沿海洪水警报

* WHAT...For the Coastal Flood Warning, one to two feet and
locally up to 2 1/2 feet of inundation above ground level in
vulnerable areas near the waterfront and shoreline. For the High
Surf Advisory, large breaking waves of 7 to 14 feet in the surf
zone. For the High Rip Current Risk, dangerous rip currents.

* WHERE...Southwest Suffolk and Southern Nassau Counties.

* WHEN...For the Coastal Flood Warning, until 6 PM EDT Sunday.
For the High Surf Advisory, until 8 PM EDT Sunday. For the
High Rip Current Risk, through Sunday evening.

* COASTAL FLOOD IMPACTS...Widespread moderate to major flooding of
vulnerable areas near the waterfront and shoreline. There is an
elevated threat to low lying properties. Flooding could extend
inland from the waterfront and shoreline into areas that
typically don't experience coastal flooding. Flooding will
likely be exacerbated along north facing shorelines from wave
action, particularly for the barrier island from Atlantic Beach,
Long Beach to Jones Beach. This will result in numerous road
closures and cause widespread flooding of low lying property
including parking lots, parks, lawns, and homes and businesses
with basements near the waterfront. Vehicles parked in
vulnerable areas near the waterfront will likely become flooded.
Flooding in the most vulnerable areas may not totally recede
during the times of low tide.

* SHOREFRONT AND BEACH IMPACTS...Breaking waves of 6 to 10 feet
along with elevated water levels will result in widespread dune
erosion and beach flooding. Localized overwashes are possible
where dune structures are compromised, resulting in some
flooding of roadways and vulnerable structures behind protective
dunes. Dangerous swimming and surfing conditions and localized
beach erosion. Life threatening rip currents are likely for all
people entering the surf zone. Anyone visiting the beaches
should stay out of the surf. Rip currents can sweep even the
best swimmers away from shore into deeper water.
