Coastal Flood Advisory


Coastal Hazard Message
National Weather Service New York NY
608 PM EDT Thu Sep 5 2019

...MINOR TO LOCALLY MODERATE COASTAL IMPACTS FRIDAY INTO SATURDAY...

Southwestern Suffolk-Southeastern Suffolk-Southern Queens-
Southern Nassau-
608 PM EDT Thu Sep 5 2019

...COASTAL FLOOD ADVISORY IN EFFECT FROM 1 PM FRIDAY TO 9 PM EDT
SATURDAY...
...HIGH SURF ADVISORY REMAINS IN EFFECT FROM 2 PM FRIDAY TO 9 PM
EDT SATURDAY...

The National Weather Service in New York NY has issued a Coastal
Flood Advisory, which is in effect from 1 PM Friday to 9 PM EDT
Saturday.

* LOCATIONS...Vulnerable coastal locales along Southwestern
  Suffolk, Southeastern Suffolk, Southern Queens and Southern
  Nassau, including the Atlanic ocean beachfront and twin forks of
  Long Island.

* TIMING...For the High Surf Advisory, from 2 PM Friday to 9 PM
  EDT Saturday. For the High Rip Current Risk, through Saturday
  evening. For the Coastal Flood Advisory, minor to locally
  moderate during the times of high tide from 1 PM Friday to 9 PM
  EDT Saturday.

* COASTAL FLOOD IMPACTS...Shallow flooding is expected in the
  most vulnerable locations near the waterfront and shoreline.
  Expect around 1 to 2 feet of inundation above ground level in
  low lying, vulnerable areas. Some roads and low lying property
  including parking lots, parks, lawns and homes/businesses with
  basements near the waterfront will experience shallow flooding.

* SHORELINE IMPACTS FRIDAY THROUGH SATURDAY...High surf will
  develop Friday Afternoon into Friday Evening, peaking at 6 to 10
  kt for the ocean beaches of NYC and Western Long Island, and 8
  to 12 feet across Eastern Long Island beaches Friday Night into
  Saturday Morning, before gradually subsiding Saturday afternoon.
  These large breaking waves will result in significant beach
  flooding and erosion. Areas of erosion to dune structures and
  localized washovers are also possible during the times of high
  tide, resulting in some flooding of roadways and vulnerable
  structures behind low-lying protective dunes. Finally, very
  dangerous rip currents are expected during this time, posing a
  danger to anyone who enters the surf.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A High Surf Advisory means that high surf will affect beaches in
the advisory area, producing rip currents and localized beach
erosion.

A Coastal Flood Advisory indicates that onshore winds and tides
will combine to generate flooding of low areas along the shore.

Rip currents are powerful channels of water flowing quickly away
from shore, which occur most often at low spots or breaks in
sandbars and near structures such as groins, jetties, and piers.
Talk to lifeguards and beach officials to learn about any surf
hazards and heed their advice. Pay attention to flags and posted
signs and swim in life guarded areas.

Swim near a lifeguard. If caught in a rip current, relax and
float, and do not swim against the current.  If able, swim in a
direction following the shoreline. If unable to escape, face the
shore and call or wave for help.
