000 NOUS41 KOKX 311030 PNSOKX Public Information Statement National Weather Service New York NY 600 AM EDT Tue Oct 31 2017 ...THIS WEEK IS WINTER WEATHER AWARENESS WEEK... Please join the National Weather Service and the New York State Office of Emergency Management in promoting winter weather education including safety. The topic for today is heavy snow, which is defined as an average snowfall of at least 6 inches in 12 hours, or 8 inches in 24 hours. Coastal storms, also known as noreasters, can produce heavy snow. They usually form from October through April along the coastal plain from the Gulf of Mexico to the Mid Atlantic coast. The combination of low pressure moving northeast from those areas and high pressure to the north can produce strong northeast winds. Several significant coastal storms have brought blizzard conditions to the region during the past decade... On March 14, 2017, blizzard conditions occurred over portions of northeast New Jersey, the Lower Hudson Valley, and interior Southern Connecticut. Snowfall totals ranged from around 1 to 2 feet across the interior Lower Hudson Valley and interior southern Connecticut, with amounts closer to 1 foot in northeast New Jersey. On February 9th 2017, a rapidly intensifying low pressure system brought blizzard conditions over Long Island, southern Connecticut, and coastal portions of the Lower Hudson Valley. Snowfall amounts ranged from 12 to 16 inches. These conditions brought delays and cancellations to the regions transportation systems as well as numerous accidents on roadways. On January 22nd and 23rd of 2016, a low pressure system developed across the southeast states and rapidly intensified as it tracked along the Middle Atlantic coast. Snowfall amounts ranged from over 2 feet from northeast New Jersey, New York City, and Long Island to around a foot across parts of the Lower Hudson Valley and southern Connecticut. Blizzard conditions occurred across New York City, northeast New Jersey, Long Island, and southern Connecticut. A record 27.5 inches of snow fell at Central Park, which is the biggest snowstorm since observations began in 1869. On February 8th and 9th of 2013...a powerful blizzard brought extremely heavy snowfall to much of central and eastern Long Island. Snowfall rates up to 6 inches per hour during the evening rush hour stranded numerous motor vehicles. Lightning and small hail also occurred at the height of the blizzard. Snowfall totals of 18 to 34 inches occurred away from the immediate south shore of long Island, causing partial roof, house and shed collapses. Brookhaven National Laboratory recorded its biggest single storm snowfall ever, with 30.9 inches. Wind gusts from 45 to 75 Miles Per Hour combined with heavy snow to down trees and cause whiteout conditions. Last winter season featured 30.2 inches of snowfall at Central Park in new york city, which is above the average seasonal snowfall of 25.1 inches.
