...HIGH SURF ADVISORY REMAINS IN EFFECT FOR THE SOUTH FACING SHORES OF ALL HAWAIIAN ISLANDS THROUGH MONDAY... ...COASTAL FLOOD STATEMENT REMAINS IN EFFECT FOR ALL SHORES OF ALL HAWAIIAN ISLANDS THROUGH TONIGHT... A large south swell will produce high end advisory level surf along all south facing shores. Surf heights will begin to gradually decline today and tonight. The High Surf Advisory was extended in time through Monday. Peak afternoon high tides, combined with elevated water levels running about a half a foot higher than normal, will lead to minor flooding along most shorelines and low lying coastal areas today. Water levels should fall below thresholds by Monday. Corrected the surf heights in the WHAT section to show decreasing High Surf Advisory trends through Monday.
