NEW YORK - A nor'easter dumped nearly a foot of snow on New York City Thursday, and cold temperatures will linger throughout the rest of the night and into Friday.

The snow has stopped falling in the city, but residents should watch for falling ice from buildings and bridges as temperatures continue to drop.

As of 5 p.m., the National Weather Service reported 10 inches of snow at LaGuardia, 8.3 inches at JFK and 9.5 inches at Central Park.

The temperature was 25 degrees in the city as of 6 p.m. It is expected to fall into the teens as the night goes on.

Things will stay cold throughout Friday. Temperatures will be in the teens for the morning rush, with wind chills ranging from 5 to 10 degrees. The high for the day will be in the 20s.

In a news conference, Mayor Bill de Blasio urged New Yorkers to be extra careful as temperatures dip overnight, creating slippery hazards on roads and sidewalks. 

Governor Andrew Cuomo echoed similar warnings at a press conference earlier in the day in Midtown.

About 2,300 vehicles - plows, salt spreaders and shoveling crews - are hard at work clearing city streets.

Sanitation Commissioner Kathryn Garcia says drivers should stay off the roads to let crews do their job.

Mayor de Blasio says while public schools are closed Thursday, he expects the city to be fully back up and running Friday.

Schools used to be open on all but the most severe winter days. But this is the sixth snow day in the last seven years. The last one was two years ago on January 27, 2015.

All CUNY campuses are also closed Thursday, and there are closures affecting many businesses and private schools.

Alternate side parking rules have been suspended through Saturday to help with the cleanup.

Garbage and recycling pickup is also suspended to aid cleanup efforts.

Flight cancellations and delays are also expected to continue throughout the day at the area's major airports.

There were delays at both JFK and Newark as of 4 p.m., but flights are on time at LaGuardia.

A ground stop order was previously issued at JFK.

Travelers are urged to check with their carriers before heading to the airport.

Con Edison says it's prepared to deal with any power outages that may occur as a result of today's snowstorm.

While the utility company says it's holding up so far, the harsh winter weather does pose a threat to both overhead and underground electrical systems.

To report a power problem, you can call Con Ed's hotline at 1-800-752-6633 or visit coned.com

New Yorkers are also reminded to never go near a downed power line.

The city's Code Blue program is in effect to help homeless people get out of the weather.

The city is also encouraging people to check on elderly neighbors and help people shovel sidewalks.

Tenants who are experiencing problems with heat or hot water in their buildings should call 311.
