is a tropical cyclone and what to do to stay safe?
Wet Season in the tropics we are all threatened by destructive
cyclones that can hit the coast.
Due to the direction in which the Earth rotates, in the big picture
they move from east to west, and so they often hit the
Locally, though, they
can change direction and move in any direction
for a little while.
It is important to be
aware of what they are and how to protect your
life and your property.
What Is a Tropical Cyclone?
A tropical cyclone is a powerful, rotating wind system that
forms above warm
ocean waters during the hottest time of the year, and has destructive
winds rotating around a calm eye in
It doesn't mean much until it
hits the coast and threatens life and property.

system, which is always the start of a cyclone, will become a cyclone
once its winds reach 100 km/h.
Cat one is 100-124 km/h, cat two is 125-164 km/h, cat three is
165-224km/h, cat four is 225-279 km/h and cat five is more than 280
A tropical cyclone and a hurricane are basically the same thing.
small differences include that being in the Northern Hemisphere
hurricanes have the opposite wind direction; and that due to
the differences in categorising the power of a
hurricane equals a 'severe' tropical cyclone.
However a cyclone and a tornado are two entirely different things.
While a tornado also is a violent system of rotating winds just like a
cyclone, a tornado is smaller (area-wise) and usually a lot stronger;
as opposed to tropical cyclones it forms above the land, and it comes from thunderstorms.
That means they form in
Australia, and during the warmer part of the year. The season is November to
April (included), and yes you can prepare before the season starts.
Advice - Watch and Warnings
If a cyclone is likely to affect an area within 48 hours, that area
gets what is
updated every six hours and gives
information about the cyclone's location, movement and strength.
hours is left, you get the more serious cyclone
When you get the cyclone warnings it is the high time to clean your
yard, tape your windows, secure your car, boat, caravan, and important documents. If you are travelling
and a cyclone is coming,
out of the area, or discuss what to do with your accommodation provider.
Evacuation Procedures Within
the last 24 hours you
also have to decide whether you stay or leave.
If you stay at home you
stay in the safest room, but if you don't feel safe at home and
particularly if you live in flooding or storm
surge area, you should
evacuate either to a different place, or to a cyclone shelter.
Whether you stay at home or evacuate, you also prepare a cyclone kit.
If you stay at home, it means having the things prepared and handy, if
you evacuate you bring the kit with you, and the contents can differ
depending on whether you evacuate to a cyclone shelter or stay in
accommodation or at friends and relatives.
It can be
dangerous, and there are also things
that you will
have to prepare. In the early aftermath you have to watch out for
hanging branches and power lines, then you have the post cyclone
cleaning, and most likely you have no power and no water supply.

preparation is to decide
whether you stay at home or leave the place.
You are usually only ordered to leave if you risk flooding or storm
surge, but if you don't feel safe at home, of course it is your choice
whether to leave.
It is recommended you go to friends and relatives if possible, but if
those are too far you can go to your closest cyclone shelter.

Procedures - Cyclone Shelter
Make sure a cyclone shelter is
activated or you may get there and it is closed. They do
announce officially if they activate one.
Make your mind up early, and go
early enough to make sure you get in.
Cyclone shelters don't have endless space, and they can close early - once the winds reach 100km/h
- to avoid the situation where people are out there in too strong winds.
There is only so much parking space, so use one car per family.
Cyclone shelters are not
the most comfortable places to sleep. If you do have friends
and relatives close enough consider them - it will be more
fun and more comfortable.

And all that said I am talking about the Cooktown
shelter - some
evacuation procedures in some other shelters may be different.

the impact for you as a traveller?
If there is a tropical cyclone up north, will north Queensland close down?
And how long will it
take before you
will be able to travel up here? Well a
tropical cyclone has two
main kinds of impact.
Tropical Cyclone Impact - Wind
The first is
the wind destruction
and damage. That mostly happens with high category cyclones, but if
it's a remote area, where the buildings are not always cyclone proof,
low category cyclones can cause damage too.
That damage can be devastating for locals, but does not make much difference for
you as a
traveller (provided, of course, that you are in a safe

water, due to a low pressure system - often a tropical
Cyclone Impact - Storm Surge
surge happens because out on the ocean the low pressure system and the
strong winds are pushing on the surface of the ocean, so as the cyclone
is coming towards the coast, the
rise can come to the coast and the water can come over low lying areas.
like a tsunami, the
water can move in quickly and
cause serious damage to the coastal buildings. All tropical cyclones
cause a storm surge, but not all are dangerous.
Obviously the stronger
the cyclone winds, the higher and more damaging
can be the surge.
The quicker the cyclone
moves to the coast, the higher is the surge.
And if it coincides with high
tide that also makes it a lot worse.
And some other local
factors that affect it
include the shape of the sea floor, the shape of the headlands and
bays, and the angle at which the tropical cyclone is approaching the

start during the cyclone, sometimes even before, and can last for anything from a few days
week, sometimes two, but that's about the most.
Will those rains cause floods in north Queensland?
Well, while the rains
locally they can. The river and creek waters do go up, some people can
get flooded in if
they are living on low laying land.
But what is the difference from south eastern Queensland - famously the
ground for the 2010-11 floods (also the 2013 floods brought by Cyclone
- is that our floods
don't last much
longer than the rains.
We are on higher grounds, our ground is not as flood prone.
Once the cyclone rains
are gone, the
creeks and rivers go down quite quickly, and pretty soon the cyclone
impact is gone.
Queensland does not shut down,
after a week or two the life goes on as ever before :-)
Rain and Cyclone Impact in
Is Cape York any different?
Well only when it comes to the fact that the roads are unsealed and
obviously get more boggy and slippery.
When it comes to how
rivers and creeks go down, it can be the matter of hours after the rain
stops (depending on how long and heavy it was).
So even if Cyclone Zane
did hit the
coast, its impact would not have
lasted to June or July - not even the second half of May in fact (2013).
