A New York nor'easter can look completely different depending on where you live. The same storm can push salt water onto streets in Lower Manhattan and Long Island, drop heavy wet snow on trees in Rockland County, and bury a Catskills town under several feet of snow. A blog post can't tell you exactly what tonight's storm will do. The official forecast can. This guide points you to the right weather office, the right outage map for your address, and a backup power setup that makes sense for your home.
Storm Hitting New York Right Now? Where to Check First
Forecasts can change quickly, especially when snow bands and coastal flooding are involved. Your best storm update is the official source for your part of the state. New York is covered by several National Weather Service offices, so start with the one that serves your area.
What you need | Where to get it | Covers |
Warnings, snow and wind forecasts, coastal flood forecasts | NWS New York, NY (office in Upton, Long Island): weather.gov/okx | New York City, Long Island, and the Lower Hudson Valley |
Warnings and snow forecasts | NWS Albany: weather.gov/aly | Capital Region, Mid-Hudson Valley, Catskills, southern Adirondacks |
Warnings and snow forecasts | NWS Binghamton (office in Johnson City): weather.gov/bgm | Central New York and the Southern Tier |
Warnings and snow forecasts | NWS Buffalo (office in Cheektowaga): weather.gov/buf | Western and Central New York |
Statewide emergency alerts by text | NY Division of Homeland Security and Emergency Services (DHSES): text your county name to 333111 (borough names work in NYC), or enroll in NY-Alert at alert.ny.gov | Statewide |
New York City alerts | Notify NYC (NYC Emergency Management): text NOTIFYNYC to 692-692, use the free app, or call 311 | Five boroughs |
Power outages | Your electric company's outage map (see the utility table below) | By service territory |
If you aren't sure which NWS office covers your home, enter your ZIP code at weather.gov to find the forecast office serving your location. New York's Division of Homeland Security and Emergency Services also uses 333111 for county emergency alerts, while NY-Alert can send severe weather and transportation notices by phone, email, or text. For a downed power line, fire, or immediate danger, call 911 first, then the utility, and stay away from the line until crews make the area safe. Knowing the difference between a winter storm watch and warning can also help you judge how much time you have to prepare. Those forecast offices divide the state much like a nor'easter does: the storm flooding the coast isn't necessarily the one dumping feet of snow in the Catskills.
One Nor'easter, Three New Yorks: Coast, Hudson Valley, and Upstate
The National Weather Service defines a nor'easter as an East Coast storm with coastal winds that typically come from the northeast. These storms can bring heavy rain or snow, strong winds, rough seas, and coastal flooding. They can happen at any time of year but are most common and most severe from September through April. New York covers a huge range of terrain, from Atlantic beaches to mountain towns. That means your biggest problem may be rising water, falling trees, or the weight of snow on power lines.
Zone | Main nor'easter hazards | Documented example | Main electric companies |
New York City and Long Island | Coastal flooding, damaging wind, blizzard conditions | Feb 22 to 23, 2026: NWS preliminary data shows 31.0 inches at Central Islip, 19.7 inches at Central Park, and an 84 mph gust at Montauk Point | Con Edison, PSEG Long Island |
Hudson Valley | Heavy, wet snow and wind that bring trees onto lines; totals rise fast north and west of the city | Mar 7 to 8, 2018: 26.0 inches at Monroe and Sloatsburg while Central Park measured 3.2 inches | Orange and Rockland, Central Hudson, Con Edison (Westchester), NYSEG |
Upstate (Capital Region, Catskills, Central New York) | Deep snow, long travel shutdowns | Mar 2 to 3, 2018: 40.0 inches at two Schoharie County sites (NWS Albany) and 29.0 inches at Cazenovia (NWS Binghamton) | National Grid, NYSEG, RG&E |
New York City and Long Island: water and wind first
For New York Harbor, The Battery tide gauge is a key number to watch. The National Weather Service lists 9.4 feet MLLW as the major flooding level, while the December 1992 nor'easter reached 9.5 feet. A March 2010 coastal storm also brought a 75 mph gust at JFK Airport and 4.62 inches of rain at Central Park. Flooding can limit access while strong winds bring down trees and power lines, so check the coastal flood forecast for your area rather than relying only on snowfall totals.
