ADVISORY REMAINS IN EFFECT THROUGH THIS AFTERNOON FOR NORTH FACING
SHORES OF KAUAI, OAHU, MOLOKAI AND MAUI. SURF WILL GRADUALLY
DECLINE THROUGH FRIDAY AS THE SWELL SHIFTS OUT OF THE NORTH AND

WELL BELOW AVERAGE DUE TO THE LACK OF TRADES LOCALLY AND UPSTREAM. THE
EXCEPTION WILL BE FOR EAST FACING SHORES EXPOSED TO NORTH- NORTHEAST
