In 1989 Hurricane
Hugo did an estimated $6 billion dollars worth of damage to a
sparsely populated area, while just a few months back Andrew left
heavily populated Miami with damage estimating anywhere from $7
to $20 billion dollars. America was NOT READY. The southeast United
States awoke to the memory of the great storms of the thirties,
forties, fifties, and sixties that Florida and Georgia once took
as a part of their summer existence. If a storm came, people told
themselves there would be plenty of time to get materials and
board up, get enough bottled water and supplies, and leave the
barrier islands. But more than just remembering, the strength
of these "new" hurricanes was even greater than ever
we knew. No one could have prepared totally for this.
The season when hurricanes
are born starts in June and can continue through November. The
western Caribbean and Gulf of Mexico are the principal areas of
birth, though in early September a few storms originate as far
east as the Cape Verde Islands. On the average, three hurricanes
strike the United States a year, though six out of ten tropical
storms develop into mature hurricanes. Ava, the classically organized
1973 storm, is still the most violent hurricane of record for
the eastern North Pacific area, whereas Camille of 1969 and the
1935 Labor Day storm claim to be the western North Atlantic's
"prizes."
Hurricanes are cyclonic
storms, products of the tropical ocean and atmosphere, powered
by heat from the sea and steered by easterly trade winds and temperate
westerlies. Their single known benefit is a major source of rain
for those continental regions their course reaches. Few hurricanes
mature in the doldrums, but one can begin as a poorly organized
disturbance in an easterly trade wind or a disturbance along the
Intertropical Convergence Zone. It seems to weaken as the young
storm crosses a persistent intruding polar trough. The young storm
stands upon the sea as a whirlwind of awful violence continuing
to build into a tropical storm and further to a full scaled hurricane.
As long as the easterly drift is slow the hurricane may magnify.
More rapid forward motion inhibits intensification in the early
stages of the storm. Fast moving storms soon weaken. Cut off from
their oceanic source of energy, hurricanes break up over land.
The "Bermuda High,"
a semi-permanent persistent high-pressure system, dominates the
North Atlantic in the summer. It is a clockwise spiral of descending
air, lying between the temperate and tropical bands of prevailing
winds, with a surface position centered near Bermuda and the Azores.
When it is south of its normal position, a developed hurricane
is held below it and will move straight inland making the southern
east coast vulnerable. Its movement is controlled by the very
forces which eventually destroy it - the forces that drive it
ashore or over colder water beyond the tropics. Hurricane winds
are produced by differences in atmospheric pressure, or density.
They drop the bottom out of normal pressures.
The hurricane's "eye"
is a unique atmospheric entity where winds diminish to less then
15 knots, but when you penetrate the opposite wall you are abruptly
in the worst of winds again. Tides of 3 to 4 feet above normal
could occur 24 to 36 hours before the "eye" reaches
the coastline causing flooding. If the calm eye of the hurricane
passes through your area, continue to stay indoors. Wind and rain
may stop for as little as minutes or as long as a half hour or
more.
The rising tide and
storm surge pushes water up inland drainage canals preventing
the heavy rainfall from draining off. Most coastal damage caused
by hurricanes is the result of flooding from giant waves driven
by the enormous winds. As a result of intense rainfall over a
prolonged period, the pooling of water in flood prone areas such
as overflowing of lakes and ponds has caused extensive property
damage. Prepare early, locating low lying sections of your community
to avoid, finding the safest route to high grounds, and making
all the necessary preparations to protect your family.
People who live inland
from the coast often feel they will not be affected by an approaching
hurricane. As a hurricane moves inland, its wind forces do weaken
rapidly. But the tons of water the storm picked up over the ocean
will continue to be released causing much inland flooding. Inland
residents, if it appears that flood waters will enter your home,
turn off all electrical and gas service. If water has entered
your home, do not touch electrical switches or appliances to either
turn them off or on. When walking outside, avoid any pools of
water in which a downed power lines is laying. YOU MUST ASSUME
THAT ALL DOWNED POWER LINES ARE ENERGIZED.
