NWS National Hurricane Center Miami FL
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
1. An area of low pressure is producing disorganized showers and thunderstorms over the tropical Atlantic several hundred miles east of the Windward Islands. Environmental conditions are expected to be favorable to support some gradual development, and this system could become a tropical depression while it moves west-northwestward at 10 to 15 mph. The disturbance is forecast to reach portions of the Lesser Antilles late Monday and then move across the eastern Caribbean Sea and Greater Antilles through the middle of this week. Interests in those areas should monitor the progress of this system, as it could bring locally heavy rainfall and gusty winds to portions of that area.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...medium...40 percent.
2. Showers and thunderstorms associated with an area of low pressure located over the tropical Atlantic about midway between the Cabo Verde Islands and the Lesser Antilles have become more concentrated since yesterday. Environmental conditions are expected to become a little more favorable for gradual development, and this system could become a tropical depression within the next few days. The system is forecast to move slowly toward the west-southwest or west during the next couple of days, and then move a little faster toward the west by mid-week.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...medium...40 percent.
3. Showers and thunderstorms associated with a broad area of low pressure located about a hundred miles west of the southwesternmost Cabo Verde Islands have diminished since yesterday. Strong upper-level winds and cooler waters are expected to prevent the development of this system while it moves toward the west or west-northwest.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...near 0 percent.
