For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
1. A non-tropical low pressure system is expected to develop along a
frontal boundary over the central Atlantic Ocean between Bermuda and
the Azores during the next day or two. Gradual development of this
system is possible while it moves slowly westward, and a tropical or
subtropical depression could form by the middle of the week before
upper-level winds become unfavorable.
Formation chance through 48 hours...low...20 percent.
Formation chance through 5 days...medium...50 percent.
2. 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 by the middle of the week. 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.
Formation chance through 5 days...low...30 percent.
