“In my 18 years being the emergency management director this is the most [snow] that we’ve seen," Appleby said.
[Updated at 11:55 a.m. ET] More detail has emerged about stranded motorists and traffic accidents on New York's Long Island.
Crews in Suffolk County helped remove motorists stranded along a county road and took them to a local town hall where they were given meals, a county official told CNN's Kirsten Swanson.
About 60 cars were stuck. Forty people were recovered but some wanted to stay in their cars as the blizzard.
On Long Island's Nassau County, more than 100 accidents occurred, a county official told CNN.
Long Island has been hammered by the storm. The town of Islip has received more than 27 inches.

[Updated at 10:45 a.m. ET] Here's a dispatch and a picture from CNN's Brandon Miller, who is checking out the snowfall in Boston, which has received nearly 2 feet of snow:
Now that there is daylight, you can really get a feel for just how much snow has fallen in the last 24 hours. Where there was grass and bare ground yesterday morning, now there is several feet of drifted snow.
In some places, the snow appears only about 10 inches deep, but that's only because the wind has blown the fluffy light snow into a waist-high deep drift a few paces away.
At downtown Boston's iconic Quincy Market (pictured below), where a couple feet of snow has fallen, a Saturday morning would normally have loads of people walking through. This morning, however, it has only a few plow operators.
[Updated at 10:16 a.m. ET] Remember the news a few days ago that the Postal Service will end Saturday letter delivery in August? Today, New England and parts of New York are getting a preview, CNN's Pauline Kim reports.
Because of the weather, post offices are closed and no deliveries will be made today in Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island and Vermont, and in the Hudson Valley area north of New York City, Postal Service representative Christine Dugas said.
"Conditions continue to be evaluated with public services through local post offices expected to resume on Monday," the Postal Service said Saturday morning.
[Updated at 9:55 a.m. ET] A sister of a New York man who police say died in a snow-related accident Friday says that he was walking his dog when a vehicle struck him.
Muril Hancock, 74, was struck by a car in Poughkeepsie on Friday afternoon, police say. The driver, an 18-year-old woman, lost control of the vehicle in the falling snow, and Hancock died in a hospital from his injuries, according to police.
Hancock's death is the one fatality CNN knows to have been linked to the snowfall so far.
His sister, Sharon Hancock of Manchester, New Hampshire, told CNN Saturday that her brother loved to fish and hunt, play the guitar and listen to jazz.
"He bought me my first car, he took me to college, and he called me every Saturday (or) Sunday faithfully by 7 o'clock," Sharon Hancock said. "He was the best brother."

Connecticut has "really (gotten) the sweet spot of this storm" so far, CNN meteorologist Alexandra Steele said.
[Updated at 9:02 a.m. ET] New York City appears to have fared a little better than central and eastern Long Island. The city generally received less snow (about 1 foot) than Long Island, Mayor Michael Bloomberg told reporters moments ago.
Snowfall has pretty much stopped in the the city. All highways there are clear, and most primary city roads also have been plowed, Bloomberg said. The rest of the streets, he said, would be plowed later today.
He said that if other areas, such as Long Island, can use the city's resources and manpower to recover from the storm, the city is willing to help, Bloomberg said.
People interested in tracking snow removal crews' progress in New York City can check out this city map.
.@nycsanitation crews were out all night and will be working all day to clear the streets. We have 2,200 pieces of equipment out there.

[Posted at 8:58 a.m. ET] Motorists on Long Island - especially eastern Long Island - have had a miserable 14 hours or so. Hundreds of cars have been stuck across Long Island, including on the Long Island Expressway (I-495), the Suffolk County Police Department told CNN's Chris Boyette.
The number of stranded motorists exceeded the number of available and able tow truck operators. Many people have been recovered, but many were still out there early Saturday.
As of 8:15 a.m., the county police department said, the Long Island Expressway and the Sunrise Highway still were closed to non-emergency vehicles. “All the roads in Suffolk County are basically impassable,” a representative said.
See the 7:52 a.m. entry below to read about a Long Island Wal-Mart manager who kept his store open to shelter stranded motorists.
[Updated at 8:39 a.m. ET] New York-area airports are starting to stir - but travelers still will have to wait a while to depart today, if they do at all.
Some cargo flights have resumed at JFK and Newark airports, according to Anthony Hayes, public information officer for the Port Authority of New York and New Jersey.
Hayes says he anticipates commercial flights will resume at JFK, LaGuardia and Newark later today, but customers waiting to fly will need to check their flights with their airlines.

