All About Hurricanes

It's the peak of the hurricane season and the Gulf States are anxiously
waiting for the next update from the National Hurricane Center on the
approaching storms. Every year, hurricanes disrupt the lives of millions of
people, forcing them to evacuate their homes for shelters in distant cities.
As a nation, we have learned a lot from Hurricane Katrina. For the millions
affected by the coming storms, it now appears that we have finally learned to
be prepared.
Hurricanes are born in the warm summer waters of the Atlantic and the
Caribbean. Heated by the relentless energy of the sun, the heated waters
spawn a low-pressure center with bands of fierce thunderstorms rotating about
its center. At the surface, moisture-laden winds rushing into the low-
pressure center rise upwards and rise upward, releasing their contents in the
form of tropical rains. When the winds and accompanying thunderstorms reach a
critical mass, an eyewall cloud formation coalesces and another hurricane
begins its relentless path, moving west or northwest towards land.
Ahead of the storm, hurricane watches and warnings are posted throughout the
Gulf States. Warning flags with distinctive red and black markings are
hoisted in the ports and marinas, and every few minutes, a hurricane update
is broadcasted on the local and national news channels. The public is warned
with the latest predictions of the storm's most likely point of making
landfall and people begin to prepare for the worst.
For many people, the worst has come far too often. Category Five hurricanes
with memorable names like Camille, Betsy, Andrew, Dean, Katrina and Rita have
indelibly etched their awesome destructive power in our collective memory.
Those that have previously scoffed at hurricanes, sometimes embarking on a
weekend hurricane party, no longer choose to brave the elements and ride out
the storm. Now, when the word spreads that a new hurricane is threatening
cities like New Orleans, Galveston, Mobile, and Miami, people pay attention.
And, the government, which is responsible for ensuring the safety and
security of the people, is finally prepared to deal with the storm's
aftermath. There is nothing that can be done to divert or destroy the most
awesome natural force on earth, all we can do is clean up, rebuild, and
restore those cities after the hurricane's devastation is complete.
Families living in coastal states and low-lying areas that are prone to
suffer the devastating winds and waters of a hurricane are well advised to
seek shelter well inland, away from the canals, swamps, lakes, marshes and
bayous of the coastal wetlands. If Hurricanes Katrina and Rita taught us
anything, it's that survival can depend upon being as far away from the storm
as possible. You can always return after the storm has passed to rebuild, as
many people are doing today, even though rebuilding can be a struggle.
Hurricanes are going to bring devastation and are sure to disrupt the lives
of millions of people in their path. Over the past few decades, the frequency
and intensity of hurricanes appears to be increasing. Hurricane forecasters
are working hard to develop better technology and prediction models to help
alert a concerned public when and where a hurricane is likely to make
landfall. Once the alert is given, the wise person will pay attention. It is
best to have a family hurricane evacuation plan ready to follow. If not, you
should at least follow the direction to evacuate when given by the local
authorities.
