    Cool [Aquecimento global] Frio polar faz Nova York decretar alerta meteorológico



    A cidade de Nova York está sofrendo nesta sexta-feira (12) uma onda de frio polar que se intensificará neste final de semana, o que motivou as autoridades a ditar um alerta meteorológico que estará vigente até o meio-dia do domingo.

    As temperaturas começaram a cair desde ontem à noite, e ao meio-dia de hoje na estação de Central Park, que costuma ser tomada como referência para a cidade, os termômetros registravam seis graus centígrados negativos.

    Além disso, a previsão meteorológica indica que a temperatura que se espera para a manhã do domingo é de -15ºC, com uma sensação térmica de -24ºC pelos ventos gelados que estão afetando à cidade.

    O Serviço Meteorológico dos Estados Unidos disse que as piores temperaturas serão registradas desde as 16h do sábado (hora local, 19h de Brasília) até o meio-dia do domingo.

    Os meteorologistas esperam ventos procedentes do noroeste de entre 32km/h e 48 km/h, com sequências de 77 km/h, segundo a agência federal, que advertiu que uma exposição prolongada à onda de frio pode causar congelamento.

    O frio começou a chegar nesta quinta-feira, quando se alcançaram as temperaturas mais baixas da temporada invernal, mas elas vão cair progressivamente até no domingo.

    A temperatura mais baixa registrada na temporada invernal anterior foi de -16ºC.

    Alerta do prefeito

    O prefeito da cidade, Bill de Blasio, alertou sobre a onda de frio e pediu aos moradores de Nova York que levem "muito a sério" as advertências para evitar uma exposição prolongada.

    A onda de frio polar afeta também o sul do estado de Connecticut, o nordeste de Nova Jersey e o vale do rio Hudson, no estado de Nova York.

    No último dia 23 de janeiro, Nova York sofreu uma das piores tempestades de neve na história recente da cidade, mas as temperaturas foram mais altas que as que se esperava para este fim de semana.

    Northeast to be hit by 'coldest temperatures in a decade'


    Arctic blast predicted to send many cities' temperatures below 0F (-18C)



    12:53 GMT, 13 February 2016

    New York was hit by an arctic blast this morning as freezing temperatures and biting windchill struck the east coast.

    Temperatures plummeted to below zero (-18C) in New York state as windchill made it feel as cold as -22F (-30C)

    New York City itself was 19F (-7C) as people woke this morning, but it felt more like 4F (-16C) as a polar vortex began to sweep across the east of the United States.

    Mayor Bill be Blasio warned New Yorkers to take 'extreme precautions' today and on Sunday, which could see the coldest temperatures in a decade for much of the Northeast as forecasters warned of 'life-threatening' subzero conditions.

    In Buffalo it was -1F (-18C), with a mammoth windchill making it feel 21 degrees (-6C) colder. That temperatures was expected to drop another couple of degree this morning as flurries of snow came down.

    A wind chill advisory was in effect for New York City beginning Saturday afternoon and continuing to noon Sunday, with the forecast predicting temperatures of 2F (-17C).

    Wind chills are expected to drop 18F (-8C) to 24F (-4C) below across the region and wind gusts may reach 45mph.

    But the Big Apple will have it easy compared to the likes Boston, with a low at 2 degrees below zero, and temperatures in Worcester, Massachusetts to drop as low as -11F (-24C).




    Weather Channel Forecaster Michael Palmer said anyone who dares step outside Sunday morning will feel like they're 'walking into a freezer'.


    'This will be the coldest air for more than a decade,' he told NBC News.

    The National Weather Service warned that residents take precautions to protect themselves from frostbite or hypothermia conditions.

    De Blasio told New York residents to heed cold-weather warnings, adding that city workers would also bring people living on the street to shelters or hospitals.

    The anticipated temperatures were so cold the Central Park Conservancy decided to cancel the annual Central Park Ice Festival, meant to be held on Saturday.

    It was the second time the weather dampened fun in Central Park.

    Last month a free winter sports day called Winter Jam was canceled because of Storm Jonas.

    Lighter winds and sunshine will greet the city on Sunday, but temperatures are still expected to be in the single digits, according to AccuWeather.

    Meanwhile, a midwinter heat wave is smashing records in California.

    Temperatures on the southern West Coast rocketed into the 90s for the second consecutive day on Tuesday even as the warming Santa Ana winds that came in on Saturday began to fade.

    Forecasters said strong high pressure will continue through the week, keeping afternoon temperatures well above normal until at least Valentine's Day on Sunday.
