AccuWeather nails Nor’easter forecast

Written by Elizabeth Potts | Nov 4, 2021

Timely and Accurate Language is Key

When people talk about Nor’easters, they typically picture blowing snow and freezing temperatures. Last week however, it wasn’t snow but rather flooding rain that plummeted the Northeast as an early-season Nor'easter doused the region with heavy downpours and hurricane-force winds. Over half a million people were left without power and parts of New York received more than eight inches of rain. Winds of over 100 miles per hour slammed into coastal Massachusetts, bringing with it a storm surge of nearly 4 feet.

As the storm approached the coastline, AccuWeather meteorologists updated their forecast language to ensure communities had advance warning of the dangerous conditions coming their way. Several days before the Nor'easter arrived, forecasts began including "coastal flooding" for areas of New England, including Massachusetts. By landfall, the risk of significant flash flooding became imminent for residents and businesses. In northern and central New Jersey numerous high water rescues were reported and floodwaters went up to car roofs in some parts.

The Pennsylvania Department of Transportation was alerted by AccuWeather about the threat of flash flooding in their region. Several flash flood warnings in the area were issued where more than four inches of rain fell, creating dangerous conditions for drivers.

In coastal New England, where the worst of the storm hit, our experts warned about significant coastal flooding and strong winds that could bring down trees and power lines. Once again the forecasters’ choice of words made a difference in conveying an important warning to local communities. Our meteorologists’ initial wind gust forecast issued on Sunday morning was spot on– predicting gusts up to 80 miles per hour along the Massachusetts coast. Take a look at how powerful waves smashed into a seawall in Scituate, Massachusetts, crashing down on the roofs of waterside homes.
