When nor'easters hit bringing disruptive snowfall, there are often enormous differences in the amount of snow from one place to the next. Today's nor'easter is no exception.

Freehold in New Jersey has been buried beneath 22 inches (55cm) of snow, whereas 90 miles (145km) west in Breinigsville, Pennsylvania, there has been a more manageable 10cm of snow so far.

According to the website poweroutage.us, there are currently over 400,000 people without power in blizzard affected states. The snow continues to fall heavily so further, increasingly widespread disruption to power and transport is inevitable.

Reporting from London

I’m flying from London to Washington DC today, and was mentally preparing myself for the frustration of major delays to my trip, given the huge snowstorm hitting the US.

But I’ve just boarded my flight, and as my fellow passengers and I find our seats and load up our carry-on items, the pilot is announcing that we seem to be mostly on schedule and should land in DC on time. The city wasn’t hit as hard by the storm as forecasters feared, he says.

A rare pleasant surprise while travelling - I’ll take it!

We might encounter some turbulence as we fly over the US, the pilot says. I’ll keep my seatbelt fastened and hope the weather doesn’t worsen while I’m in the air.

I’ve been for a walk around my neighbourhood in Brooklyn this morning to see how much snow we got, and it’s a lot.

It’s shin-deep unless you are walking on the snow-ploughed streets, which a handful of people were doing because there’s a travel ban in place and the only vehicles out there seem to be ploughs and police SUVs.

I had a quick chat with a dog walker who tells me her pup Bandit is having the time of his life. Her, not so much.

People are waking up to several inches of snow, as a major snow storm batters the northeastern states of the US.

• But there's more to come: Some areas of the north-east could see around 2ft (60cm) of snow and wind gusts of up to 70mph before the storm moves towards the Maritimes, along the Atlantic coast in eastern Canada. For the latest forecast where you are, head to BBC Weather
• States of emergency: New York, Delaware, Massachusetts, New Jersey and Connecticut, Rhode Island and Pennsylvania have all declared states of emergency, with New York City Mayor Zohran Mamdani among those urging residents to stay at home
• Quiet on the roads: A travel ban is currently in place in NYC - to last until midday on Monday (17:00 GMT) - meaning only essential vehicles are allowed on roads and bridges throughout the five boroughs
• Flights up in the air: As of 07:00 ET (12:00 GMT), more than 5,500 flights into, out of, or within the US have been cancelled today - New York airports John F Kennedy International and LaGuardia are among the worst affected
• Schools are out: Schools are closed across New York City, with 13 school buildings being repurposed as "warming centres" for the duration of the blizzard. Many schools are also closed in Massachusetts, Rhode Island, Pennsylvania, Delaware, Connecticut and New Jersey. Public schools in Washington remain open, but have opened two hours late
• And so is power: A live outage tracker is reporting hundreds of thousands without power, including 122,000 in New Jersey, 146,000 in Massachusetts and 71,000 in Delaware

Power outages are affecting hundreds of thousands of people across the north-east US right now, according to the live tracker Power Outage.

This includes 122,000 customers in New Jersey, 99,000 in Massachusetts and 71,000 in Delaware, as of 07:00 EST (12:00 GMT).

One New Jersey-based electrics company, Atlantic City Electric, says it is "prepared to respond to any issues".

Delaware Electric Coop says it's "facing an absolute mess" due to "countless trees, powerlines and utility poles" being struck down by the snow.

"We'll be calling on our friends from neighbouring mid-Atlantic cooperatives to help us get the lights back - a process we think will take days," it says.

Video from New York City shows the Empire State Building engulfed by a snow storm during the early hours of Monday.

It is now 07:00 EST (12:00 GMT) and east coasters are waking up to heavy snow.

New photos from a transport station in Manhasset, New York, show a snow-blanketed train platform and a vehicle working to clear the road outside.

More than 5,000 flights have already been cancelled so far today, power outages are widespread across the north east, and New York City has shut down all streets and bridges to non-essential traffic.

With many parts of the north-eastern US waking up to a blanket of snow on Monday, here is the latest from BBC Weather on what we could see through the rest of the day.

This winter storm is being called a "nor'easter" - BBC Weather presenter Chris Fawkes explains what that means.

Nor'easters are strong areas of low pressure that deepen off the east coast of the US.

They're really common and happen every year, and don't necessarily have to bring snow - some of them bring heavy rain, strong winds and coastal flooding.

They develop due to strong temperature contrasts as cold polar air collides with much warmer maritime air heated by the Gulf Stream.

These huge contrasts create a very powerful jet stream that can rapidly deepen areas of low pressure into intense storms.

As the low pressures strengthen out to sea, the winds affecting eastern US states and Atlantic Canada tend to blow from the northeast which is where the nor'easters get their name from.

Areas of New York saw nearly 15 inches of snowfall overnight in some areas, the National Weather Service says.

In Long Island, snow fell at a rate of three inches per hour for parts of the night, according to an NWS post on X, with "heavy snow still falling".

