Coastal Flood Advisory issued February 22 at 3:22PM EST until February 23 at 6:00PM EST by NWS Upton NY
* WHAT...For the Coastal Flood Warning, 1 1/2 to 2 1/2 ft, locally
3 ft, of inundation above ground level expected in vulnerable
areas near the waterfront and shoreline. For the Coastal Flood
Advisory, up to 1 1/2 ft of inundation above ground level
expected in vulnerable areas near the waterfront and shoreline.
* WHERE...Southwest Suffolk and Southern Nassau Counties.
* WHEN...For the Coastal Flood Warning, from 10 PM this evening
to 4 AM EST Monday. For the Coastal Flood Advisory, from 11 AM
to 6 PM EST Monday.
* COASTAL FLOOD IMPACTS...Widespread moderate to localized major
flooding of vulnerable areas near the waterfront and shoreline
likely. Expect 1 1/2 to 2 1/2 ft, locally 3 ft of inundation
above ground level possible in low lying, vulnerable areas. This
will 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 structures.
* SHORELINE IMPACTS...Breaking surf of 5 to 10 ft along the ocean
front will cause widespread beach flooding and erosion during
the time of high tide. Areas of dune erosion are likely, with
localized washovers possible where dunes are compromised.
* ADDITIONAL DETAILS...This water level forecast has been leaned
towards a high end scenario, providing a margin of safety. It is
highly dependent on timing of windshift from northeast to north
storm force winds with respect to the time of high tide. If
shift to northerly winds occurs earlier than time of high tide,
water levels will fall to the low end or even below the
forecast range. Ice cover in the bays and harbors could
exacerbate flooding and cause damage to north to northeast
facing shoreline structures. Additional minor to locally
moderate coastal flooding is likely with the Monday afternoon
high tide.
Take the necessary actions to protect flood-prone property. If
travel is required, do not drive around barricades or through
water of unknown depth.
