The winter storm that has left parts of the country covered in snow has finally arrived in New York City in the form of heavy rain. 

Temperatures rose last night and into Sunday morning to a high of 45 degrees, however, temperatures are expected to plummet suddenly later today, causing wet roads and sidewalks to freeze by the afternoon. It will be in the 20s before 5pm.

Tonight: the city will see freezing temperatures with lows in the single digits. The skies will be clear and the wind chill will drop below zero.

For Tomorrow: expect frigid weather with sunshine and a high in the teens. Also, brisk winds will make it feel colder.

Checking the extended forecast: The cold continues on Tuesday and so will the sunshine. The high will be 28 degrees. Then on Wednesday, the city will see wet and warmer weather. The high will be in the 40s. On Thursday and Friday, rain chances will linger. 

HEATING AND SAFETY

The mayor is also urging New Yorkers, who are already having difficulty with their heat and hot water, to notify 311 so the city can try and rectify the situation.

Call 311 or log on to NYC.gov if you have heating complaints. According to the city, landlords are required to maintain the heat inside at 68 degrees Fahrenheit or above when the temperature is 55 degrees or below outside between 6 a.m. and 10 p.m.

• What precautions should you take to say safe during bitter cold?

Between 10 p.m. and 6 a.m., landlords are required to maintain the heat inside at least 62 degrees Fahrenheit or above, regardless of the temperature outside.

The city is reminding New Yorkers to call 311 if they see a person living out on the street, as a person can suffer frostbite in 30 minutes.

HOW TO WINTERPROOF YOUR CAR

With temperatures rapidly dropping tonight, Triple A is warning drivers about the cold, and you still have time to make sure your vehicles are ready for it.

The association says single digit temperatures can cause car batteries to die and can lower tire pressure.

If you have to drive, Triple A recommends a winterizing checklist: Make sure your tires are properly inflated; Do not use cruise control while driving on any slippery surface; If possible, avoid using your parking brake in cold, rainy and snowy weather; And keep your gas tank at least half full to avoid a gas line freeze-up.
