    Furacão Irma deixa duas ilhas praticamente destruídas

    O furacão Irma atingiu as Caraíbas, deixando a ilha de Barbuda "totalmente devastada" e 95% da parte francesa de Saint-Martin, nas Antilhas Pequenas, destruída.

    A pequena ilha de Barbuda, nas Caraíbas, foi "totalmente devastada" pela passagem do Irma, que causou a morte de uma pessoa, segundo o primeiro-ministro de Antígua e Barbuda, Gaston Browne.

    "Por enquanto temos apenas registo de uma morte", disse Browne. No entanto, o furacão de categoria 5 causou a destruição da ilha que tem 1600 habitantes, que agora "não é mais que um monte de destroços".

    Também nas Caraíbas, a parte francesa da ilha franco-holandesa Saint-Martin ficou "95% destruída" com a passagem do Irma, disse na quarta-feira à noite o presidente do conselho territorial local, Daniel Gibbs.

    "É uma catástrofe enorme. 95% da ilha está destruída. Estou em choque. É uma loucura", declarou ao telefone com a Rádio Caraíbas Internacional.

    O prefeito do departamento de Guadeloupe, Eric Maire, já tinha informado que há registo de pelo menos seis mortos em Saint-Martin.

    o ciclone Irma é a tempestade perfeita... isto vai ser uma catástrofe.

    O amasso nas pequenas ilhas é enorme, não se vê muita destruição porque são ilhas pouco habitadas... nas grandes metrópoles da florida vai ser diferente.

    Muito embora se creia que a passagem por Cuba possa "amansar" o bicho, a verdade é que, se as previsões de temperatura da água se mantiverem, provavelmente o que perder na passagem por Cuba vai ganhar até atingir a Florida (principalmente o arquipélago Florida Keys).

    Hurricane Irma Discussion Number 33
    NWS National Hurricane Center Miami FL AL112017
    500 AM AST Thu Sep 07 2017

    Irma has become a little less organized during the past few hours.
    Data from an Air Force reserve Hurricane Hunter aircraft near 0500
    UTC indicated that the central pressure had risen to 921 mb and
    that the winds had decreased both at the 700 mb flight-level and in
    surface
    estimates from the Stepped Frequency Microwave Radiometer.
    Since that time, the eye has become cloud filled and the central
    convection has become somewhat ragged. The initial intensity is
    lowered to 155 kt, and this could be a little generous.
    The next
    aircraft is scheduled to reach Irma around 1200 UTC.

    The initial motion is 290/15. The hurricane is currently being
    steered by the subtropical ridge to the north, and for the next
    48 h or so this motion is expected to continue with a decrease in
    the forward speed. After 48 h, a mid- to upper-level trough
    digging into the eastern United States is expected to create a
    break in the ridge and allow Irma to turn northward. The timing of
    the turn is the most important question and one still filled with
    uncertainty. The UKMET, UK Ensemble mean, and the NAVGEM are the
    models showing the latest turn, and they forecast Irma to move into
    the southeastern Gulf of Mexico and near the west coast of the
    Florida Peninsula. The ECMWF and ECMWF Ensemble mean are in the
    middle of the model pack and show Irma moving over the southeastern
    portion of the Florida Peninsula. The GFS, Canadian, and GFS
    Ensemble mean show the earliest turn and show Irma moving east of
    the coast of Florida toward the southeastern United States. The
    new forecast track will best follow the ECMWF, as well as the
    Florida State Superensemble and the HFIP Corrected Consensus, and
    it calls for the center to move over portions of the southeastern
    Florida Peninsula between 72-96 h and then across the Atlantic into
    southern South Carolina by 120 h. Users are again reminded not to
    focus on the exact track since the average NHC track errors at days
    3, 4, and 5 are about 120, 175, and 225 miles, respectively.

    Irma should remain in warm-water, and a low shear environment for
    about the next three days, and thus is expected to remain a strong
    hurricane, most likely Category 5 or 4. Fluctuations in intensity
    are likely during the time due to internal eyewall replacement
    cycles. The large-scale models suggest that shear could increase
    starting at about 72 hr. However, due to the uncertainty as to
    whether this will happen, the intensity forecast keeps Irma at
    category 4 strength until landfall in Florida. The 96-120 h points
    now have a lower intensity due to the forecast of shear and land
    interaction, but Irma is still expected to be a hurricane when it
    reaches the southeastern United States.

    Since Irma is moving away from Puerto Rico and the radars there, the
    hourly position estimates are discontinued after this advisory.

    THURSDAY 7TH SEPTEMBER, 2017 AT 6AM EDT.

