I always reccomend using Chris Parker @ Caribbean
90% of the time he is right on and you can access him on SSB
or on the internet
beginning at 6:00AM Monday thru Saturday.
Have used Chris for over 10 years and crossed both oceans with his guidance and have been very satisfied.
If you shop around, you can find some weather site to tell you what YOU want to hear, not what is likely to be.
Look into Chris and listen to a few of his broadcasts
