Winter Storm Grayson

Published: January 4, 2018 / Updated: March 20, 2018

Winter Storm Grayson is undergoing a winter cyclone process, known as bombogenesis, off of the Eastern Seaboard and is spreading a mess of heavy snow, high winds and blizzard conditions that is expected to heavily impact the East Coast.

The United States Postal Service is currently reporting suspended retail and delivery in parts of Maryland, Georgia, Virginia, South Carolina, North Carolina, and the Northeast.

In addition, logistics partners are anticipating delays of 24 - 96 hours for shipments traveling to and through the affected areas, as well as delays and closures to many facilities on the East Coast. Additional delays are expected once transportation resumes due to the backlog.

[1/4/18 Update]


Damaging wind gusts of over 70 mph are possible in coastal eastern Massachusetts. These gusts, combined with the weight of snow, are capable of widespread power outages, downed trees and some structural damage. Gusts of up to 50 mph are possible in other parts of New England, and the Eastern Seaboard, including parts of Long Island, the Jersey shore, Delmarva Peninsula and Virginia Tidewater. These winds will produce blizzard conditions near the coast from eastern New England to the Virginia Tidewater. While not nearly as strong, wind gusts over 40 mph may persist in parts of New England Friday and Saturday.


The heaviest snow is expected in eastern New England and eastern Long Island, where a foot or more of snow is possible. Accumulations of at least 6 inches are possible as far west as parts of Vermont, western Massachusetts, Connecticut, parts of the New York City Tri-State metro, central and southern New Jersey, coastal Delmarva Peninsula and the Tidewater of Virginia.

Coastal Flooding

Coastal flooding will lead to potentially major impacts along parts of the Massachusetts shoreline Thursday, especially along east, northeast and northfacing shores as water levels are expected to peak about two to three feet above normal at high tide.
