Weather Underground Forecast for Thursday, May 23, 2013.

While tropical cyclone development is not anticipated in the tropical Atlantic Ocean on Thursday, areas of unsettled weather will develop in the Caribbean Sea and neighboring islands. High pressure north of the Caribbean Sea and a tropical wave crossing the southwestern corner of the basin toward southern Central America will maintain moderate to fresh trades across much of the Caribbean basin. Ample moisture and energy streaming across islands just north of the basin will create chances of light to moderate scattered showers and chances of thunderstorms in the Bahamas, Cuba, Hispaniola, Puerto Rico, and Jamaica. Meanwhile, more robust showers and with chances of thunderstorms are anticipated in the southwestern corner of the basin and across Panama, Costa Rica, and Nicaragua due to the approaching tropical wave and the proximity of the monsoon trough.
