HURRICANES

 

Among the various natural disasters that can affect our lives one of the most damaging and deadly events that occur is the hurricane. When hurricanes move ashore, they bring with them a storm surge of ocean water along the coastline, high winds, tornadoes, and both torrential rains and flooding. An excellent example of this can be Hurricane Katrina, first Category 5 hurricane of the 2005 Atlantic hurricane season.

During hurricane Katrina, homes, businesses, roads and bridges were damaged or destroyed by high winds and/or high waves. Debris from the high winds damaged property. Roads and bridges were washed away by flash flooding or blocked by debris. In this particularly large storm, the force of the wind alone caused tremendous devastation. Trees and power lines toppled and weak homes and buildings crumbled. These losses were not just limited to the coastline ­ damage extended hundreds of miles inland.

The birth of a hurricane requires at least three conditions. First, the ocean waters must be warm enough at the surface to put enough heat and moisture into the overlying atmosphere. Second, atmospheric moisture from seawater evaporation must combine with that heat and energy to form the powerful engine needed to propel a hurricane. Third, a wind pattern must be near the ocean surface to spiral air inward: the beginnings of a hurricane! Hurricanes and their potential for destruction are rated using a scale from 1 to 5 called the Saffir­Simpson scale. A Category 1 hurricane is the least destructive and a Category 5 hurricane is the most destructive. The rankings are not absolute in terms of effects. Lower-category storms can inflict greater damage than higher-category storms, depending on factors such as local terrain and total rainfall. In fact, tropical systems of less than hurricane strength can produce significant damage and human casualties, especially from flooding and landslides.

Hurricanes are named to provide ease of communication between forecasters and the general public regarding forecast, watches and warnings. Since the storms can often last a week or longer and that more than one can be occurring in the same area at the same time, names can reduce the confusion about what storm is being described.
