The powerful nor'easter that blasted the tri-state with blinding snow and bitter winds has moved off the coast, but the lingering cold blast will combine with subzero windchills to create hazardous, icy conditions on roads and sidewalks into the weekend.
The storm left behind some of the coldest conditions the tri-state has seen in years. Before the bitter cold eases midday Saturday it will be as cold as 20 below zero with windchills, but the temperature is expected to start rising around noon.
An icy, wintry mix is possible Sunday from late morning until early afternoon before warmer air moves in. The high Saturday is expected to be 29 and 45 on Sunday.
Authorities warned that the cold could lead to frostbite and hypothermia for anyone who is outside for extended periods.
The city enacted its cold weather emergency protocols to shelter the city's homeless Friday night. Overnight, homeless adults can go to any of the city's shelters and beds will be available to walk-ins and people brought in by outreach workers.
At least one NYCHA complex dealt with a loss of power, heat and hot water in the icy weather. Nine buildings at the Claremeont Consolidated Houses were without power and heat Friday afternoon. City crews and the Red Cross worked at the apartments into the evening.
The cold weather came as the city was still cleaning up snow from the nor'easter.
Authorities sent out hundreds of plows and salt trucks overnight Thursday into Friday morning to tackle the 8 to 12 inches of snow that piled up from southern New Jersey to Long Island, forcing the shutdown of the New York City public school system, highways and area airport operations for a time.
Most streets were plowed by midday Friday, but officials urged New Yorkers to take mass transportation as work to salt the icy roads and sidewalks continued.
The storm brought icy high tides that flooded parts of the Jersey Shore. Police in Monmouth Beach said three people, including a mailman, were rescued after their vehicles hit high water on low roads.
Nationwide, at least 15 deaths were blamed on the storm, including three in New York.
By Monday, temperatures are expected to plummet again into the high teens.