Boston Logan is expected to be closed until at least 3 p.m. today.
[Updated at 8:06 a.m. ET] Yesterday, Massachusetts Gov. Deval Patrick issued a driving ban - with some exceptions - that went into effect at 4 p.m. ET.
CNN's Brandon Miller and CNN meteorologist Dave Hennen sent us the picture below, showing that people seemed to take the order seriously Friday afternoon. It was eerie to see Boston's Hanover Street empty, Miller said, given that it was the evening rush hour.
[Updated at 7:52 a.m. ET] It was a long night for a manager of a Wal-Mart on Long Island. The store closed during the storm Friday, but the manager and other workers let 20 or so stranded motorists take shelter inside overnight.
Manager Jerry Greek told CNN that a number of vehicles had crashed or were stuck in the snow on roads not far from the store in Middle Island, New York.
"People started calling the store from their car, seeing if we were open. ... Naturally we just let them come in," Greek said by phone on Saturday morning.
[Updated at 7:31 a.m. ET] This might help give you an idea why Connecticut's governor would ban travel on all its roads until further notice:
In Hartford, snow plow crews were trying to keep up overnight, but with 4 inches falling per hour at one point, "our crews were not able to see where they were going," Hartford Mayor Pedro Segarra told CNN Friday morning.
Snow plowing was suspended for a time in the capital city. It has now resumed, with crews focusing on roads leading to hospitals. Hartford has received more than 2 feet of snow since Friday.
Connecticut's governor this morning banned travel on all roads - not just highways. Exceptions are made for certain people, such as emergency personnel.
[Updated at 7:21 a.m. ET] Maine already has been hit hard by the storm, getting more than 2 feet of snow in the southern portion - but it has a way to go still, with the snow there not expected to stop until tonight.
One of the biggest challenges there will be storm surges in the state's low-lying southern shoreline, state emergency management director Robert McAleer said.
With strong winds pushing from east to west, 3-foot storm surges are possible there, McAleer said.
"It's prone to damage under these types of conditions, and we're watching that situation very, very closely," McAleer said.
[Updated at 7:14 a.m. ET] Rhode Island is having a tough morning: It may have seen the worst power outage relative to its size, with over 180,000 customers losing electricity service.
Rhode Island banned general travel on highways starting yesterday, but Gov. Lincoln Chafee is urging people to stay off all the roads if travel isn't absolutely necessary - he wants the roads to be clear to help power crews get around and make repairs.
"We all have to do our best, especially with people staying off the roads. It’s critical," Chafee told CNN.
[Updated at 7:01 a.m. ET] If you guessed that you'd have some difficulty flying to the Northeast today, you'd be correct. About 1,700 flights in the area have been cancelled for Saturday alone. Boston's Logan airport are among those closed Saturday morning.
[Updated at 6:52 a.m. ET] Central Connecticut has seen some of the heaviest snowfall so far, so it's not likely that too many people would be in a position to drive. But even if they were able and willing, it'd be against the law.
All roads - not just highways, as you'd often hear in serious storms - in Connecticut are closed until further notice, according to Gov. Dannel Malloy's communications director, Andrew Doba. Exceptions will be made for emergency vehicles capable of snow travel.
It's critical right now that residents stay off the roads, so that our plows can continue their efforts to clear our streets and highways

Hamden, Connecticut, has recorded the deepest accumulation we've seen so far in this storm: 34 inches. The state's capital, Hartford, has recorded 4.4 inches.
[Posted at 6:25 a.m. ET] Hundreds of thousands of people in the Northeast are waking up without power this morning as a monster snowstorm, at times with hurricane-force winds, continues to make its way through the region.
The storm has dropped snow from eastern Pennsylvania to Maine from Friday into this morning and left one man dead and about 650,000 customers without power in the Northeast.
Hamden, Connecticut, leads the snowfall tally so far, with 34 inches. Peak wind gusts have exceeded 80 mph in places, including Cuttyhunk, Massachusetts, which has recorded a gust of 83 mph.
Snowfall is wrapping up in New York City right now. The snow will stop in the Boston area this afternoon, and in Maine tonight, CNN meteorologist Alexandra Steele says.
