.Synopsis for Puerto Rico and the U.S. Virgin Islands Waters...
Lingering moisture will support showers and isolated thunderstorms
across the regional waters today. Marine conditions will deteriorate
toward the end of the week as easterly winds strengthen and seas
build, resulting in hazardous conditions for small craft. Conditions
could deteriorate further late this weekend into early next week
depending on the development and track of AL92.
