The axis of a westward moving tropical wave is located just under 300 miles east of the Lesser Antilles. Scattered moderate convection is associated with the wave.
Scattered showers and thunderstorms are presently noted just east of Guadeloupe, Dominica, Martinique, St Lucia, Barbados, St.Vincent and The Grenadines moving westward.
A non-tropical low pressure system is expected to develop along a frontal boundary over the central Atlantic Ocean between Bermuda and the Azores by tonight. Gradual development of this system is possible while it moves slowly westward, and a tropical or subtropical depression could form on Tuesday or Wednesday before upper-level winds become unfavorable.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...50 percent.
Another non-tropical low pressure system is forecast to develop over the western North Atlantic between Bermuda and the east coast of the United States in a few days. The low could acquire some subtropical characteristics later in the week while it meanders off the east coast of the United States.
* Formation chance through 48 hours...low...near 0 percent.
