Winter Storms
Nor'easter Explained: Coastal Storms, Wind, Snow, Rain, and Flooding
What a nor'easter is, why it affects the East Coast, and how wind direction, ocean moisture, and storm track shape impacts.
Quick answer: A nor'easter is a strong coastal storm named for the northeast winds it can bring to parts of the coast.
The coastal setup
Nor'easters often strengthen near the East Coast where ocean moisture, temperature contrasts, and upper-level energy combine.
Depending on track and temperature, impacts can include heavy snow, rain, coastal flooding, beach erosion, and strong wind.
Track matters
A small track shift can change snow to rain, move the heaviest band, or increase coastal flooding.
Warm ocean air can keep the immediate coast rainy while inland areas get snow.
Preparation
Watch winter storm, high wind, coastal flood, and marine products together.
Impacts can last through multiple tide cycles if the storm slows down.
