NEW JERSEY – A winter storm warning and snow alerts have expanded to 17 New Jersey counties as the National Weather Service says more of the state may be impacted by a Monday storm packing nearly a foot of snow. Commercial travel restrictions were in place as the snow was piling on major roads (see expected snow totals below).

The National Weather Service has released its estimations of snow, wind, rain and temperatures for the storm, broken down county-by-county. Read more: NJ Weather: Timeline, Hour-By-Hour Forecast Of NJ Snowstorm

Gov. Phil Murphy was set to address the storm operations at 11 a.m. on Monday. Watch live here:

Enough snow – 8 to 12 inches in spots – could fall to close schools or delay openings. Hundreds of schools were already closed even though the bulk of the snow is expected to hit between 8 a.m. and 6 p.m. on Monday.

Already, the snow and ice was causing travel problems and crashes on New Jersey roads. A major accident – a tractor trailer rolled over – shut down I-80 westbound on Sunday, which later reopened (see list of road conditions below).

Hundreds of flights were cancelled at Newark and other airports, and traffic was jammed on major roads.

A winter weather advisory, which will expire between 4 and 7 a.m. on Tuesday, was also issued for Monmouth, Ocean, Burlington, Camden, Gloucester, Hudson, Essex, Union, Somerset, Mercer and Hunterdon counties.

A winter storm warning was issued for Bergen, Passaic, Sussex, Morris, Warren, Middlesex and Mercer counties. The warning was set to expire between 4 and 7 a.m. on Tuesday.

A coastal flood advisory was also in effect in Ocean and Monmouth counties until 4 p.m. on Monday. Here are the alerted areas:

A commercial vehicle travel restriction on portions of I-78, I-80, and I-287 was issued beginning at 12 midnight on Monday. The restriction applies to the entire length of all interstate highways in New Jersey including:



Interstate 80, both directions from the Pennsylvania state line to Exit 43 (I-287)

Interstate 78, both directions from the Pennsylvania state line to Exit 29 (I-287)

Interstate 287, both directions from Exit 21 (I-78) to the New York border

The commercial vehicle travel restriction in New Jersey applies to the following vehicles:

All tractor-trailers

Empty straight CDL-weighted trucks

Passenger vehicles pulling trailers

Recreational vehicles

Motorcycles

The restriction DOES NOT apply to:

New Jersey Turnpike

Garden State Parkway

Atlantic City Expressway

The Department of Transportation is reminding motorists:

Avoid unnecessary travel during the storm

Consider telecommuting on Monday, if possible

If you must drive and road conditions deteriorate, GET OFF THE ROAD somewhere safe and wait it out

Always STAY CLEAR of plows and spreading trucks. If they are behind you, let them pass

DO NOT PASS between trucks that are in a plow formation

Be patient and use caution

Murphy, speaking during a Sunday press conference, stopped short of issuing an emergency declaration but said the state is "closely monitoring" the system since Thanksgiving weekend travel could be heavy (watch press conference below).



The State Police said it has deployed much heavier patrols on the roads, and Murphy said ice and sleet on Sunday and snow on Monday could lead to power outages. The governor said brine trucks have been out on state highways for days.

Murphy recalled a storm that slammed New Jersey in November 2018 that made him the target of criticism because of his underwhelming response, adding: "We are committed to not letting that happen again."



"This storm will bing a wintry mix and significant accumulations," Murphy said. "We know the forecast can change quickly with a storm like this so we are monitoring it quickly."

Here is what you should expect:



Total snow accumulations of 5 to 9 inches – a slight tick downward from the original prediction of 5 to 11 inches – and ice accumulations of up to one-tenth of an inch are possible.

The bulk of the snow in North Jersey is expected to fall between 8 a.m. and 6 p.m. on Monday.

Rain is expected to change to snow by-mid-day Monday in Central Jersey, South Jersey and the Jersey Shore. As many as 2 to 4 inches may fall.

Untreated surfaces may become hazardous, with the most travel impacts along and north of I-78

Travel could be very difficult throughout this period. The hazardous conditions could impact holiday return travel on Sunday and the commute periods on Monday.

Here are the expected snow totals, which have grown since Saturday morning:

Here is the estimated ice accumulation:

The troublesome combination of heavy rain, ice, snow and strong winds may hamper travelers during their Monday commute, since the major storm will add to travel stress on the roads and at the airports, according to AccuWeather.

Forecasters are calling it a double-barreled storm that will first spread rain, ice and snow into the northeastern United States, according to AccuWeather.

During Monday, cold air is likely to collapse toward the mid-Atlantic and southern New England coast to bring a change to accumulating snow, according to AccuWeather.

While an accumulation of a coating to an inch or so is possible around Philadelphia, up to a few inches may fall on New Jersey and the New York City area with several inches likely around Boston, according to AccuWeather. Much heavier snow is likely in the northern and western suburbs of New York City and Boston.



Should the storm strengthen a bit more, heavy snow may fall right in New York City and North Jersey and a few inches might occur in Philadelphia on Monday, according to AccuWeather. Boston could pick up a foot of snow in such a case where rain does not hold back the accumulation.

Those with flights into or out of the region on Monday, especially from Philadelphia, Newark, New York City and Boston, should expect delays and be prepared for flight cancellations, according to AccuWeather.

Important tips to remember when preparing for winter weather:

Be prepared! Visit ready.nj.gov for information on how to prepare for: home, work, and your vehicle. Have an emergency kit/go-bag for all three locations.

Pets are family too! Remember to include them in your emergency plans. Visit animalemergency.nj.gov to find out more.

NEVER use a generator inside homes, garages, crawlspaces, sheds, or similar areas, even when using fans or opening doors and windows for ventilation. Deadly levels of carbon monoxide can quickly build up in these areas and can linger for hours, even after the generator has shut off.

Test smoke and carbon monoxide detectors to make sure they are working before a storm.

Know how to report a power outage to your utility company.

Have cash on hand. If the power is out, so are the ATMs and credit card machines.

Charge your cell phones and try not to use them if the power goes out. Texting uses less power than a phone call, so send text messages to save power if possible.

Be sure to keep an adequate amount of gas in your car.

Be sure to check on friends and neighbors who have access or functional needs.

Need a warming center? Call NJ 2-1-1 or visit www.nj211.org to get connected!

Be sure to have extra medications on hand and keep them in a water-resistant container.

Get all of your vital records and insurance papers together now. Keep them in a water-resistant container. If you can, scan and email them to yourself so you have a copy of important numbers and policies.

Discuss business continuity plans now. Whether you are the boss or report to a boss, discuss your game plan for continued business operations.

Here are a few tips if you must drive during or after winter weather:

Check 511nj.org for traffic updates before you hit the road.

Be sure to have a full tank of gas before you start your trip.

Follow directions from local officials.

Take it slow!

Don't crowd the plow! Give them plenty of room to work and never pass a snow plow on the right.

Keep a winter weather kit in your car, containing an ice scraper, blanket, flashlight with extra batteries, bag of kitty litter, shovel and charged cell phone, as well as reflective triangles or flares, cloth or paper towels and jumper cables.
