    A noticia da SIC não está 100% correcta.
    O tornado foi classificado como EF5, pois agora vigora a nova escala EF (Enhanced Fujita Scale). É o 1º tornado EF5 desde a introdução da nova escala, e foi o tornado mais forte desde 1999. Na escala antiga seria um F4. A explicação tem a ver com os estragos, muito mais importante na nova escala do que propriamente os ventos. Há um tópico no forum sobre esta escala.

    E os estragos foram o que se vê nas imagens já postadas.

    Twister rated as EF-5
    In addition to the devastation in Greensburg, parts of Oklahoma were reeling from twisters that hit Saturday night. One person died from that storm in the northern town of Ottawa, Kansas.

    The Oklahoma town of Sweetwater, about 225 miles south of Greensburg, was hit hard by a twister that severely damaged a high school and other buildings Saturday. (Watch a 360-degree look at the devastation that twisters left behind in Greensburg )

    Larry Ruthi, meteorologist with the National Weather Service in Dodge City, Kansas, told CNN on Sunday that the tornado that struck Greensburg on Friday night was an EF-5, the highest level in a classification system used by the National Weather Service, and had estimated winds of 205 mph (330 kph).

    The damage path at its widest point was about 1.7 miles (2.7 kilometers), and it tracked for 22 miles (35 kilometers). (Watch an aerial view of the devastation )

    The tornado moved at an average speed of about 20 mph (32 kph) and took about 15 to 20 minutes to wipe out the town, he said.

    Re: Tornado nos Estados Unidos da América

    Two more victims have been found in a small town devastated by a huge tornado in the central US state of Kansas.
    The discovery of one body under rubble and another in a nearby lake takes the death toll to at least 10, officials in the town of Greensburg said.

    Rescue teams also found a survivor on Sunday and are continuing to search for anyone trapped since Friday's storm.

    Many residents have been allowed back for the first time to assess damage to their homes and retrieve possessions.

    They have been told they can only stay until dusk, when they must leave for the shelters where most are staying in nearby towns.

    The authorities have been checking residents' names in an attempt to find out whether more people may be missing.

    An estimated 95% of homes and businesses in Greensburg, a town of about 1,500 people, have been damaged or destroyed.

    A further two people died elsewhere in the state in the course of a weekend of violent storms.

    Efforts 'handicapped'

    City administrator Steve Hewitt confirmed the discovery of two more bodies in Greensburg.

    "That's why we are continuing the search and recovery," he said. "We will continue this through today and tomorrow and hopefully we will find more folks alive."


    The search efforts were delayed on Monday by a leak of anhydrous ammonia, used as fertiliser by farmers, which meant rescue workers had to evacuate part of the town.

    Speaking on Sunday, US President George W Bush declared parts of Kansas a major disaster area and pledged federal aid for reconstruction.

    R David Paulison, director of the Federal Emergency Management Agency (Fema), is expected to tour the area on Monday.

    Fema is working to set up trailers to house families left homeless when winds of up to 205mph (330km/h) tore buildings from their foundations in Greensburg.

    Kansas Governor Kathleen Sebelius also visited the town, which lies about 120 miles (200km) west of Wichita in southern Kansas.

    She said the state's response would be negatively affected because emergency equipment such as trucks, tents and trailers had been sent to Iraq.

    "Not having the National Guard equipment, which used to be positioned in various parts of the state, to bring in immediately is really going to handicap this effort to rebuild," she said, the Associated Press news agency reports.

    Heavy equipment will be needed to move the large amounts of debris left by the tornado, which was classified by the National Weather Service as an F-5, the most powerful category.

    The tornado was described as a "wedge", a particularly wide formation said to be - in this instance - more than one mile in diameter.

    Flood risk

    There were confirmed reports of several more tornadoes in the state over the weekend.

    A man died in Ottawa County, 250 miles northeast of Greensburg, state officials said, and 11 people were injured in the town of Osborne when a tornado hit two restaurants.

    Several homes were damaged and one person was injured by a tornado in western Oklahoma.

    Heavy rain continued to sweep the central US on Monday, leading to flooding in areas including Topeka, capital of Kansas, and south-west Iowa.

    National Guard soldiers have been sent to the area to provide security and to start clearing the debris left by the storm.

    One of the few buildings still standing is the courthouse. The city hall, schools, businesses as well as homes were destroyed.

    Re: Tornado faz sete mortos e 50 feridos no Texas

    Normalmente falamos dos mortos, e esquecemos os vivos. A pergunta que ainda ninguem fez aqui.

    Como é que uma pequena cidade com 1500 habitantes desaparece do mapa e só houve 9 mortos ?

    A resposta:

    Por causa da tecnologia de radares. Mas sobretudo porque havia alguém atento a fazer o seu trabalho.

    Chama-se Mike Umscheid, meteorologista do NWS, que atento ao radar percebeu no último instante uma alteração da trajectória fatal para a cidade de Greensburg. E conseguiu dar um alerta com 20m de antecipação que salvou provavelmente centenas de vidas.

    Excelente reportagem do maior tornado dos últimos 8 anos nos EUA.


    Administradores do fórum, acho que deviam alterar o nome deste tópico para Tornado EF5 de Greensburg no Kansas_2007-05-04
