Add The New York Times on GoogleAgrega The New York Times en Google The East Coast of the United States hasn\u2019t experienced a hurricane this year, but the storm trudging up the Northeast this weekend may feel like one in some places.This storm is technically a nor\u2019easter, a type of storm that more commonly stirs visions of heavy snow and plunging temperatures.So what\u2019s the difference, and why is this a nor\u2019easter if it\u2019s not going to snow?\u201cNor\u2019easter\u201d applies broadly to storms that move along the Eastern Seaboard with winds that blow from the northeast. These types of storms typically occur between November and March. A nor\u2019easter in September is relatively early, but not unheard of.A nor\u2019easter gets its energy from colliding air masses, like cold, dry air and warm, moist air. On satellite images, it often looks like a large comma. The long tail is the cold air wrapping around the storm\u2019s center \u2014 that\u2019s what causes thunderstorms to form \u2014 while the comma head is where the warm, moist air wraps around. These storms can be enhanced by the jet stream, a ribbon of very strong winds at the cruising altitude of commercial airplanes.AdvertisementSKIP ADVERTISEMENTOften, the National Weather Service will avoid using the word \u201cnor\u2019easter\u201d entirely if the storm doesn\u2019t have a major snow component, because residents in the Northeast so strongly associate the term with snow. Dominic Ramunni, a meteorologist with the Weather Service in New York City, said that the local weather offices and the national centers of the Weather Service had a call Thursday and agreed to all use the same term for this storm so there wasn\u2019t confusion in the media. So, they all began using nor\u2019easter on Friday instead of coastal storm, because nor\u2019easter was already being widely used.Mr. Ramunni said that while weaker than some systems this past year in terms of precipitation and winds, the coastal flooding could rival some of the worst events in the past several years.A hurricane is different: It is fueled by warm ocean temperatures and requires a calm atmosphere to intensify. At times, these storms can be hybrid versions that begin as hurricanes before morphing into more typical storms. A famous example is Hurricane Sandy, which started as a hurricane but then became what is called an extratropical storm \u2014 another name for a typical storm system found across the United States.One way meteorologists monitor a storm\u2019s strength is through its pressure. The lower the pressure, the more intense the storm.Sandy reached an intensity of 940 millibars before it began to transition into an extratropical storm. That transition spread Sandy\u2019s damaging winds out farther than they were as a hurricane. The storm surge had already built up over several days and pushed inland with hurricane force.AdvertisementSKIP ADVERTISEMENTThe storm was essentially a concoction of the worst hazards from both types of systems.This weekend\u2019s nor\u2019easter is not Sandy. Its intensity is peaking around 992 millibars. (For context, a strong nor\u2019easter this past February reached 965 millibars.) This doesn\u2019t diminish this weekend\u2019s potential for coastal erosion, strong winds and rainfall, but the Northeast coast has seen worse.This storm isn\u2019t even named, which is standard for anything other than a hurricane. Sandy only had a name because it was a hurricane first. The National Weather Service does not name winter storms.In Europe, storms that could cause potential damage are routinely named. In the United States, some private organizations and media outlets choose to name winter storms unofficially.AdvertisementSKIP ADVERTISEMENT",