Hudson Valley: the sharp snow gradient
Snowfall can change quickly across the Hudson Valley. During the January 2016 blizzard, New York City received more than 2 feet while parts of northern Orange County received only 1 to 2 inches. In March 2018, heavy, wet snow and strong winds brought down trees and power lines across the Lower Hudson Valley. A local forecast is more useful than a statewide snowfall headline.
Upstate: snow measured in feet
Farther north and west, a nor'easter can bring prolonged heavy snow. The March 2018 storms dropped 40 inches at two locations in Schoharie County and 29 inches in Cazenovia. Lake-effect snow is a separate hazard handled by NWS Buffalo. Along the coast, storm surge and snow together can leave flooded roads and snow-covered routes for utility crews at the same time. Whether an outage comes from flooding, wet snow, or falling trees, the result at home is the same: essential devices still need power.
Backup Power for a New York Nor'easter Outage
Wet snow and strong winds can bring trees and power lines down, as NWS documented during major storms in the Lower Hudson Valley and the New York City region. A battery power station produces no exhaust, so it can run indoors as designed while the storm keeps windows shut. For a short outage, a portable unit can cover essential devices; homeowners who want selected circuits backed up need an installed system.
Why indoor backup matters
The CPSC says never to use a portable generator inside a home or garage, even with doors and windows open. It recommends keeping a portable generator at least 20 feet from the house with the exhaust pointed away. That can be difficult during a blizzard and isn't practical for most New York City apartments.
How long can an EcoFlow DELTA 3 Max run?
For a simple planning estimate, use 2,048Wh × 0.85 ÷ load in watts. The 0.85 is a planning assumption for inverter and conversion losses, not an EcoFlow figure.
Total load you're running | Estimated runtime | Calculation |
100 W | About 17 hours | 2,048 × 0.85 ÷ 100 = 17.4 |
300 W | About 5.8 hours | 2,048 × 0.85 ÷ 300 = 5.8 |
1,000 W | About 1.7 hours | 2,048 × 0.85 ÷ 1,000 = 1.7 |
1,500 W (a typical plug-in space heater, such as a Lasko 1500W ceramic tower) | About 1.2 hours | 2,048 × 0.85 ÷ 1,500 = 1.16 |
The numbers show why a portable battery isn't practical for running an electric space heater for hours. A 1,500W heater can use most of its stored energy in about an hour. During a longer outage, use the battery for essentials such as phones, Wi-Fi, lights, a CPAP, or a refrigerator running in cycles. Dress in layers and keep to one closed-off room for warmth. Check your devices' wattage before deciding what to run. If the outage lasts more than a day, you'll also need to recharge. EcoFlow says the EcoFlow DELTA 3 Max can reach 0 to 80% in about 68 minutes from a wall outlet or generator, giving you a way to top it up where power is available.
For homeowners who need more coverage
A portable power station isn't the only option. The EcoFlow DELTA Pro Ultra X is an installed system for homeowners who want selected circuits backed up through Smart Home Panel 3. Whole-home backup requires Smart Home Panel 3 and installation by a licensed electrician, while the amount of the home it can support depends on the electrical loads. Electric heat, a well pump, or an electric range can increase the power requirement. If you've dealt with a multi-day outage, planning battery backup before the next winter storm can help you decide which devices or circuits need backup.
If you don't need whole-home backup, a portable power station can cover the essentials without a permanent installation. The EcoFlow DELTA 3 Max is a practical option for apartments, condos, rentals, or smaller outage setups where you need to keep a few key devices running.
How the two divide the job
The EcoFlow DELTA 3 Max is the plug-in option for renters, co-op and condo residents, and anyone who only needs to keep a few essential devices running for a day or so. The EcoFlow DELTA Pro Ultra X is designed for homeowners in places such as Westchester, Long Island, and the Hudson Valley who want selected home circuits backed up through Smart Home Panel 3 with installation by a licensed electrician. Stored power can cover the gap while the grid is down. Getting power restored starts with reporting the outage to the right company, and in New York, that depends on your address.
