New Yorkers are being urged to take it slow as yet another nor'easter is creating some slick road and sidewalk conditions across the five boroughs Tuesday.

A Winter Weather Advisory was in effect until noon.

This is the third nor'easter to arrive in the city in less than two weeks.

The forecast

NY1's weather team has forecast 1 to 3 inches of snow for the city. An original forecast Sunday afternoon called for no more than 1 inch of snow, but the storm strengthened Monday.

The snow may mix with rain at times, and may have trouble sticking to the ground.

Eastern Brooklyn and Eastern Queens are projected to see 2 to 3 inches of snow, while the rest of the city should get only 1 to 2 inches.

But overall, the storm is expected to be a low to moderate impact nor'easter.

Flooding and winds

Minor coastal flooding is possible in areas like Broad Channel during high tides.

Sustained winds are projected to peak at 20 to 25 miles per hour, with wind gusts up to 30 to 35 MPH possible.

The winds, in conjunction with wet snow, could bring down tree branches, but power outages similar to what the city saw in the last two nor'easters is unlikely.

By 7 a.m. Tuesday, winds around 16 MPH are expected, getting stronger over the following hours. By Tuesday afternoon, the winds should weaken.

Beyond New York City

The storm will drop more snow east of the city. Eastern Long Island could face 4 to 8 inches snow, and Central Long Island could see 3 to 6 inches.

1 to 2 inches of snow is possible in New Jersey and Rockland, Orange, and Putnam Counties. 1 to 3 inches are forecast Connecticut.

A Blizzard Warning was in effect for Boston.

Temperatures

Temperatures Monday evening will fall into the low 30s.

A high temperature of about 39 degrees is forecast for Tuesday.

The sun is projected to return Wednesday, although a few leftover snow showers are possible. Look for a high of 42 degrees.

The second half of the week looks like it will be dry and cold, with temperatures forecast to be in the 40s.

Due to the weather, the Staten Island Ferry is operating on a modified schedule Tuesday morning.

Amtrak service between New York Penn Station and Boston was suspended until further notice.

Area airports were reporting some delays. 

Passengers are urged to check with their carrier before heading out.
