I see you have added a radar overlay. You are showing radar out of Puerto Rico. The French have radar stations in Martinique and Guadeloupe. http://www.meteofrance.gp/previsions-meteo-antilles-guyane/animation/radar/antilles
Thank you for the info.
Caribbean radar mosaic (provided by MeteoFrance) will be very usefull as hurricane "Irma" aproaches the area.
