Good question. I keep on hearing in the media when they report on Pacific storms that 'hunters' are flying into them, so I would assume they make a refueling stop somewhere along the line.
Anyway I'd watch 13927USB (MARS freq) for phone patches, and make some occasional checks on the HF-GCS system. HF isn't a primary for the hunters - they will use SATCOM more, and I think they use HF as a backup. A check of the UDXF Yahoo group might turn up where they were heard with the last couple of hurricanes on the East Coast.
I would also keep an ear on the PAC group of MWARA freqs - diverting aircraft around these storms can sometimes be entertaining to listen to....73 Mike

updates and better freqs are, of course, always welcome
