The fourth nor'easter of the month hit the city Wednesday and created a slick and snowy evening commute.

A winter storm warning is in effect for all of New York City until 10 a.m. Thursday.

As of 11 p.m. Wednesday, there were 4.5 to 10.5 inches of snow in areas across the five boroughs. Snow totals ranged from 4.5 inches in JFK to 10.5 inches in Bedford-Stuyvesant.

The snow was expected to continue overnight before tapering off to flurries and snow showers by sunrise.

Governor Andrew Cuomo declared a state of emergency in the city as the state ramped up its efforts to prevent power outages.

Cuomo deployed 300 New York National Guard Service members to helps area impacted by the winter weather.

Cuomo also reassured customers that utility companies will stay ahead of the storm to prevent widespread outages.

"They have all assured us that they learned from the last storm," the governor said. "They're more personnel, there's more equipment in place, they're in a better position to handle this emergency. But do I have 100 percent confidence? No, because I have been told this before. And I'm going to be in contact with them all through the day today."

City residents experiencing heat or hot water problems should call 311.

New York City public schools were closed Wednesday. The mayor's spokesperson says schools will be open again Thursday.

Alternate-side parking rules have been suspended citywide through Thursday.

LaGuardia Airport said at approximately 2:15 p.m. Wednesday that all remaining flights at the airport were canceled for the rest of the day.

JFK Airport also canceled hundreds of flights.

Both airports say there are already several cancellations for Thursday as well.

Passengers should check with their individual carrier before heading to the airport.

Most Port Authority Bus Terminal carriers were also suspended due to the storm.

The authority says bus service out of the terminal will resume Thursday.
