This is a special Breaking News email from CNN:

New York City has banned travel because of the blizzard. Gov. Andrew Cuomo said forecasters now say up to 30 inches of snow could fall in parts of southern New York. He said inbound and outbound Metro-North and Long Island Rail Road trains will stop running around 4 p.m. ET.

"This is bad and it's getting worse rapidly," New York Mayor Bill de Blasio said.

Here are the latest developments on the massive winter storm and blizzard:

Nationwide: 
Eight people have died due to the storm: Six in North Carolina, one in Virginia and one in Kentucky.

Eleven states have declared states of emergency: Georgia, Tennessee, Pennsylvania, Maryland, Kentucky, North Carolina, New Jersey, New York, Delaware, Virginia and West Virginia. Washington has declared a "snow emergency."

More than 8,600 flights have been canceled through Sunday, according to FlightAware.com.

More than 200,000 customers in 13 states are without power because of the storm. Most of them, about 140,000, are in the Carolinas.

 

About 33 million people are under blizzard warnings.

State by state:

New Jersey: "Significant flooding" related to the blizzard forced more than 50 people from their homes around Atlantic City, said Vince Jones, the city's emergency management director. Jones said that an "extremely high" tide and strong winds "really pushed the water up from the ocean onto the streets." 

Washington, D.C.: About 13 inches of snow has fallen and another 10 inches is possible by the time the storm passes, Mayor Muriel Bowser said. Wind gusts of about 50 mph have been reported.

Kentucky: Motorists were stranded along a 35-mile stretch of Interstate 75 for up to 19 hours, from Friday afternoon toSaturday morning. Traffic is reported to be moving again.

Pennsylvania: Cars and buses were stuck on a westbound portion of the Pennsylvania Turnpike between Breezewood and New Stanton, State Police Capt. Brian Milore told CNN. Among them was a bus carrying the Duquesne University men's basketball team. National Guard members are helping the stranded motorists, a post on the turnpike's Twitter feed said.

 

West Virginia: National Guard members were dispatched to help move stuck tractor trailers that blocked a roughly 11-mile stretch of Interstate 77 north of Charleston. The state's emergency management agency said late Friday that the highway was "completely shut down."
