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. .OVERNIGHT...S of 27N, SW to W winds 5 to 10 kt.
