Blizzard Warning issued February 23 at 1:52AM EST until February 23 at 6:00PM EST by NWS Upton NY

Effective: Mon February 23, 2026, 1:52 AM
Expires: Mon February 23, 2026, 2:00 PM

* WHAT...Blizzard conditions. Additional snow accumulations between 9 and 14 inches. Winds gusting as high as 55 mph. * WHERE...Portions of southern Connecticut and southeast New York. * WHEN...Until 6 PM EST this evening. * 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. Strong winds could cause tree damage.

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.

Coastal Flood Advisory issued February 22 at 3:22PM EST until February 23 at 6:00PM EST by NWS Upton NY

Effective: Sun February 22, 2026, 3:22 PM
Expires: Mon February 23, 2026, 5:00 PM

* 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.

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 Gardiners Bay, particularly Orient Point and north shore of the south fork, 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 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.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
