 Summary

    A historic and unprecedented early-season winter storm impacted the area on Saturday, October 29, with more than one foot of heavy wet snow falling on interior portions of northeast New Jersey, the Lower Hudson Valley and Southern Connecticut. This is the first time a winter storm of this magnitude has ever occurred in October.

    Late Friday night, October 28, an area of low pressure emerged from the South Carolina coastal plain into the western Atlantic Ocean. The low moved up the coast late Friday night into Saturday morning. The low began to rapidly strengthen late Saturday morning when it was east of the Delmarva coast…and continued to strengthen as it passed south of Long Island Saturday night. With water temperatures in the lower 60s, much of Long Island received mainly rainfall and up to 2 inches of rain during the event. Areas north and west of New York City, however, were just cold enough to support a heavy wet snow. The heaviest snowfall fell along a corridor from northeast New Jersey into central and western New England. In addition to the heavy rain and snow...strong winds wewre experienced along the immediate coastline. In fact, wind gusts of up to 63 mph occurred across Suffolk County, NY late Saturday afternoon and evening as the low passed offshore.

    Thousands of people across New Jersey, southern New York and Connecticut lost power during this event as heavy snow accumulated on trees that still had partial to full foliage during mid-autumn. This caused extensive felling of trees and limbs across the region and damage to power lines.
