region. Seas are forecast to be slight across the Gulf Mon
through Wed.

.SYNOPSIS...Major Hurricane Erin is near 19.7N 62.8W at 11 AM
EDT, and is moving west at 15 kt. Maximum sustained winds are
135 kt with gusts to 165 kt, and the minimum central pressure is
923 mb. Erin will move to near 20.1N 64.7W this evening with

is forecast to change little in intensity as it moves to near
30.6N 70.9W early on Wed, then  continue to weaken later on Wed
as it lifts well north of 31N. Swells generated by Erin will
affect portions of the northern Leeward Islands, the Virgin
Islands, Puerto Rico, Hispaniola, and the Turks and Caicos
Islands through the weekend. These swells  will spread to the
Bahamas, Bermuda, and the east coast of the  United States early
next week. Otherwise, high pressure will  ridging will begin to
