Waves are one of the most difficult things to forecast. They can grow rather quickly or fall apart just as fast. I've seen good looking waves over the Bahamas heading in our direction full of moisture, only to fall apart overnight and have no impact on us what so ever.
So having said that, I'm giving you a heads up on a wave impacting Jamaica, Cuba, and Eastern Bahamas.
On the image above you can see the cloud cover over that area. The deep blue and red colors represent heavy rain. It already dumped plenty of rain over the U.S. Virgin Islands and Puerto Rico. They had been under Flood Advisories while Dominican Republic and Haiti have also alerted their residents to the threat of flooding.
This feature is now splitting in two, the wave across the Caribbean and a disturbance over Eastern Bahamas.

If the wave is still around by Tuesday, expect plenty of tropical rain to move over the islands with the possibility of flash floods. For us, the disturbance will probably arrive here on Wednesday providing more tropical rain.
