On Thursday afternoon, the tide gauge at Boston Harbor matched its record at 15.1 feet -- previously set during the blizzard of 1978.
In Hull, Massachusetts, just to the southeast of Boston, the icy mess inundated street with water above the wheel wells of cars and coming up to the doors of homes.
Some people were forced to flee their homes. In one case, the fire department used a front-loader to rescue a woman from the second floor of her home, a video from neighbor Jennifer Olivieri shows.
Latest developments
• Fast-moving weather: The storm was moving quickly and, fortunately, the center of the system and its highest winds stayed offshore, CNN meteorologist Tom Sater said,
• Snow slows: Forecasters at the National Weather Service said snowfall amounts will diminish in southern New England, but wind and cold temperatures will be threats on Friday.
• Deadly conditions: At least 16 people have died this week due to severe weather, officials said. Six deaths were reported in Wisconsin, four in Texas, three in North Carolina, and one each in Michigan, Missouri and North Dakota.
• Going dark: More than 13,000 people in along the East Coast were without power, according to reports from five states.
• Stay home: Boston Mayor Marty Walsh told residents too many people were getting their cars stuck. "We want to clear the streets."
Roads fill with water
The bomb cyclone, which developed overnight, occurs when a low-pressure system has a significant, rapid drop in atmospheric pressure.
In Quincy, Massachusetts, one street turned into an icy river.
More than 4,300 US flights were canceled for Thursday, according to Flightaware.com. New York's LaGuardia airport reopened later in the day, and JFK International was expected to follow suit on Friday morning. Passengers were urged to check with airlines on flight information.

Extreme winds hamper power restoration
Northeast braces for brutal winter storm 02:48
In Connecticut, Gov. Dan Malloy urged residents to stay off roads. About 2,000 people in the state were without power, he said, and getting the lights back on could take longer than usual because of the wind.
At an evening news conference, the governor said third-shift state employees should go to work Thursday night after the worst of the storm passed.
Between 8 and 16 inches of snow fell, he said.
In Caribou, Maine, the National Weather Service office tweeted a video of strong winds, saying: "Blizzard conditions tonight."
Record-breaking temperatures on the way
Dozens of cities are set to endure record-breaking cold, CNN meteorologist Brandon Miller said.
New York City and Philadelphia will plummet to 3 degrees this weekend. Boston will plunge to 7 degrees below zero -- plus up to a foot of snow.
Winds chills will be well below zero this weekend, with some areas feeling like it is minus 40.
How bomb cyclones work
Bomb cyclones often draw colder air in from the north, then blast out icy temperatures.
They frequently occur in North America, when cold air collides with warm air over the Atlantic Ocean -- though they've also been reported in eastern Asia and South America.
What exactly is a 'bomb cyclone'? 00:52
The bomb cyclone now blasting the Northeast actually doubled the rate necessary to earn it that classification.
It rapidly intensified overnight, undergoing bombogenesis -- or a pressure drop of 24 millibars in less than 24 hours.
This bomb cyclone dropped 53 millibars in just 21 hours, intensifying faster than any such occurrence in recent history.
