Nor’easters: How they form and why they trigger weather emergencies<\/p>\n
Nor’easters are major storms that often push up the East Coast of the U.S. and bring major disruptions to the Northeast with snow, flooding and more.<\/p>\n
A coastal storm that could become the season\u2019s first Nor\u2019easter is moving up the East Coast this weekend, potentially affecting areas from Florida to Massachusetts.<\/p>\n
Forecasters say its strength and exact path will determine how severe the impacts are in New York. Coastal communities from the Carolinas to the Mid-Atlantic could face higher tides, strong northeast winds and beach erosion \u2014 especially if the storm tracks closer to the shore.<\/p>\n
“The main concern continues to be with the potential of a strong coastal low Sunday into early next week,” according to the National Weather Service office in New York. “There is still a large amount of uncertainty with impacts which are dependent on the exact track and intensity of a deepening<\/a> low pressure Saturday night into Sunday near the Carolinas\/Southern Middle Atlantic coast. How far north the low tracks along with its strength later Sunday and Monday will be the main determining factors for potential wind and coastal flood<\/a> impacts.”<\/p>\n What is a Nor’easter?<\/p>\n A Nor\u2019easter is a storm along the East Coast of North America<\/a> that typically blow over coastal areas. These storms can occur at any time of year but are most frequent and most intense between September and April, according to the National Weather Service.<\/a><\/p>\n Nor\u2019easters usually develop between Georgia and New Jersey, within about 100 miles of the coast, and generally move northeastward, reaching maximum intensity near New England and the Canadian Maritime Provinces. They often bring heavy precipitation \u2014 rain or snow \u2014 along with gale-force winds, rough seas and sometimes coastal flooding.<\/p>\n Potential impacts of the Nor\u2019easter in New York<\/p>\n How do Nor\u2019easters develop?<\/p>\n The U.S. East Coast provides an ideal environment for Nor\u2019easters. In winter, the polar jet stream pushes cold Arctic air south across Canada and the U.S., then east toward the Atlantic Ocean, according to the National Weather Service<\/a>. At the same time, warm air from the Gulf of Mexico and the Atlantic moves northward. The contrast between the cold land air and relatively warm coastal waters \u2014 kept mild by the Gulf Stream \u2014 fuels these storms, creating the strong winds and precipitation that define a Nor\u2019easter.<\/p>\n Do Nor\u2019easters always have snow?<\/p>\n No. Whether a Nor\u2019easter brings snow, rain, or a mix depends on the storm\u2019s track and temperatures:<\/p>\n Even without snow, Nor\u2019easters can still produce\u00a0strong winds, heavy rain, rough seas and coastal flooding, making them dangerous storms regardless of the type of precipitation.<\/p>\n Why is it called Nor’easter?<\/p>\n It\u2019s called a\u00a0Nor\u2019easter\u00a0because of the direction of the prevailing winds during the storm. In these systems, the winds along the coast usually blow from the\u00a0northeast.<\/p>\n How do Nor’easters differ from tropical storms or hurricanes?<\/p>\n Nor’easters are typically associated with colder seasons and form from a temperature contrast between cold Arctic air and relatively warm Atlantic waters.<\/p>\n Tropical storms and hurricanes form over warm tropical or subtropical waters, and predominantly develop in warmer months.<\/p>\n Nor’easters also have a larger wind field, while tropical storms have a well-defined eye with the strongest winds near the center.<\/p>\n New York weather watches and warningsStay informed.
