.A medium to large north-northwest medium period swell will
continue to move across the Hawaiian Islands through Thursday
increasing surf heights to near advisory thresholds along exposed

running higher than predicted will lead to minor flooding along
the shoreline and in low-lying coastal areas. Coastal flooding is
possible around the daily peak tide, which will be during the
early morning hours.
