Another nor'easter is expected to drop snow and rain on the city Wednesday, although the snowfall totals will not be as significant as first anticipated.

The city sanitation department has issued a Snow Alert. That means crews are getting plows and equipment ready and coordinating response efforts before the first flakes begin to fall.

New York City public schools will stay open Wednesday.

If the temperature is warm enough Wednesday, the city would see more rain and less snow. But if the opposite happens, the city would see more snow.

An area of low pressure that was originally out in the Great Lakes has been transferring its energy to a new area of low pressure, which, as of this writing, is developing off the East Coast. It is expected to move to the north and east but track close enough to the coast that enough warm air should come in off the Atlantic Ocean to mix in a significant amount of rain.

The forecast

NY1 is forecasting that most of the city will see 3 to 6 inches of snow Wednesday, with low amounts — 1 to 3 inches — possible along the ocean in Brooklyn and Staten Island, with more rain mixing in for those areas. The Bronx will see the most snow.

Earlier forecasts called for 6 to 12 inches of snow for the city overall.

Snow is forecast to start Tuesday night with a few flakes or rain, but steady snow and rain will develop between 6 a.m. to 8 a.m. Wednesday.

Rain and snow is projected to divide the city in half around 8 a.m. Wednesday, as Brooklyn and Queens will possibly see rain at that time.

Heavy snow and rain is likely between 11 a.m. and 6 p.m. Wednesday, tapering off before midnight Wednesday.

• Which Borough Will Get the Highest Snow Totals?

The National Weather Service has issued a Winter Storm Warning for most of the five boroughs, Tuesday night through Wednesday. A Winter Weather Advisory is in effect for the southern half of Queens.

Heavy, wet snow is projected in the city, along with wind gusts of about 40 miles per hour. Some rain is expected as well.

The last nor'easter, which hit the city Friday, brought winds gusts that were close to 70 MPH at their peak. That storm was a mixture of heavy rain and snow, with little accumulation.

The roads will likely be wet when the storm starts Wednesday, but that is projected to change as the day goes on and the snow accumulates.

The department also said it has more than 293,000 tons of salt available.

The city's emergency operations center will activate Wednesday morning to coordinate storm response with all of the city's agencies.

Normal garbage collection is currently scheduled for Wednesday, but they may be delayed depending on how much snow falls.

Alternate Side Parking will be suspended Wednesday and Thursday.

A Hazardous Travel Advisory will be in effect Wednesday. City officials encourage residents to take mass transit as much as possible.
