Chris Parker of the Caribbean Weather center is very popular for boats cruising the Caribbean. Daily he provides voice weather forecasts via SSB radio. If you are a "sponsoring vessel" (i.e. you pay) you can speak with Chris directly about specific weather for your planned passage. For an additional fee you can also subscribe to daily weather forecasts via email. We find these services highly valuable.

Here is a typical forecast that we would receive via email:
