Within 200 nm east of the coast of Florida

.SYNOPSIS...Hurricane Erin is centered north of the area near
32.8N 73.1W, or about 420 nm west of Bermuda at 11 PM EDT, and is
moving north at 14 kt. Maximum sustained winds are 95 kt with
gusts to 115 kt, and the minimum central pressure is 942 mb. Erin
will continue to pull NNE far away from the region through the end
of the week while slowly weakening. Long period northerly swells
generated by Erin will affect just about the entire forecast
domain through the next few days. In the wake of Erin, central
Atlantic high pressure will build WSW toward the central Bahamas
and the Straits of Florida through the period. Looking ahead, a
tropical wave located several hundred miles east of the Leeward
Islands is producing a broad area of disorganized showers and
thunderstorms. Environmental conditions appear conducive for
gradual development of this system, and a tropical depression is
likely to form by this weekend while it moves near or to the north
of the northern Leeward Islands.
