Alertes en vigueurPatchogue, 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.

Multiple Bands of Heavy Snow to Impact the Area Overnight Bands of heavy snow will move across the area through the overnight as low pressure rapidly intensifies to the south. Some of these bands will produce 2 to 3 inches per hour rates. However, in between bands, snowfall rates may drop off to about an inch per hour. Farther to the west, across western portions of the Lower Hudson Valley and interior portions of northeast New Jersey there will be a sharp back edge to the heavy snow and some uncertainty as to how far these bands get. This could impact snowfall totals across this area. Additionally, winds will become a factor as the night progresses. Blizzard conditions are expected and will make travel treacherous and potentially life-threatening.