Who Is Your Electric Company? Outage Maps and Numbers by Region
New York doesn't have one electric company. Seven major utilities cover large parts of the state, and some counties have more than one service territory. Each company has its own outage map and reporting number, so check the name on your electric bill before the storm.
Electric company (exact name) | Where it serves | Outage map | Outage number, as the company labels it |
Consolidated Edison Company of New York, Inc. (Con Edison) | Manhattan, Brooklyn, Queens, the Bronx, Staten Island, and parts of Westchester County | "1-800-752-6633" (Con Edison's Report an Outage or Service Issue page); text OUT to 688-243 to start text reporting | |
Orange and Rockland Utilities, Inc. (O&R) | Orange, Rockland, and Sullivan counties | "Call Us at 1-877-434-4100" | |
PSEG Long Island (operates the Long Island Power Authority's grid under contract) | Nassau and Suffolk counties and the Rockaways in Queens | "Report an Outage: 1-800-490-0075, Call 24/7"; or text OUT to PSEGLI (773454) | |
National Grid (Niagara Mohawk Power Corporation d/b/a National Grid, upstate) | Much of upstate, including the Capital Region, Syracuse and Central New York, the North Country, and Buffalo and Western New York | "Report an Outage: 1-800-867-5222" | |
New York State Electric & Gas Corp. (NYSEG) | Binghamton and the Southern Tier, the Finger Lakes, and scattered areas statewide, including parts of Westchester, Putnam, and Dutchess | "If your electricity is out, report it ... by calling 800.572.1131" | |
Rochester Gas & Electric Corp. (RG&E) | Rochester area: Monroe County and parts of neighboring counties | "If your electricity is out, report it ... by calling 800.743.1701" | |
Central Hudson Gas & Electric Corp. | Mid-Hudson Valley: Dutchess, Ulster, and parts of Orange, Putnam, Greene, Columbia, Albany, and Sullivan | "PowerLine: (845) 452-2700 or 1-800-527-2714"; text REG to 236483 to enroll in outage texting |
PSEG Long Island operates the Long Island Power Authority's grid under contract, so use the full name PSEG Long Island, not "PSEG." New York also has municipal electric systems, so some residents need to use their village or city utility's contact page instead. Orange County deserves extra attention because customers there may have O&R, Central Hudson, or NYSEG service. Check your bill rather than guessing based on the county name.
Report the outage even if the map looks clear
Don't assume your neighbor's report covers your house. Report your own outage to the utility serving your address. Con Edison notes that outages can take up to 30 minutes to appear on its map, so a blank map doesn't necessarily mean the company hasn't received the report. Treat every downed line as energized and stay well away from it. If there's immediate danger, call 911 first. City residents can also benefit from tracking a Con Edison outage by address instead of assuming the entire neighborhood has the same status. Each utility has dealt with major winter storms before, and the historical record shows just how different those events can be.
The nor'easters New York still measures against
New York's biggest nor'easters span more than a century. The official records show coastal flooding, major snowfall, high winds, and storms that affected very different parts of the state. The figures below come from NWS, NOAA, or National Hurricane Center records.
Storm | What the record shows | Source |
Blizzard of March 1888 | 21.0 inches at Central Park (Mar 12 to 14) and 46.7 inches at Albany; NWS lists it among the classic nor'easters | NWS New York, NWS Albany |
December 1992 nor'easter | 9.5 feet MLLW at The Battery, above the 9.4-foot major flood level; the subject of an NWS disaster survey report | NWS New York; NWS Eastern Region (1994) |
March 12 to 15, 2010 | 75 mph gust at JFK, 70 mph at Bridgehampton; 4.62 inches of rain at Central Park, 5.37 inches at Levittown | NOAA Weather Prediction Center |
January 22 to 24, 2016 blizzard | 27.5 inches at Central Park, the largest storm total there since records began in 1869; 30.5 inches at JFK | NWS New York |
March 2018, four storms in three weeks | Mar 2 to 5: 78 mph gust at Bayville and 40.0 inches in Schoharie County. Mar 7 to 8: 26.0 inches at Monroe and Sloatsburg. Mar 13 to 15: about another foot at Albany. Mar 21: another heavy snow event for the metro area | NWS New York, Albany, Binghamton |
February 22 to 23, 2026 | Blizzard criteria met (preliminary) across the five boroughs, Nassau, Suffolk, and southern Westchester; 31.0 inches at Central Islip; 84 mph at Montauk Point | NWS New York |
Was Sandy a nor'easter?