    ….EYE OF IRMA MOVING WEST-NORTHWEST OFF THE NORTHERN COAST OF THE DOMINICAN REPUBLIC…

    A HURRICANE WARNING IS NOW IN EFFECT FOR THE ENTIRE BAHAMAS AND THE TURKS AND CAICOS ISLANDS.

    A HURRICANE WARNING MEANS THAT HURRICANE CONDITIONS CAN AFFECT THE AFOREMENTIONED ISLANDS WITHIN 36 HOURS.

    AT 5AM EDT, THE CENTER OF HURRICANE IRMA WAS LOCATED NEAR LATITUDE 20.0 DEGREES NORTH AND LONGITUDE 68.3 DEGREES WEST OR ABOUT 210 MILES SOUTHEAST OF THE TURKS AND CAICOS ISLANDS, 330 MILES SOUTHEAST OF MATTHEW TOWN INAGUA AND 670 MILES SOUTHEAST OF NEW PROVIDENCE.

    HURRICANE IRMA IS MOVING TOWARD THE WEST-NORTHWEST AT ABOUT 17 MPH AND THIS GENERAL MOTION IS EXPECTED TO CONTINUE WITH SOME DECREASE IN FORWARD SPEED FOR THE NEXT COUPLE OF DAYS. ON THE FORECAST TRACK, THE CENTER SHOULD PASS NORTH OF THE COAST OF HISPANIOLA LATER TODAY, BE NEAR THE TURKS AND CAICOS ISLANDS AND THE SOUTHEASTERN BAHAMAS BY THIS EVENING, AND THEN BE NEAR THE CENTRAL BAHAMAS BY FRIDAY.

    MAXIMUM SUSTAINED WINDS REMAIN NEAR 180 MILES PER HOUR WITH HIGHER GUSTS. IRMA IS A CATEGORY FIVE HURRICANE ON THE SAFFIR-SIMPSON HURRICANE WIND SCALE. SOME FLUCTUATIONS IN INTENSITY ARE LIKELY DURING THE NEXT DAY OR TWO, BUT IRMA IS FORECAST TO REMAIN A POWERFUL CATEGORY FOUR OR FIVE HURRICANE DURING THE NEXT COUPLE OF DAYS.

    HURRICANE FORCE WINDS EXTEND OUTWARD UP TO 50 MILES FROM THE CENTER AND TROPICAL STORM FORCE WINDS EXTEND OUTWARD UP TO 185 MILES FROM THE CENTER.

    RESIDENTS IN THE TURKS AND CAICOS ISLANDS SHOULD BEGIN TO FEEL THE EFFECTS OF HURRICANE IRMA BY 10AM TODAY, THESE CONDITINS SHOULD SPREAD INTO INAGUA BY 4PM THIS AFTEROON AND INTO MAYAGUANA, CROOKED ISLAND, ACKLINS AND RAGGED ISLAND BY TONIGHT. THEREFORE, RESIDENTS IN THESE ISLANDS SHOULD HAVE ALREADY COMPLETED ALL PREPARATION FOR HURRICANE IRMA AND ARE STRONGLY URGED TO REMAIN INDOORS DURING THE PASSAGE OF IRMA.

    RESIDENTS IN LONG ISLAND, RUM CAY, SAN SALVADOR, THE EXUMAS AND CAT ISLAND, COULD BEGIN TO FEEL THE EFFECTS OF HURRICANE IRMA BY NOON ON FRIDAY.

    RESIDENTS IN NEW PROVIDENCE, ELEUTHERA, ANDROS, BERRY ISLANDS, BIMINI, GRAND BAHAMA AND ABACO SHOULD RUSH TO COMPLETE ALL PREPARATION FOR HURRICANE IRMA.

    EXTENSIVE TO SEVERE FLOODING CAN BE EXPECTED AS IRMA IS FORECAST TO PRODUCE RAINFALL AMOUNTS OF 8 TO 12 INCHES.

    THE COMBINATION OF DANGEROUS STORM SURGE AND LARGE DESTRUCTIVE WAVES CAN RAISE WATER LEVELS BY AS MUCH AS 15 TO 20 FEET ABOVE THE NORMAL TIDE. RESIDENTS LIVING NEAR THE COAST ARE ASKED TO MOVE TO HIGHER GROUND INLAND.

    SMALL CRAFT OPERATORS THROUGHOUT THE BAHAMAS AND THE TURKS AND CAICOS ISLANDS SHOULD IMMEDIATELY SEEK SAFE HARBOUR FOR THEIR VESSELS.

    THE NEXT ALERT ON HURRICANE IRMA WILL BE ISSUED AT 9AM EDT ON THURSDAY 7TH SEPTEMBER 2017
