You can find Cuban radar (when it's available), at Cuban Radar

I am having trouble getting in to their site, so it's probably being overwhelmed with traffic from the net.

Just one comment about the FSU model. I agree with others on this one. If it's patented, they are legally protected from people stealing their proprietary system. There's little reason to keep the data so restricted from the general public - and less reason to keep the data from college degree'd professional meteorologists without hefty $30K price tags. I can maybe understand not letting Joe Public see it, as people without knowing about models may believe in an experimental model over the official, professional NHC directives. But to keep folks like JK (great initials, by the way, same as mine, heck, same first name even), Clark, etc from having access without the big money is ludicrous. Patent it, protect it, and keep getting your money from the government. It's things like this that start conspiracy theories...

Just to have some value to my post, don't forget you can also check buoys in the Caribbean at Buoy Reports Grand Cayman is starting to get gusty winds, according to the most recent buoy reports.
