Cyclone Preparedness

CYCLONE PREPAREDNESS

Before the storm arrive
Assemble a Disaster Supplies Kit Including the Following Items :
1. First aid kit and essential medications.
2. Canned food and can opener.
3. At least three gallons of water per person.
4. Protective clothing, rainwear, and bedding or sleeping bags.
5. Battery-powered radio, flashlight, and extra batteries.
6. Special items for infants, elderly, or disabled family members.

Prepare a Personal Evacuation Plan
1. Identify ahead of time where you could go if you are told to evacuate. Choose several places--a friend's home, hotel, or a sheltered place.
2. Keep handy the telephone numbers of these places as well as a road map of your locality. You may need to take alternative or unfamiliar routes if major roads are closed or clogged.
3. Listen to local radio or TV stations for evacuation  instructions. If advised to evacuate, do so immediately. Take these items with you when evacuating:
a. Prescription medications and medical supplies;
b. Bedding and clothing, including sleeping bags and pillows
c. Bottled water, battery-operated radio and extra batteries, first aid kit, flashlight
d. Car keys and maps
e. Documents, including driver’s license, proof of residence, insurance policies, wills, deeds, birth and marriage certificates,tax records, etc.

You should evacuate under the following conditions:

 1. If you are directed by local authorities or through official PDO communication. Be sure to follow their instructions
  2. If you live or work in a temporary structure—such shelters are particularly hazardous during cyclones no matter how well fastened to the ground.

During a Cyclone You should:
1. Listen to the radio or TV for information.
2. Secure your home, close shutters, and secure outdoor objects or bring them indoors
3. Turn the refrigerator thermostat to its coldest setting and keep its doors closed.
4. Turn off propane tanks. Avoid using the phone,except for serious emergencies.
5. Secure your boat if time permits.
6. Ensure a supply of water for sanitary purposes  such as cleaning and flushing toilets. Fill the bathtub and other large containers with water.
7. STAY OUT OF AND AWAY FROM WADIS.
Cyclones generate enormous amounts of rain in very short times. The only place for the water to go is down the wadis; they will fill quickly, and flow ferociously fast. If you come upon a flooded road, turn around and go another way. If you are caught on a flooded road and waters are rising rapidly around you, get out of the car and climb to higher ground.

8. Do not go out “sightseeing”If the storm suddenly seems to abate. Be aware that the calm "eye" is deceptive; the storm is not over. The worst part of the storm will happen once the eye passes over and the winds blow from the opposite direction. Trees, shrubs, buildings, and other objects damaged by the first winds can be broken or destroyed by the second winds.

9. You will probably lose electrical power. That is almost a given. If this  happens:

                        a. Only use a flashlight for emergency lighting.
                        Never use candles!
                        b. Turn off electrical equipment you were using
                        when the power went out.
                        c. Avoid opening the refrigerator and freezer.
                        d. Do not run a generator inside a home.
                        e. Assemble essential supplies, including
                        i. Flashlight
                        ii. Batteries
            iii. Portable radio
                        iv. At least one gallon of water
                        v. A small supply of food.
                        vi. Due to the extreme risk of fire, do not us  candles during a power outage.

If you feel you are in danger:
Go to a safe room (windowlessroom near the centre of the house). If you do not have one, follow these guidelines:
1. Stay indoors during the cyclone and away from windows and glass doors.
2. Close all interior doors—secure and brace external doors.
3. Keep curtains and blinds closed. Do not be fooled if there is a lull; it could be the eye of the storm – winds will pick up again.
4. Take refuge in a small interior room, closet, or hallway on the lowest level.

After  a Cyclone:
1. Listen to the media for regular updates.
2. Inspect your home for water/wind damagevbefore restoring electrical power.
3. Do not make unnecessary demands on the emergency services.
4. Inspect your vehicles for flood/impact damage; especially the undercarriage/brakes if your vehicle experience high water.
5. BEWARE of displaced animals. Wadi dogs, cats, snakes and many potentially nasty
insects will have had their living areas flood. They may seek refuge in your home, carport or even auto. Be very careful assessing storm damage and look carefully before lifting any storm debris; animals may lurk there.
6. Do not touch wet switches, and beware of fallen power lines, treat them as if they are live
7. Do not drink water that could be contaminated.
8. Stay at home, resist the urge to go sightseeing.
9. Use common sense.

What is Cyclone ?

What is a Cyclone?

Cyclones are huge revolving storms caused by winds blowing around a central area of low atmospheric pressure. In the northern hemisphere, cyclones are called hurricanes or typhoons and their winds blow in an anti-clockwise circle. In the southern hemisphere, these tropical storms are known as cyclones, whose winds blow in a clockwise circle.

How do Cyclones occur?

Cyclones develop over warm seas near the Equator. Air heated by the sun rises very swiftly, which creates areas of very low pressure. As the warm air rises, it becomes loaded with moisture which condenses into massive thunderclouds. Cool air rushes in to fill the void that is left, but because of the constant turning of the Earth on its axis, the air is bent inwards and then spirals upwards with great force. The swirling winds rotate faster and faster, forming a huge circle which can be up to 2,000 km across. At the centre of the storm is a calm, cloudless area called the eye, where there is no rain, and the winds are fairly light.

As the cyclone builds up it begins to move. It is sustained by a steady flow of warm, moist air. The strongest winds and heaviest rains are found in the towering clouds which merge into a wall about 20-30 km from the storm's centre. Winds around the eye can reach speeds of up to 200 km/h, and a fully developed cyclone pumps out about two million tonnes of air per second. This results in more rain being released in a day than falls in a year in a city like London.

When and where do Cyclones occur?

Cyclones begin in tropical regions, such as northern Australia, South-East Asia and many Pacific islands. They sometimes drift into the temperate coastal areas, threatening more heavily populated regions to the South. Northern Australia has about four or five tropical cyclones every year during the summertime wet season. For a cyclone to develop, the sea surface must have a temperature of at least 26ÂșC.

Why do Cyclones occur?

When warm air rises from the seas and condenses into clouds, massive amounts of heat are released. The result of this mixture of heat and moisture is often a collection of thunderstorms, from which a tropical storm can develop.
The trigger for most Atlantic hurricanes is an easterly wave, a band of low pressure moving westwards, which may have begun as an African thunderstorm. Vigorous thunderstorms and high winds combine to create a cluster of thunderstorms which can become the seedling for a tropical storm.
Typhoons in the Far East and Cyclones in the Indian Ocean often develop from a thunderstorm in the equatorial trough. During the hurricane season, the Coriolis effect of the Earth's rotation starts the winds in the thunderstorm spinning in a circular motion.

Cyclone Danger

Cyclones create several dangers for people living around tropical areas. The most destructive force of a cyclone comes from the fierce winds. These winds are strong enough to easily topple fences, sheds, trees, power poles and caravans, while hurling helpless people through the air. Many people are killed when the cyclone's winds cause buildings to collapse and houses to completely blow away.
A cyclone typically churns up the sea, causing giant waves and surges of water known as storm surges. The water of a storm surge rushes inland with deadly power, flooding low-lying coastal areas. The rains from cyclones are also heavy enough to cause serious flooding, especially along river areas.

Long after a cyclone has passed, road and rail transport can still be blocked by floodwaters. Safe lighting of homes and proper refrigeration of food may be impossible because of failing power supplies. Water often becomes contaminated from dead animals or rotting food, and people are threatened with diseases like gastroenteritis.
