Coastal Flood Watch issued February 20 at 4:27PM EST until February 23 at 5:00AM EST by NWS Upton NY
Effective: Fri February 20, 2026, 4:27 PM
Expires: Sat February 21, 2026, 5:00 PM
* WHAT...1 1/2 to 2 1/2 ft of inundation above ground level possible in vulnerable areas near the waterfront and shoreline. * WHERE...In Connecticut, Southern Fairfield and Southern New Haven Counties. In New York, Southern Westchester County. * 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.
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.
Blizzard Warning issued February 21 at 1:02PM EST until February 23 at 6:00PM EST by NWS Upton NY
Effective: Sat February 21, 2026, 1:02 PM
Expires: Sun February 22, 2026, 3:00 AM
* WHAT...Blizzard conditions expected. Total snow accumulations between 11 and 15 inches. Winds gusting as high as 45 mph. * WHERE...Portions of southern Connecticut and southeast New York. * WHEN...From 1 PM Sunday to 6 PM EST Monday. * IMPACTS...Visibilities may drop below 1/4 mile due to falling and blowing snow. Whiteout conditions are expected and will make travel treacherous and potentially life-threatening. The strong winds and weight of snow on tree limbs may down power lines and could cause sporadic power outages. Travel could be very difficult to impossible. Areas of blowing snow could significantly reduce visibility. The hazardous conditions could impact the Monday morning and evening commutes.
Travel should be restricted to emergencies only. If you must travel, have a winter survival kit with you. If you get stranded, stay with your vehicle. Check local Department of Transportation information services for the latest road conditions. A Blizzard Warning means severe winter weather conditions are expected or occurring. Falling and blowing snow with strong winds are likely. This will lead to whiteout conditions, making travel extremely dangerous. Do not travel. If you must travel, have a winter survival kit with you. If you get stranded, stay in your vehicle.

* WHAT...Blizzard conditions expected. Total snow accumulations between 15 and 20 inches, highest amounts across Long Island. Winds gusting as high as 55 mph with isolated gusts up to 60 mph. Gusts on the east end of Long Island could reach 65 mph. * WHERE...Portions of southern Connecticut and southeast New York. * WHEN...From 1 PM Sunday to 6 PM EST Monday. * IMPACTS...Visibilities may drop below 1/4 mile due to falling and blowing snow. Whiteout conditions are expected and will make travel treacherous and potentially life-threatening. The strong winds and weight of snow on tree limbs may down power lines and could cause sporadic power outages. Travel could be very difficult to impossible. Areas of blowing snow could significantly reduce visibility. The hazardous conditions will impact the Monday morning and evening commutes. * ADDITIONAL DETAILS...Strongest winds are expected Sunday evening through Monday afternoon.

* 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.
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.
