Great post www - you would think that this sort of cyclone information would be taught in schools in Cyclone Prone areas these days. Having lived through a couple of doosies and had numerous near misses over the years, you get to know a little bit about TC's, however, as each one has a mind all of its own - this sort of information should be broadcast along with the warnings.
A little bit of education never hurt anyone!

One measure of the size of a tropical cyclone is determined by measuring the distance from its center of circulation to its outermost closed isobar, also known as its ROCI. If the radius is less than two degrees of latitude or 222 kilometers (138 mi), then the cyclone is "very small" or a "midget". A radius between 3 and 6 latitude degrees or 333 kilometers (207 mi) to 670 kilometres (420 mi) are considered "average-sized". "Very large" tropical cyclones have a radius of greater than 8 degrees or 888 kilometres (552 mi).[10] Use of this measure has objectively determined that tropical cyclones in the northwest Pacific Ocean are the largest on earth on average, with Atlantic tropical cyclones roughly half their size.[11] Other methods of determining a tropical cyclone's size include measuring the radius of gale force winds and measuring the radius at which its relative vorticity field decreases to 1×10−5 s−1 from its center.[12][13] kilometres
1degree of latitude = 110.649klm ROCI Type Less than 2 degrees latitude Very small/midget 2 to 3 degrees of latitude Small 3 to 6 degrees of latitude Medium/Average 6 to 8 degrees of latitude Large anti-dwarf Over 8 degrees of latitude Very large

I was advised by a builder to put a mattress against the inside of the garage door, then park the car next to it. Has anybody heard of this before?

Dawn I have heard that you put your wheelie bins between your car and the roller door. So when the roller door blows in it wont damage your car as much. Thanks so much. I think the wheelie bins sound better.

Will keep the wheelie bins from becoming missiles, too- as they'll be out of the way! Double advantage!

I have just been checking the storm track and have noticed it is on track for the center of the eye to be just 100 kilometers out to sea at full tide at Cairns at 9.30 in the morning. High tide without the cyclone would be 2.8 meters.

Cyclone Tip:
Having been through a handful of cyclones in my short life...Winifred, Althea, Peter... I would recommend people put pool furniture, trampolines and other potential missiles in their swimming pools. The pool will prevent those items relocating to parts unknown and will need to be cleared of debris after the event anyway.

Cyclone Tip:
The story about opening a window on the leeward (downwind) side of your house is an old wives' tale. It basically sets up a Bernoulli vacuum in your house, reducing atmospheric pressure inside the structure as wind rushes past and sucks air out. That increases downforce on your ceiling and roof but will also increase vacuum loading on the inside of the windward walls of the structure, increasing the likelihood they will fail.
Close all windows and doors and rely upon the structural integrity of the building.

Cyclone Tip:
Everyone hears this one but it's worth repeating: Bathrooms, toilets and hallways are the strongest structural areas of the house... especially if they have small windows and strong doors. Shelter within those areas and remember that even if the roof comes off they are still safer than being outside.
NB Large concrete block walls are prone to collapse in very high winds. An example of such a wall is usually found on the side of a garage, where a 6-8 metre span of brick wall may be subject to high winds.

Cyclone Tip:
Clean your bathtub out with dishwashing liquid and rinse well. Then insert the plug and fill with fresh water and cover with a large sheet of plastic. It may be your best source of fresh water in the aftermath of the storm. Utilities may take up to a week to reconnect water services.

I need some answers please Weatherzone.
The highest wind gust recorded was at Lucinda point and reached 180km/hr. Lucinda is 40km south of Cardwell that lost 200 homes. Carwell is clearly in the centre of the storm as Tully and Mission Beach only lost 20 homes each. So if Lucinda point recorded 180km/hr how come reporters are referring to 290 km/hr winds??
Secondly - why has Weatherzone removed the Lucinda Point wind record from it's site and replaced it with Townsville airport?
