Rare June Nor'easter NYC to Boston

A rare strong coastal storm for June delivered heavy rain, gusty winds and flooding problems from New York City to Boston Thursday night into Friday morning as forecast.

The storm will roll off to the northeast Friday. Rough surf and seas will linger for a time along New England and Long Island.

It's as if Mother Nature thought it was still March or early April with a storm forecast by meteorologists to quickly spin up into a nor'easter.

The non-tropical storm affected areas from portions of New Jersey to eastern Massachusetts with a period of windswept, drenching rain.

Many folks had already noticed the cool air accompanying the system from the eastern Great Lakes to New England Thursday evening. Temperatures were hovering in the low- to middle 50s over much of the region near the coast during the rain.


Enough rain could fall into Friday midday over southeastern New England to cause flash, urban and small stream flooding.

Lesser rain will generally fall over northern New England. Spotty showers and thunderstorms will wrap around the back side of the storm system as it pulls away into Friday evening.

Wind gusts with the storm system, ranging between 30 and 50 mph near the coast, can topple weakly rooted trees and break large tree limbs off.

As a result of the wind and rain, there can be significant travel delays and sporadic power outages.

While the effects of the storm will be brief, an onshore component of the wind (north to northeast) for a time will bring coastal water levels to a foot or two above published values.

Minor flooding is possible at time of high tide along the north shore of Long Island and the eastern shore of Massachusetts.

Fortunately tides are not especially high during this part of the month with a first-quarter moon on June 16.


The storm system assisted in the formation of lines, complexes and individual severe thunderstorms farther south over the mid-Atlantic to the Carolinas on Thursday, following a low-end derecho that swept from the Midwest to southern New Jersey earlier the same morning.

The storms bring the full spectrum of severe weather ranging from damaging wind gusts, flash flooding, hail and frequent lightning to tornadoes.

The storms have already disrupted play at the U.S. Open at Ardmore, Pa. This story was published at 1:00 p.m. Thursday, June 13, 2013 and was updated Friday morning, June 14.