It's still the very early morning in the US, and we will bring you more updates as parts of the country start to wake up.

As we have been reporting, more than 5,000 flights within, into or out of the US are cancelled today, and almost 600 more are delayed.

According to FlightAware, the two airports with the most cancellations - John F Kennedy and LaGuardia - are based in New York.

As of 11:00 GMT (06:00 ET), here are the US airports facing the most cancellations today.

These figures take into account flights setting off and arriving to the airports, so one flight will be impacting two locations.

• John F Kennedy International: 1,086 cancellations
• LaGuardia: 1,025 cancellations
• Boston Logan International: 968 cancellations
• Newark Liberty International: 861 cancellations
• Philadelphia International: 602 cancellations

JetBlue, an American low-cost airline that has cancelled 776 flights, says customers can expect "significant disruptions and cancellations" until 24 February.

As we've already reported, flights from the UK and Ireland to New York and Boston have been cancelled on Monday.

In the US, the National Weather Service (NWS) is responsible for issuing forecasts, watches and warnings for a variety of weather and water hazards.

It forms part of the National Oceanic and Atmospheric Administration (NOAA), which is a federal government agency.

The NWS issues warnings when "hazardous weather poses an immediate threat to life or property".

As a reminder, tens of millions in the US are facing winter storm warnings or the more extreme blizzard warnings.

A winter storm warning is issued when the threat is "predominantly snow or a mix of snow and sleet", the NWS says, while a blizzard warning involves "sustained or frequent gusts to 35mph (56km/h) or greater and considerable falling and/or blowing snow", with conditions lasting for at least three hours.

A powerful blizzard is battering the northeastern US states with heavy snow and very strong winds combining to bring widespread transport disruption and some powercuts.

There's already been 18 inches (45cm) of snow recorded in some eastern parts of Pennsylvania with the heaviest snow moving across Delaware, Pennsylvania, New Jersey, New York, Connecticut, Rhode Island and Massachusetts through Monday.

Some areas could see around 2ft (60cm) of snow before the storm moves away during Monday night.

There will be some huge drifts of snow as winds gust up to 70mph, strong enough to bring down trees and powerlines.

The storm will then affect the Maritimes in Canada on Monday night and into Tuesday.

Another round of snow will move across the northeast of the US on Wednesday as an 'Alberta clipper' area of low pressure races through.

People up and down the north-east of the US will be waking up to snow this morning as an intense winter storm continues to hit, with tens of millions under blizzard and winter storm warnings.

While snow on the beach in Atlantic City and snow blanketed roads in New York make a pretty picture, it's already causing widespread disruption with power cuts and flight cancellations.

It's not just flights in the US that are affected by the storm - lots of flights in the UK heading across the Atlantic have been cancelled or delayed.

A number of departures from Heathrow to cities including Boston, New York and Philadelphia are cancelled through Monday morning and afternoon.

Flights from Manchester and Edinburgh to New York airports were also showing as cancelled on Monday morning.

Some flights between the US and Dublin Airport have also been cancelled today due to "adverse weather", the airport says, advising people to check with their airline for the latest updates.

Schools in New York City will be closed on Monday, with no remote learning for pupils, as the city faces its first blizzard warning in nearly a decade.

New York City's public schools authorities say that 13 school buildings will be open to be used as "warming centres".

Many schools in Massachusetts, Rhode Island, Pennsylvania, Delaware, Connecticut and New Jersey are also closed on Monday, although state-wide closures are not in place.

Meanwhile in Washington DC, mayor Muriel Bowser says public schools will open "with a two-hour delay".

Blizzards are winter storms where heavy snowfall or blowing snow combines with winds over 35mph (56km/h) to create visibility of less than a quarter of a mile (402m) for three hours or more, according to the National Weather Service.

In the US, blizzards are most common in the Great Plains and Midwest, especially in an area known as "Blizzard Alley", which includes parts of North Dakota, South Dakota, Minnesota, Iowa, Nebraska, southeastern Wyoming, and eastern Colorado.

That's because these areas are relatively flat with few trees or obstructions to curb wind and blowing snow.

The last time New York City faced a blizzard warning was nearly a decade ago in March 2017. In Philadelphia, the last one was issued in January 2016. The last time the entire state of New Jersey was under a blizzard warning was in 1996.

Sunday's storm comes on the heels of another major snowstorm, which struck the region in January and blanketed New York City with almost a foot of snow. That storm, however, did not have the associated winds to be considered a blizzard.

People up and down the north-east coast were pictured preparing for the storm on Sunday, with some getting in a final dog walk before conditions worsened and others stocking up on rock salt - and even a sled.

As of midnight local time (05:00 GMT) on Monday, much of the north-east had already been blanketed in several inches of snow, with 10 inches (25cm) reported in Manorville, New York and Howell, New Jersey, according to the US National Weather Service (NWS).

We will bring you all the latest images and video throughout Monday.
