The shoreline saw the most snow in blizzard-like conditions on Saturday as the storm crept north.
NBC Connecticut has declared Sunday a First Alert Weather Day.
Gov. Dannel P. Malloy (D-Connecticut) was urging people to to stay off the roads on Saturday.
"Big differences in conditions across #CT. I-95/Merritt Pkway experiencing low visibility/high accumulations. Stay off roads if possible," Malloy tweeted.
State police said on Saturday that between 5 am and 10 pm they responded to 149 accidents across the state.
A blizzard warning is in effect for shoreline towns through Sunday morning and National Weather Service has expanded a winter storm warning to the remainder of the state, including northern Fairfield, New Haven, Middlesex and New London counties, as well as Hartford, Litchfield, Tolland and Windham counties.
Areas in northen Connecticut saw 1 to 3 inches, 3 to 6 inches in central Connecticut and up to a foot for the immediate shoreline. A full list of snowfall counts can be found here.
Snow-covered roads made for slick travel conditions along the shoreline roads, like Interstate 95, the Merritt Parkway and Route 8, causing crashes and spinouts. A CT Transit bus in Greenwich crashed into a utility pole, causing outages and injuring one person.
There are 180 closings so far this morning in anticipation of the snowstorm conditions and multiple schools have canceled SATs. Click here to see the list.
A blizzard warning was not issued because of the amount of snow expected, but rather because of the wind combined with the intensity of a snowstorm that can cause low visibility. Winds of over 35 mph and visibility less than 1/4 mile are required for 3 consecutive hours for a storm to be classified a blizzard.
Fairfield and New Haven Counties were under a coastal flooding warning, but that has been canceled and its been downgraded to a flood advisory. There's moderate coastal flooding during the time of high tide Saturday morning.
Snow started falling in the area just before 5 a.m on Saturday. Snow accumulated on the beach and the white-capped waves were getting bigger as they creep further up the beach.
“With the high tide coming in, the wind that’s supposed to be coming in we’re supposed to have a pretty significant tidal rise," West Haven Deputy Fire Chief Scott Schwartz said.
Minor coastal flooding is anticipated late Saturday evening during high tide along the entire Connecticut shoreline.
The bull's-eye of 1 to 2 feet plus was far south of Connecticut, in places like northern Virginia and western Maryland. A blizzard warning was issued for Washington D.C., and Long Island -- only 20 miles from Connecticut.
Dry weather is expected Sunday and Monday before a warm-up arrives Tuesday, with rain showers possible.
