The weather guru du jour in the Florida/Bahamas area is Chris Parker. He has a Single Sideband broadcast daily (except Sunday) morning and evening and is also available online. You can listen for free, although his rates are not outrageous. He starts with a daily weather prognosis, and then gives custom forecasts for the paying customers. There is usually someone close to you, so you can piggyback on the forecast. We found him to be conservative in his estimates, so the winds were never as strong as forecast. Weather in the Bahamas is a big deal, especially in the Out Islands, as there are few all weather anchorages, which results in a lot of scrambling before a cold front passage. Enjoy your trip.
