This enables efficient detection and fast assessment of cyclone threats followed by speedy transmission of warning messages to threatened areas. Reports from Co-operative Observers in the area help to keep the TCWC right up to date with actual conditions. The Warning System is supported by an ongoing research and development program which is directed at implementing the latest scientific and technical advances. Latest computer techniques are being used to develop improved models for predicting the development and movement of tropical cyclones and these will result in even better tropical cyclone forecasts. These winds can cause extensive property damage and cause airborne debris to become potentially lethal missiles.
Cyclones also produce flood rains which can cause further damage and death by drowning.
Another marine phenomenon which can cause inundation of low lying coastal areas is the storm surge. This is a raised dome of water about 60 to 80 km across and typically about 2 to 5m higher than the normal tide level. If the surge occurs at the same time as a high tide then the area inundated may be quite extensive. The general name given to cyclone Watch and Warning messages is an Advice or Tropical Cyclone Advice. The TCWC issues these messages and liaises with the police, State and Territory Emergency Services and the media.
