Warning Systems of a Tropical Cyclone.
The Bureau of Meteorology, a government association, plays a vital and very specific role in monitoring tropical cyclones. There are three warning centres in Australia, Darwin, Perth and Brisbane. These are the most affected cities by cyclones. These centres use advanced technology to monitor and map all the cyclone activity that occurs on the Australian coasts. They also issue a public warning message if there appears to be a disastrous cyclone heading to land.
The Bureau of Meteorology centres have warning systems in place.
These are:
* 3 day outlook statements issued daily by each Tropical Cyclone Warning Centre.
* A tropical cyclone information bulletin is made every 6 hours if a cyclone is present in the Australian region.
* A tropical cyclone watch - advice is given every 6 hours where unsettled conditions are expected in the next 48 hours.
* A tropical cyclone warning is issued every three hours when unsettled conditions are expected within 24 hours.
* A standard emergency signal - an audible signal is sounded on broadcast media in an emergency situation to gain public attention. This is used in an area where a tropical cyclone of category 2 or stronger is expected to affect a community within 12 hours.
