* WHAT...For the Coastal Flood Warning, 2 to 4 feet of
inundation above ground level expected in low- lying areas
near shorelines and tidal waterways. For the High Surf
Advisory, large breaking waves of 9 to 14 feet in the surf
zone. For the Beach Hazards Statement, dangerous rip currents,
large breaking waves, and strong longshore currents in the
surf zone.

* WHEN...For the Coastal Flood Warning, until 5 PM EDT Tuesday.
For the Beach Hazards Statement, from Sunday morning through
Sunday evening.

* IMPACTS...2 to 4 feet of inundation above ground level is
expected in some areas near shorelines and tidal waterways
resulting in an elevated threat of property damage. Flooding
will extend inland from the waterfront threatening some homes
and businesses. Numerous road closures and flooding of
vehicles will be possible. Vulnerable portions of NC-12 may be
inundated, especially around high tide. There is a possibility
of being stranded on Hatteras Island for multiple days. This
could be life threatening if you have an emergency. Dangerous
swimming and surfing conditions and localized beach erosion.
Rip currents can sweep even the best swimmers away from shore
into deeper water. Dangerous shore break can throw a swimmer
or surfer head first into the bottom causing neck and back
injuries. Strong longshore currents will create dangerous
swimming conditions.

* ADDITIONAL DETAILS...This has the potential to be a long
duration event bringing more significant ocean overwash impacts
to vulnerable oceanside areas through multiple high tide cycles
into the work week. Minor soundside water level rises will also
be possible.