No. The National Hurricane Center classified Sandy as a post-tropical cyclone when it made landfall near Brigantine, New Jersey, on October 29, 2012. Its 14.06-foot MLLW storm tide at The Battery remains the record there. The comparison is still useful because the December 1992 nor'easter reached 9.5 feet MLLW, making it the major nor'easter benchmark for New York Harbor. The February 2026 blizzard is the most recent storm on this list. It also shows why a forecast can change quickly from something to watch into a major travel and power problem.
What to Do Before, During, and After the Storm
A nor'easter usually gives you a few days to prepare, which is more warning than many weather emergencies provide. Use that time in order: check the forecast, get your power ready, protect the heat and food, then deal with cleanup once conditions improve.
Before the storm
Use the forecast window to handle the things that become harder once snow, wind, or flooding starts.
Sign up for alerts: Enroll in NY-Alert or text your county name to 333111. New York City residents can also use Notify NYC for local emergency updates.
Save your utility: Keep your electric company's outage number and outage map in your phone so you don't have to search for them during an outage.
Charge up: Fully charge phones, battery packs, and portable power stations while you still have reliable grid power.
Check coastal risks: If you're near the coast, move cars away from low-lying streets and check the NWS coastal flood forecast for your local area.
Refill prescriptions: Pick up essential medications before snow or flooding makes roads harder to travel.
During the storm
Once the storm arrives, focus on staying safe and keeping the heat inside.
Stay off the roads: Snow, flooding, fallen trees, and poor visibility can make even a short trip dangerous.
Hold in the heat: Close unused rooms, place towels along drafty doors, and cover windows if needed to help keep warm air inside.
Check the furnace vent: Make sure drifting snow hasn't blocked the vent outside, which can interfere with the furnace.
Use generators safely: Never run a generator or grill inside your home or attached garage. CPSC recommends keeping a portable generator at least 20 feet from the house.
Check CO alarms: Keep working carbon monoxide alarms on every level and outside sleeping areas, especially if you're using fuel-burning equipment outdoors.
Keep food cold
A refrigerator can keep food safe for about 4 hours without power if you keep the door closed. A full freezer can hold food for about 48 hours, while a half-full freezer can last about 24 hours. Avoid opening the doors just to check the temperature. If the outage lasts longer, use a food thermometer to check whether refrigerated food is still safe before eating it.
After the storm
Wait until conditions are safe, then work through the outage and any damage around your property.
Report your outage: Contact your utility even if a neighbor has already reported theirs. Your report helps the utility track the affected area.
Stay away from lines: Treat every downed power line as live and keep clear of anything touching it.
Check for storm damage: After a major event, NY DHSES may provide a damage self-reporting tool to help document impacts across the state.
Use your battery carefully: Ration stored power for essential devices if restoration is taking longer than expected.
Small habits like keeping one room warm and rationing battery power can make a long winter outage much easier to manage.
Conclusion
A New York nor'easter can mean flooding and high winds on the coast, heavy wet snow in the Hudson Valley, or several feet of snow upstate. Your local NWS office tells you what the storm is doing, while your electric company's outage map tells you what is happening to the grid at your address. Bookmark both before the next storm. For short outages in an apartment or condo, the EcoFlow DELTA 3 Max can keep essential plug-in devices running. Homeowners who want selected circuits backed up can look at the EcoFlow DELTA Pro Ultra X with Smart Home Panel 3 and a licensed electrician.
