CONTINUE TO WEAKEN WHILE MOVING WESTWARD OVER THE NEXT 48 
HOURS...SHIFTING W OF THE FORECAST AREA BY WED NIGHT.

CONFUSED SEAS IN EXCESS OF 8 FT WILL CONTINUE TO IMPACT THE 
MAJORITY OF THE WATERS W OF 100W THROUGH THE NEXT 48 HOURS AS A 
RESULT OF KARINA...LOWELL...AND MARIE. MEANWHILE...THE WATERS E 
OF 100W WILL BE COMPARATIVELY MORE TRANQUIL WITH GENTLE TO
