Keep your eyes on this area and any developments. In the southwestern Caribbean Sea an area of low pressure is likely to develop over the next day or so. Gradual development is possible and a tropical depression could form late this weekend or early next week.
Formation chance through 48 hours is now 40 percent and the formation chance through 7 days is up to 80 percent.
Northeastern Caribbean Sea and Greater Antilles: A trough of low pressure located near Puerto Rico is producing a large area of showers and thunderstorms over portions of the Greater Antilles and the adjacent waters of the Atlantic and the northeastern Caribbean.
Slow development of this system is possible during the next few days, after that the system is expected to be absorbed into the low pressure area over the Caribbean.
Formation chance through 48 hours is low at 10 percent and the formation chance through 7 days is also 10 percent.
North Atlantic: A low pressure system located a few hundred miles west of the Azores has been producing increased convection near its center over the past few hours. Satellite derived wind data depicted winds to storm-force mainly to the south of the the center.
Environmental conditions appear favorable for some additional development and the system could become a subtropical or tropical storm as it moves generally eastward during the next few days.
Formation chance through 48 hours has increased to 50 percent and through 7 days.
