Coastal Flood Watch
* 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.
Coastal Flood Watch
* WHAT...1 1/2 to 2 1/2 ft, locally 3 ft, of inundation above ground level possible in vulnerable areas near the waterfront and shoreline. * WHERE...Southwest Suffolk and Southern Nassau Counties. * WHEN...From Sunday evening through late Sunday night. * COASTAL FLOOD IMPACTS...Widespread moderate flooding of vulnerable areas near the waterfront and shoreline possible. Expect 1 1/2 to 2 1/2 ft, locally 3 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 structures. * SHORELINE IMPACTS...Breaking surf of 4 to 8 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 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 structures.
Coastal Flood Watch
* WHAT...1 1/2 to 2 1/2 ft of inundation above ground level possible in vulnerable areas near the waterfront and shoreline. * WHERE...Northeast Suffolk and Southeast Suffolk Counties. * WHEN...From Sunday evening through 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 structures. * SHORELINE IMPACTS...Breaking surf of 4 to 8 ft along Gardiners Bay, particularly Orient Point, 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 structures.
Special Weather Statement
Most urban locations are just above freezing, but the more rural areas are right around the freezing mark. Due to residual moisture from recent precipitation, patchy black ice is expected on untreated roads and other surfaces in the more rural locations until 9 am when temperatures should warm above freezing everywhere. Be alert early this morning for wet spots that could be black ice. Slow down and travel with caution.

Air Quality Alert
The New York State Department of Environmental Conservation has issued an Air Quality Health Advisory for the following counties: New York, Bronx, Kings, Queens, Richmond, Westchester, Rockland until midnight EST Wednesday night. Air quality levels in outdoor air are predicted to be greater than an Air Quality Index value of 100 for the pollutant of Fine Particulates. The Air Quality Index, or AQI, was created as an easy way to correlate levels of different pollutants to one scale. The higher the AQI value, the greater the health concern. When pollution levels are elevated, the New York State Department of Health recommends that individuals consider limiting strenuous outdoor physical activity to reduce the risk of adverse health effects. People who may be especially sensitive to the effects of elevated levels of pollutants include the very young, and those with preexisting respiratory problems such as asthma or heart disease. Those with symptoms should consider consulting their personal physician. For additional information, please visit the New York State Department of Environmental Conservation website at, https://on.ny.gov/nyaqi, or call the Air Quality Hotline at 1 800 5 3 5, 1 3 4 5.

The Connecticut Department of Energy and Environmental Protection has issued an Air Quality Action Day for the following counties: Fairfield, New Haven until 11 PM EST this evening.
