What You Should Know About Hurricanes
Posted on 01. Feb, 2010 by Admin in Uncategorized
Hurricanes and cyclones are measured through the use of a system that employs five category descriptions. Those categories are based on the barometric pressure recorded at the storm’s center, wind speeds and storm surge. Hurricanes designated as Category 3 and above are classified as “major hurricanes” by the U.S. National Hurricane Center.
Weather agencies generally use the criteria for defining “sustained winds” as indicated by the World Meteorological Organization. However, the U.S. National Weather Service utilizes a different standard of measurement. But both agencies use approximately the same values when determining central barometric pressure and storm surge.
The 5 categories (in order of their increasing intensity) are:
Category 1 storms are the least severe and will result in limited damage to buildings and other structures. Mobile homes that are not properly anchored can be overturned, however. Poorly affixed roof tiles and shingles may also be blown from houses. There will also be some flooding along coastal regions and damage to piers.
Category 2 storms are intense enough to actually lift a small building (such as a house). Damage may also be inflicted on the windows and doors of larger buildings, as well. But even mobile homes that are properly anchored can suffer significant damage. Considerable damage will be sustained by trees, other forms of vegetation, vehicles and manufactured housing.
Category 3 cyclones are considered major hurricanes. Damage will occur in most buildings constructed of wood and those that do not have good structural support. Mobile homes are usually destroyed by the force of the storm’s winds and other structures can be demolished by flooding. Loss of utilities (electricity) can be experienced and may last for days.
Category 4 hurricanes will greatly affect smaller residences, which may have their entire roofs destroyed or blown away. Gas service stations can suffer irreparable damage to their overhead canopies and other overhanging structures may also be destroyed. Manufactured homes and similar structures will most certainly be leveled. Major flooding and beach erosion will also occur.
Category 5 is the most severe category of tropical cyclones. Small buildings may be completely blown away with major damage to larger buildings, as well. Severe flooding, loss of utilities can affect thousands of residents. Major evacuation of local residents will be indicated in the event of this type of storm. An example of this category of storm is Hurricane Katrina – which reached a category 5 on Sunday August 28, 2005.