Advisory messages are
issued by the National Hurricane Center concerning TROPICAL STORMS
and HURRICANES. These messages give details as to where the tropical
storm or hurricane is located, its intensity, and direction and
the speed of movement. Bulletins are issued to describe weather
disturbances with winds not yet strong enough to be classified
as named storms.
The Tropical Wave or
Disturbance, the first stage of the formation of a hurricane is
a cluster of clouds and/or thunderstorms without an organized
circulation, moving through the tropics. The Tropical Depression
is the second stage, when an organized system of clouds and thunderstorms
within a defined circulation having top winds of less than 39
MPH originates over tropical waters. The Tropical Storm or third
stage is how storms get named. It is an organized system of strong
thunderstorms with a defined circulation and top winds of 39 to
74 MPH blowing counter-clockwise. These can quickly develop into
major hurricanes, intense tropical weather systems with a well
defined circulation and sustaining winds of 74+ MPH. In the northern
hemisphere the winds blow in a counter-clockwise direction around
the center. The size of the storm may range from 60 to 1000 miles
in diameter.
A Gale/Tropical Storm
Warning is the first actual warning issued by authorities in the
area. It is a warning that winds within the range of 39-54 MPH
are in the coastal area. It may be used as the warning for coastal
sections in a hurricane watch. A Tropical Storm Watch says that
conditions are possible for a storm to move into the specified
area of the watch, usually within 36 hours. A Tropical Storm Warning
says that the same conditions are expected in the specified area
of the warning, usually within 24 hours. A Hurricane Watch says
conditions are possible in the specific area of the watch, usually
between 24-48 hours. You should prepare to take immediate action
to protect your property and family in case of a warning being
issued. It indicates that a hurricane is near enough for those
in the covered area need to be ready to take precautionary measures.
A Hurricane Warning says conditions are expected in the specific
area of the watch, usually between 12-24 hours. Complete all storm
preparations and evacuate dangerous or low-lying location as soon
as possible.
The Storm Surge within
a hurricane is the increase in the water level due to the action
of the wind on the ocean surface and the low barometric pressure
of a storm system. It appears as a dome of sea water, up to 20
feet high, that arrives in front of the eye of a hurricane and
can affect as much as 100 miles of coastline. It is the most dangerous
part of the hurricane. Approximately 80% of the damage to structures
along the coast and most hurricane related deaths are caused by
storm surging. The Hurricane's Eye is a deceptively calm area
near the center of the storm, with light winds, warm temperatures,
and the sky more or less clear. DON'T BE FOOLED! The wind will
pick up again--from the opposite direction and often with greater
force. Tornados may descend from the advancing bands of thunder-clouds.
A Tornado Watch is issued when atmospheric conditions are such
that a possibility of tornado development exists. A Tornado Warning
is given when a tornado has been indicated by radar or sighted
in the area.
The National Weather
Station categorizes hurricanes according to their strength. I
will try to identify here the problems expected to occur with
each category of strength. In Category 1 winds of 74 to 95 miles
per hour pound the shore bringing a storm surge of 4 to 5 feet
above normal. This storm will do its own manicuring of shrubbery,
trees, and foliage. It will claim some damage to unanchored mobile
homes and poorly constructed signs but no real damage shows on
other structures at this stage. Low lying coastal roads will be
inundated and some small crafts in exposed anchorage will be torn
from moorings.
Category 2 brings winds
of 96 to 110 miles per hour with a storm surge of 6 to 8 feet
above normal. Noticeable damage will occur to shrubbery and tree
foliage, blowing down the more fragile trees. Major damage can
be expected to exposed mobile homes and to poorly constructed
signs. Roofing materials on buildings will get some damage as
will windows and doors but there should be no major damage to
buildings. Two to four hours before the arrival of the hurricane's
center, rising waters will cut off coastal roads and low lying
escape routes inland. Small crafts in unprotected anchorages will
get torn from moorings. Officials will require evacuation operations
for some shoreline residences and low lying island areas.
