I'm leaving for CSA in a week and I'm wondering which source for weather has proven to be the most accurate? I've been to CSA and the Caribbean a number of times and know that rain showers are usually brief and often times welcomed. However, there have been a few occasions when its rain heavy for a couple of days!

The reason Im even curious is because were bringing another couple with us on this trip who has never been to CSA or Negril and theyd like to do a few things off the resort, e.g., private catamaran cruise, YS Falls, horseback riding, etc. Were trying to determine which days to schedule which events based on what the weather will be like. Also, if it rains on Friday, wed like to plan to go to Ivans for dinner since the Shipwreck Beach Party would be moved from the beach to the Palms.

Which site (weather.com, wunderground.com, accuweather.com, the weather channel, etc.) has proven to be most accurate for you?
