Coastal Flood Watch  COASTAL FLOOD WATCH   Coastal Flood Watch
NW SUFFOLK

Areas Affected:
Bronx - Northwest Suffolk - Northern Queens - Northern Nassau
Effective: Fri, 2/20 4:27pm Updated: Sat, 2/21 12:57pm Urgency: Future
Expires: Sat, 2/21 5:00pm Severity:  Moderate  Certainty: Possible

 
Details:
* WHAT...1 1/2 to 2 1/2 ft of inundation above ground level
possible in vulnerable areas near the waterfront and shoreline.

* WHERE...Bronx, Northwest Suffolk, Northern Queens and Northern
Nassau Counties.

* WHEN...Late Sunday night.

* COASTAL FLOOD IMPACTS...Widespread moderate flooding of
vulnerable areas near the waterfront and shoreline possible. 1
1/2 to 2 1/2 ft of inundation above ground level possible in low
lying, vulnerable areas. This would result in numerous road
closures and cause widespread flooding of low lying property
including parking lots, parks, lawns and homes/businesses with
basements near the waterfront. Vehicles parked in vulnerable
areas near the waterfront will likely become flooded. Flooding
will also extend inland from the waterfront along tidal rivers
and bays. Ice cover in the bays and harbors could
exacerbate flooding and cause damage to northeast to east facing
shoreline structure.

* SHORELINE IMPACTS...Breaking surf of 3 to 5 ft along north and
east facing shorelines will cause beach flooding and dune
erosion during the time of high tide. This may also exacerbate
splashover flooding of shorelines roads and properties behind
protective dunes, structures and seawalls. Minor damage to
shoreline structures possible.

* ADDITIONAL DETAILS...This water level forecast will be highly
dependent on timing of windshift from east northeast to north
gales with respect to the time of high tide, and will be refined
over the next 24 hours. Ice cover in the bays and harbors could
exacerbate flooding and cause damage to northeast to east facing
shoreline structure.

Information:
If travel is required, allow extra time as some roads may be
closed. Do not drive around barricades or through water of
unknown depth. Take the necessary actions to protect flood-prone
property.
