...MINOR COASTAL FLOODING DURING HIGH TIDE THROUGH MID WEEK...

.Peak monthly high tides combined with water levels that are
running higher than predicted will lead to minor flooding in low-
lying coastal areas. Coastal flooding is possible through at
least Tuesday around the daily peak tide, which will be during
the afternoon hours. By Wednesday, tides are forecast to
decrease, though coastal flooding may still be possible for
select locations where water levels are running highest.
