on either side of high tide.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
A Coastal Flood Advisory is issued for minor coastal flooding of
the most vulnerable shore roads and/or basements due to the
height of storm tide or wave splashover. The majority of roads
remain passable with only isolated closures. There is no
significant threat to life...and impact on property is minimal.

Time of high total tides are approximate to the nearest hour.
Category thresholds are based on still water levels. Impacts
