Tropical disturbance to approach Leeward Islands this weekend

Tropical Depression Four has weakened to a batch of disorganized showers and thunderstorms and will pass north of the Leeward Islands this weekend.
The area of disturbed weather will take a west-northwestward path over tropical waters over the next few days. The showers and thunderstorms are being guided by a clockwise flow associated with a large area of high pressure over the central Atlantic to the north.
The disturbance is moving into a zone of dry air and strong southwesterly winds at mid-levels of the atmosphere, according to AccuWeather Meteorologist Brett Rossio. This contributed to the system weakening.
The core of thunderstorms associated system will steer north of the Leeward Islands and Puerto Rico this weekend. However, it is possible for very spotty squalls to push westward across the islands.
The disturbance could still raise seas and surf around the islands. As a result, bathers and boaters should exercise caution.
The poorly organized feature may drift westward across the Bahamas, Cuba and the Florida Peninsula with spotty showers and thunderstorms next week.
As weak and poorly organized as the disturbance is, interests from the northern Islands of the Caribbean to the Bahamas, Bermuda and the southeastern U.S. should monitor its progress.
New system in Atlantic needs to be watched
In many ways, the tropical Atlantic is behaving more like mid- to late-August, rather than early July.
Many batches of showers and thunderstorms continue to roll westward from Africa.
One particular large cluster of showers and thunderstorms will move off the coast of Africa this weekend.
This new feature will move westward over the coming week and may stay in a moist environment.
The new feature has potential to develop into a full-blown tropical system as it approaches the Windward and Leeward islands provided westerly winds aloft ease up later next week.
