  • Hurricanes: A guide to the world’s deadliest storms

    As Hurricane Florence approaches the east coast of the United States, use our guide to see how these deadly storms form, their devastating effects and how they are measured.

    Hurricanes

    A guide to the world’s deadliest storms

    Hurricanes are violent storms that can bring devastation to coastal areas, threatening lives, homes and businesses.

    Hurricanes develop from thunderstorms, fuelled by warm, moist air as they cross sub-tropical waters.
    Warm air rises into the storm.

    Air swirls in to fill the low pressure in the storm, sucking air in and upwards, reinforcing the low pressure.

    The storm rotates due to the spin of the earth and energy from the warm ocean increases wind speeds as it builds.

    When winds reach 119km/h (74mph), it is known as a hurricane – in the Atlantic and Eastern Pacific – or a typhoon in the Western Pacific.

    “Everybody has a plan until they get punched in the face. Well, we’re about to get punched in the face.”
    Florida Mayor Bob Buckhorn, ahead of Hurricane Irma (2017)

    The central eye of calmer weather is surrounded by a wall of rainstorms.
    This eyewall has the fastest winds below it and violent currents of air rising through it.

    A mound of water piles up below the eye which is unleashed as the storm reaches land.
    These storm surges can cause more damage from flooding than the winds.

    “Urgent warning about the rapid rise of water on the SW FL coast with the passage of #Irma’s eye. MOVE AWAY FROM THE WATER!”
    Tweet from the National Hurricane Center

    The size of hurricanes is mainly measured by the Saffir-Simpson scale – other scales are used in Asia Pacific and Australia.

    Winds 119-153km/h
    Some minor flooding, little structural damage.
    Storm surge +1.2m-1.5m

    Winds 154-177km/h
    Roofs and trees could be damaged.
    Storm surge +1.8m-2.4m

    Winds 178-208km/h
    Houses suffer damage, severe flooding
    Storm surge +2.7m-3.7m

    Hurricane Sandy (2012) caused $71bn damage in the Caribbean and New York

    Winds 209-251km/h
    Some roofs destroyed and major structural damage to houses.
    Storm surge +4m-5.5m

    Hurricane Ike (2008) hit Caribbean islands and Louisiana and was blamed for at least 195 deaths

    Winds 252km/h+
    Serious damage to buildings, severe flooding further inland.
    Storm surge +5.5m

    Hurricane Irma (2017) caused devastation in Caribbean islands, leaving thousands homeless

    “For everyone thinking they can ride this storm out, I have news for you: that will be one of the biggest mistakes you can make in your life.”
    Mayor of New Orleans Ray Nagin ahead of Hurricane Gustav, 2008

  • Tropical Storm Chris to strengthen; Beryl weakens to remnants

    July 6 (UPI) — Tropical Storm Chris is predicted to reinforce and remain off the Carolinas’ coast Sunday as Beryl weakened to remnants of a typhoon, according to the National Typhoon Center.

    Chris, third tropical hurricane of the 2018 season, turned into a depression on Friday afternoon.

    Chris used to be desk bound approximately ONE HUNDRED EIGHTY miles south-southeast of Cape Hatteras, N.C. with maximum sustained winds of fifty mph, according to the NHC FIVE p.m. EDT advisory.

    The NHC forecasts the storm to meander off the coast for the next a number of days. They be expecting Chris to develop into a hurricane by means of mid-week with further strengthening forecast afterward.

    Tropical-storm-drive winds extend outward as much as 60 miles from the center.

    No coastal watches or warnings are effect as a result of Chris.

    The remnants of Tropical Typhoon Beryl are moving west-northwestward at 26 mph toward the Lesser Antilles, consistent with the FIVE p.m. EDT post. it is 60 miles northeast of Martinique and 70 miles east-southeast of Dominica.

    A Tropical hurricane watch is in effect for Dominica even as watches for Martinique, St. Martin, St. Barthelemy, Saba, St. Eustatius and St. Maarten, have been discontinued.

    Interests within the Leeward Islands, the Virgin Islands, Puerto Rico, and the Dominican Republic areencouraged to monitor the remnants of Beryl.

    Tropical-storm-pressure winds lengthen outward up to FORTY FIVE miles from the middle.

    Beryl is expected to stay on its present trail, crossing the Lesser Antilles on Sunday and the island chain Sunday night time, and proceeding close to or south of the Virgin Islands and Puerto Rico on Monday. in step with the NHC.

    Forecasters mentioned conditions fairly conducive for regeneration of a tropical cyclone are anticipated as Beryl is forecast to move around the Bahamas and the western Atlantic.

    probabilities of formation are low, close to 0 p.c inside of 48 hours and near 30 percent inside 5 days.

    Tropical typhoon conditions are possible in Dominica and Guadeloupe tonight, the NHC stated.

    Beryl is expected to produce overall rain of two to 3 inches through Tuesday across the Leeward and the Virgin Islands, besides as Puerto Rico.