Winds of 111 to 130
miles per hour with storm surging of 9 to 12 feet above normal
make up Category 3. Large trees may up root and practically all
poorly constructed signs will lay on the ground or be gone. In
this strength storm small buildings may have some structural damage
and mobile homes can be destroyed. Serious flooding comes to many
smaller structures near the coast, even larger structures will
be damaged by battering waves and floating debris. Low lying escape
routes inland are cut off by rising waters three to five hours
ahead of the "eye." Flat terrains 5 feet or less above
sea level flood inland 8 miles or more. Possibly, officials will
ask for evacuation of low lying residences within several blocks
of the coastal shoreline.
A Category 4 Hurricane's
winds bear down at 131 to 155 miles per hour and surges range
from 13 to 18 feet above normal. Most, if not all signs become
part of the aftermath's rubble and extensive damage comes to roofing
materials, windows and doors, many small residences losing their
roofs. Major damage will occur to lower floors of structures near
shore due to flooding, battering by waves and floating debris.
Flooding can occur in flat terrains of 10 feet or less above sea
level as far as 6 miles away from the coast. Massive evacuation
will be announced for all residences within 500 yards of shore
and for single story residences on low ground within 2 miles of
the shoreline.
Category 5 holds winds
greater than 155 miles per hour and storm surge greater than 18
feet above normal. One can expect to see even large durable trees
on the ground, all signs destroyed, and extensive damage to roofs
of buildings. Complete failure of roofs will be found on many
residences and industrial buildings with very severe and extensive
shattering of glass in windows and doors. Some complete buildings
will be destroyed, small buildings overturned or blown away. Mobile
homes can expect complete destruction. Major damage will come
to the lower floors of all structures less than 15 feet above
sea level within 500 yards of shore. Massive evacuation will come
to residential areas on low ground within 5 to 10 miles of shore.
We need to take seriously
the wise words of warning the National Hurricane Center give to
the coastal population about preparing in June not in late August
or early September. Once an issue of "hurricane watch"
has gone out the following jobs should be considered. Fill your
car's gasoline tank. Check the water, oil, and battery. Check
your flashlights and batteries and have extras on hand. Stay tuned
to the radio and television for advisories and information. Obtain
and mark clean containers for storing drinking water. Refill prescription
drugs and obtain any special medication.Outline emergency plans
with your household. Make arrangements for your pets. They will
not be allowed in the shelter. Tie down sheds and other large
items anchoring buried in the ground. Inspect and clear yards
and outside courtyards carefully removing loose objects including
garbage cans, bicycles, furniture, removable bar-b-ques, and potted
plants. Trim trees and shrubs. Document or video your belongings
for insurance purposes. Take to bank safe or with you a complete
back up disk or tape of your computer hard drive (if you have
a computer).
The Weather Center
will change the directive from "watch" to "warning"
as the hurricane approaches. At that time be sure to
board your home protecting
all windows. Leave a northern exposed window cracked to equalize
pressure so your house won't expand. Turn freezer and refrigerator
to coldest temperature to insure food inside will last if electricity
goes. If not opened the freezer will keep cold for two days. You
can help insure coldness by adding extra insulation with quilts
and blankets. DO NOT COVER THE AIR VENTS OR CONDENSER. Gather
things you need to take to a shelter or to the home of a friend.
Put together supplies if you plan to stay home. An interior room
or a room without windows is usually the safest place to sit the
hurricane out. Many of the things you own are considered by you
to be irreplaceable. These items should be elevated above floor
level before you evacuate. Use flashlights instead of candles
or kerosine lamps as a gust of wind through a door or window could
start a blaze and the fire department may not be available to
respond. Prepare to evacuate if ordered to do so.
If evacuation is announced,
here are some safety rules for those of you assigned notice which
will help you go safely on your journey.
1. Before making last
minute preparations be sure you have time. Don't wait until the
last minute to leave, hoping to save your possessions. SAVE YOUR
LIFE.
2. Move quickly and
calmly. In a flash flood your automobile may not be your safest
and quickest form of transportation. If your nearest shelter is
on a hill, walking up the hill to shelter might be better.
3. Keep your radio
turned on and located where you can hear it.
4. Know where you are
going before you leave. Searching for an unknown shelter could
be hazardous. If you don't know the location of public shelters,
listen to your radio for instructions.
