon aircraft" depending on who it is who flew for that particular period. It seems like the WC-130's did the vast majority of flights that I read about during Ike and Dolly this year, FWIW.
The USAFR has 10 WC-130's, NOAA has 2 WP-3D's. Pretty easy to figure out why there are more WC-130 flights, even taking into account USAF crew rest rules.
