What is a Nor’easter? • https://www.youtube.com/watch?v=LGnIQ Dv-ZuM Forecast What is a Nor’easter? “The official definition of a “Nor'easter” is a strong low pressure system that affects the Mid-Atlantic and New England states. It can form over the land of the eastern U.S. or over the Atlantic coastal waters. These winter events are notorious for producing heavy snow, rain, and tremendous waves that crash onto Atlantic beaches, often causing beach erosion and structural damage.” Nor’easter definition continued: www.nssl.noaa.gov/education/svrwx101/winter/faq/ • “Wind gusts associated with these storms can exceed hurricane force in intensity. A nor'easter gets its name from the continuously strong northeasterly winds blowing in from the ocean ahead of the storm and over the coastal areas. What makes them so strong is the warm and moist air from the Atlantic that feeds the storm, causing it to grow explosively.” Nor\'easter Facts: • can form over land or over coastal waters • are winter weather events (October-April) • produce heavy snow, rain, and waves that can cause beach erosion/structural damage • Winds can exceed hurricane force Are Nor’Easters Blizzards? • Not all Nor’easters are blizzards but some do meet the qualifications for being classified as a blizzard: • Large amounts snow/blowing snow • winds > 35mph with • <1/4 mile visibility (> 3hrs) • http://www.accuweather.com/en/weather-news/what-is-a-blizzard/5674708 Satellite image of the intense nor'easter responsible for the blizzard of 2006. Note the hurricane-like eye at the center. How are Nor’easters Formed • http://www.usatoday.com/videos/weather/2014/11/26/19537125/ Nor’easter ingredients 1. Low-pressure system formed over the Gulf Stream current off coast of Florida (warm, moist air); counter-clockwise winds 2.Northeasterly winds bring Low-pressure system up east coast 3. High-pressure system (clockwise winds) blows down from Canada. When two systems meet, precipitation is produced Nor’Easter Storm Dangers • Traffic accidents • Heart attacks while shoveling • Hypothermia from exposure to cold • Frost bite due to wind chill • Beach erosion/damage What would you do? • http://safeshare.tv/w/IAKhZDAJJR