5. If limited in time
to evacuate, take only family medicines, blankets, and a battery-operated
radio.
6. If there is time
turn off utilities and open basement windows to let water in and
equalize pressure.
7. Lock your home.
8. As you drive, listen
to radio for evacuation notices and watch for washed out bridges,
undermined roads, landslides, downed power lines, etc.
9. Bridges will not
be raised at a time which would block escape routes during hurricane
evacuation so escaping boaters move out early.
The aftermath of a
hurricane holds its own dangers. Don't just run outside ready
to haul away rubble. There are considerations to make and dangers
to watch for. Remain indoors until an "all clear" announcement
is given. Listen to the radio for instructions. If your home has
structural damage, do not go in until it is checked by officials.
Report individual trouble with utilities only after service has
been restored in your neighborhood. The utility companies have
plans to restore service as quickly as possible. The health department
may order a boil water order immediately after the hurricane passes.
It would remain in effect for at least 72 hours. Refrigerated
and frozen foods can last up to three days without power, but
check for spoilage before using any foods from the refrigerator.
Be careful with open flames. Never use gas grills inside your
house. There is danger of carbon monoxide poisoning. Immediately
report property damage to your insurance agent. Make emergency
repairs to prevent further damage to your home or contents. Include
boarding up damaged windows and holes in your roof. Beware of
fly-by-night repair businesses. If damages require you to leave
your home, secure your property and leave a forwarding phone number
and address where you can be reached. When re-entering your home
be careful of loose or dangling power lines. Do not light matches
or use lighters if gas is used in your home because there may
be leaky gas lines. Be careful where you walk or drive because
poisonous snakes and insects may be present after flooding. Insurance
Companies will handle the claims for worst damages first. BE PATIENT.
Here are some general
tips on care of property and your person before and after the
storm. The best protection for your windows and glass sliding
doors is either regular window shutters or metal paneling. Plywood
or Masonite placed over the entire window opened with at least
4-6" overlap also provides good protection. Tape will only
reduced the amount of glass flying if the window is shattered
but it will do little, if any, good in 120 MPH winds. Remove it
immediately after storm passes as sun will bake it on.
One of your most crucial
needs is a supply of safe water. Every person in your family needs
at least 2 quarts of water or other liquids daily. You also need
pure water for preparing food, brushing teeth, and keeping clean.
Soft drinks and juices substitute for water, ice works well, and
having bottled water is a real benefit, but you should fill bathtubs
and sinks with water ahead of time also. If you have amply bottled
water and drink supplies, try to use bathtub/sink water for toilets
and washing as much as possible to save the other supplies for
cooking, drinking and brushing teeth.
Strain the water through
a paper towel or several thicknesses of clean cloth to remove
dirt. If possible, after the solid particles have been removed,
boil water for 10 minutes, or add a water purifying agent (liquid
bleach, water-purifying tablets, 2% tincture of iodine).
Don't drain your pool
unless you want to watch your pool pop wrong side out. Lower the
water level slightly but no more than a foot or two. More than
that will have the same effect as draining it.
To protect roof mounted
turbines from damage, they should be removed prior to arrival
of strong winds. Metal covers are available to place over the
open stand pipe after removing the turbine.
Following floods, storms,
and hurricanes, snakes and rodents are often forced into places
where they are not usually found. Know how to identify poisonous
snakes common to your area. Keep a heavy stick or some other weapon
handy. Search the premises thoroughly. Be alert for snakes in
and around homes, barns, outbuildings, stalled automobiles, piles
of debris, trash or any type of rubble. In clean-up operations
wear heavy leather or rubber high-topped boots, and heavy gloves.
To control snakes remove snakes' food supply by eliminating rats
and mice from area. Get rid of debris, lumber piles, and trash
piles and block openings where snakes might enter a building.
Rats and other rodents
may move into building to escape flood-waters. Rats can carry
disease and small vermin. They should be eliminated as soon as
possible. Because of the danger of rat infestation, use the same
caution as with snakes when entering flooded buildings. Carry
a solid club and a flashlight. Inspect likely hiding places for
rats. Check closets,
furniture, drawers,
mattresses, appliances, stacks of clothing and papers, dark corners,
attics and basements. Be extremely careful approaching rat. A
starving rat can be dangerous. Poison rats that have not been
eliminated by clubbing or trapping. After infestation is controlled
clean up rat harboring places. Remove food sources. If bitten
take the rat to your local health authorities or a veterinarian.
