NEW JERSEY – Forecasters have released the latest hour-by-hour details and snow estimates for a powerful nor'easter that's expected to hit New Jersey after 10 a.m. on Wednesday (see the hour-by-hour details below).

The National Weather Service has now issued a winter storm warning for 13 New Jersey counties, saying heavy snow mixed with ice will create a mess on local roads and highways for Monmouth County and north – especially after 5 p.m.

Gov. Phil Murphy issued a state of emergency for New Jersey, which was to start at 2 p.m. on Wednesday. The declaration triggers executive powers and safeguards, such as imposing shutdowns prohibiting excessive price increases. He also provided the latest details on the storm. Read more: Gov. Murphy Declares State Of Emergency For NJ Nor'easter Snow

The timing of the storm shifted to later in the day; now the nor'easter is expected to hit hardest on Wednesday night and last into Thursday morning.

Many schools could be either close or switch to all-remote learning. Winds as strong as 60 mph could down power lines and cause electrical outages, especially at the Jersey Shore. Roads may be closed, just as shipments of the coronavirus vaccine are coming to New Jersey.

Here are the latest snow estimates:

Here is what to expect from the storm that's expected to impact the region between 10 a.m. on Wednesday and 12 noon on Thursday:

• Heavy snow, mixed precipitation, and rain will affect the region. Snow amounts will be significant near and north and west of the I-95 corridor.
• Snowfall rates could reach 1 to 2 inches per hour for a time late day Wednesday – or after 5 p.m. – and into Wednesday night, causing significantly reduced visibility and potentially crippling travel impacts in places.
• Very strong winds expected near the coast and over the marine zones with gusts potentially reaching 45 to 60 mph. This could result in power outages.
• Inland, gusts could reach as high as 30 to 40 mph, exacerbating visibility restrictions in snow.
• Moderate coastal flooding is possible with Wednesday evening’s high tide and likely with Thursday morning’s high tide along the Atlantic Ocean and lower Delaware Bay. Additionally, minor tidal flooding is possible with Wednesday morning’s high tide.

The storm is expected to be the worst storm since 2018, when ice storms dominated much of the winter. An unexpected storm hit New Jersey during the late fall of that year.

Forecasters are warning that the storm will hit hard and fast with major disruptions to travel and even travel shutdowns, as well as shipping delays, school closings and power outages, according to AccuWeather.

North Jersey and the lower Hudson Valley of New York state through much of Connecticut and northwestern Rhode Island is the most likely zone to experience blizzard and whiteout conditions, according to AccuWeather. Winds can frequently gust between 40 and 60 mph, dropping the visibility to near-zero at times at the height of the storm Wednesday night into Thursday morning, according to AccuWeather.
