Hurricane information

Hurricane can produce violent winds, incredible waves, torrential rains and floods. In other regions of the world, these types of storms have different names. Hurricanes need warm tropical oceans, moisture and light winds above them. The whole hurricane naming process, like any international enterprise, is a bit confusing. Depending on the region of the world that the big storm originates, it may or may not be called a "hurricane", after all. The generic name for a hurricane is tropical cyclone. These storms are called typhoons when they occur in the western Pacific Ocean, and cyclones in the Indian and southern Pacific Oceans. A tropical storm becomes a hurricane when winds reach 74 mph.
In 1953 the National Hurricane Center began to give short, easy to remember names to identify each hurricane they were tracking. They made lists of names to give to hurricanes. The lists are now maintained and updated by an international committee of the World Meteorological Organization. In 1979, men's names were added to the lists and now alternate with the women's names.
The centre of a hurricane is known as the eye of the storm. When seen from above, this eye is in the middle of the hurricane and looks cloud free. It is clear because the air has a downward, and since clouds require rising air to form, the eye of the hurricane has no clouds. The same thing happens to clouds as they are pulled by the low pressure of the eye into the centre of the hurricane. When looking at a hurricane from above, you will see this area called the eye wall. It is the broad band immediately surrounding the eye and is where the storm is the worst. Feeder bands are the long zones of clouds, showers, and thundershower activity that get their moisture over warm water. They are what give energy to a hurricane.
There are five categories of hurricane called the Saffir-Simpson Hurricane Scale.
- Category 1 - Winds between 74 and 95 miles per hour.
- Category 2 - Winds between 96 and 110 miles per hour.
- Category 3 - Winds between 111 and 130 miles per hour.
- Category 4 - Winds between 131 and 155 miles per hour.
- Category 5 - Winds above 155 miles per hour.
Stay safe this hurricane season. If you are prepared, and with some common sense, you can insure the safety of the most precious possessions you have, your life and the lives of your loved ones.