The animal should be checked for rabies.
At the time a hurricane
approaches it is already too late to make list of things you'll
need before sitting it out or evacuating. Prepare and have handy
those lists early in the season. Here are some examples.

Boaters have a whole
new set of responsibilities during these storms. A boat owner/operator
may be held responsible for damages caused by his vessel during
a natural disaster. Hurricane moorings should be located and permission
obtained well in advance. A Practice run should be made to check
accessibility, depth of water, bridges, and locating aids and/or
obstructions to navigation and objects to secure lines to or drop
anchor. Record and keep with you the vessel's registration number,
description, and location where secured. Inform your local marine
patrol or police of your secured vessel's identification and location.
Make plans with someone knowledgeable to care for your boat should
the need rise if vacationing or out of town during hurricane season.
Check your contract or policy with your marina. Know your responsibilities
and liabilities with your boat and marina.
The equipment for your
boat needs its own attention. Lines of adequate length (preferably
nylon) should be available. Have more than you think you'll need.
Have available chafing gear (old rags or old water hose if large
enough) for all lines to protect them from wear at contact points.
Secure fenders of adequate size and strength (old tires) to protect
it from other boats, sea walls, etc. Collect radio equipment for
receiving weather information and communication. Anchors should
be oversized (25 lbs+) and use all methods to improve holding
power. Fuel tanks should be kept full if possible during hurricane
season. Keep batteries fully charged and have an extra on hand.
bilge pumps keep in working order.
Make sure to secure
your boat. Prepare in advance the things needed to secure your
vessel. Assemble together equipment and supplies. Large trees
may be used to fasten your vessel. Ensure that they are alive
and have a good root system. Be sure to check the strength of
the things you tie to. Tides can reach heights of 10 to 20 feet
above normal. Take care to consider this. Wind direction reverses
itself in a hurricane. Secure your boat from all directions. Seal
all openings to make boat watertight. Strip boat of all moveable
equipment such as canvas, sails, dinghies, radios, and cushions.
Lash down what you can't remove. Open drains before securing if
you leave your boat on a davit.
If you secure your
boat on a trailer, place wooden blocks between the frame and the
axle inside each wheel. Let 1/2 the air out of the tires. Fill
the boat 1/3 with water. Tie your boat and trailer securely to
a strong object such as a telephone pole. If boat can't be secured
in this manner, removed from the trailer and partially fill with
water to reduce its vulnerability. Tie down trailer.
At the hurricane warning
leave early for safe harbor. Remember, there may not be room for
your boat at the last minute. Do not stay aboard. Even small hurricanes
pack 75 mile winds with gusts of 110 miles. Seek safe shelter.
Do not attempt to leave the area by boat unless you have a fast
boat and are prepared to travel long distances in rough weather.
After the hurricane
check for damage to your boat and equipment before moving. When
proceeding to home port, watch carefully for obstructions and
loose debris in water. Markers and other aids may be missing.
A mobile home is not
safe in hurricane conditions, no matter how securely it's affixed
to the ground. If you live in a mobile home, no matter where located,
you must evacuate prior to the arrival of a hurricane.
When a tropical storm
or hurricane approaches your area, take all the precautions to
secure your home and leave for a shelter. DON'T ride out a hurricane
in a mobile home.
Stay with friends or
relatives as long as they live in a home of substantial construction
away from flood-prone areas. Your second choice is one of the
American Red Cross hurricane shelters. If your park has their
own recreation facility and clubhouse the clubhouse may be a source
of shelter.
Hurricanes can create
devastation--people left homeless and jobless, with complete businesses
wiped out and homes leveled. There can be long periods where homes
still in tact are without services and people get sick, even die
from lack of clean water and poor food supplies. In the event
of a major hurricane don't be fooled, be prepared for the worst.
If you benefit from less, rejoice by helping where you can. This
is my contribution
