Within 200 nm east of the coast of Florida



.SYNOPSIS...Hurricane Erin is near 24.8N 72.0W at 5 AM EDT, and 

is moving northwest at 6 kt. Maximum sustained winds are 100 kt 

with gusts to 120 kt, and the minimum central pressure is

955 mb. Erin will move to 26.1N 72.7W this afternoon, 28.1N 73.5W

Wed morning, 30.3N 74.0W Wed afternoon, 32.6N 73.4W Thu morning, 

34.6N 71.4W Thu afternoon, and 36.5N 68.4W Fri morning. Erin will 

change little in intensity as it moves near 39.5N 61.0W early Sat.

Swells generated by Erin will affect the Bahamas, Bermuda, the 

east coast of the United States, and Atlantic Canada during the 

next several days. These rough ocean conditions are expected to 

cause life-threatening surf and rip currents. Otherwise, a tropical

wave located over the central tropical Atlantic continues to 

produce a broad area of disorganized showers and thunderstorms. 

Environmental conditions appear conducive for gradual development 

of this system, and a tropical depression could form toward the 

end of the week or weekend. This system should move westward to 

west-northwestward at about 20 kt across the central tropical 

Atlantic and approach the vicinity of the Leeward Islands on 

Friday.
