- The impact of the storm is expected to be felt from Monday night through Wednesday. Residents are urged to stay vigilant and be prepared for any eventualities.
According to the National Weather Service (NWS), heavy snow rates, with some areas experiencing more than 5 cm (2 inches) of snow per hour, along with strong winds, will result in dangerous to impossible travel conditions.
The heavy and wet nature of the snow, combined with maximum wind gusts of up to 80 km/h (50 mph), could also result in scattered to widespread power outages and tree damage.
The impact of this Nor’easter could also be felt along the I-95 corridor from New York City to Boston.
March Nor’easters tend to favor elevated terrain, which means that the heaviest snowfall totals are expected in the Catskills and southern Adirondacks in New York State, the Berkshires and Worcester Hills in Massachusetts, the Monadnocks and White Mountains in New Hampshire, and the southern Green Mountains in Vermont. Some areas could receive localized maximum totals of 60 – 75 cm (24 – 30 inches) of snow.
Furthermore, meteorologists warn that the low pressure could stall and deepen off the coast of New England, leading to widespread minor coastal flooding and beach erosion that could last until Wednesday, March 15.
This Nor’easter is expected to bring significant disruptions to daily life, and residents are being advised to take precautions and stay tuned to weather updates. Travel should be avoided where possible, and residents are encouraged to stock up on essential supplies in case of power outages or road closures.
