Should be fine. Once you get w/in about 200 miles you will likely be
in the skip zone of the Hawaii faxes. However, you'll get VHF weather
the next day, so it usually is no big thing. If you are a Ham (I
presume you are with that rig) then you might check in with the pacific
seafarer's net -- 14300 @ 0300Z. If you are in a jam or need special
wx info someone (often Don N6HG) will probably be willing to troll the
net for what you need.

Have fun!
