Hurricanes
By definition, a hurricane is fierce rotating storm with an intense centre of low
pressure that only happens in the tropics. In south-east Asia they're known as typhoons
and in the Indian Ocean, cyclones. They cause high winds, huge waves, and heavy
flooding. In 1998, Hurricane Gilbert produced 160 mph winds, killing 318 people, and
devastating Jamaica. A tropical storm can only be classified as a hurricane if it sustains
wind speeds above 73 mph or force 12 on the Beaufort scale. Each year about 50 tropical
storms reach hurricane status. One of the most powerful of all weather systems, hurricanes
are powered by the heat energy released by the condensation of water vapor. However, the
conditions have to be exact for a hurricane to form, with the sea’s surface temperature
being above 26.5
