Hazards - Know your risks

Tropical cyclones are low pressure systems that form over warm tropical waters, generally intensifying over several days, generating severe wind, heavy rain and flooding.  They are powerful weather systems that can cause significant damage to the built and natural environment and can continue for many days, even weeks.  .

The severity of a tropical cyclone is described in terms of categories relating to the strength of the winds ranging from 1 (weakest) to 5 (strongest).

What are the local risks?

Bundaberg has a risk of being impacted by cyclones during the cyclone season that officially runs from November to April. Tropical cyclones can be erratic, and a cyclone of any size can be dangerous. Even when a tropical cyclone weakens to a tropical low, it can bring dangerous conditions.

Warnings

The Bureau of Meteorology (BOM) issues wharings for Tropical Cyclones:

• A Tropical Cyclone Advice - a “notice” that advises the location of a cyclone, its movement and intensity, and identifies areas that could be affected.
• A Cyclone Watch is issued 48 hours before the cyclone is predicted to cross the coast. Updated every six hours, a Cyclone Watch provides information on the location, movement and intensity, and areas that could be affected.
• Cyclone Warnings are issued if winds are expected to affect coastal or island areas within 24 hours. The warning is updated every three hours and then every hour if the cyclone poses a major threat. The warning includes information on location, movement and intensity of the cyclone, areas that are threatened and anticipated rainfall, flooding and storm surge.

BOM also provides a track map for each cyclone showing forecast movement, intensity, watch or warning zones. Cyclone track map can also be found on Bundaberg's Disaster Dashboard.

How to prepare

• Listen for warnings and alerts
• Prepare your emergency plan, emergency kit, evacuation Kit
• Prepare your home
• Prepare your business
• Prepare your pets
• Get to know your neighbours

What to do During

• Stay informed. Tune your battery-operated radio into ABC 100.1 FM
• Listen for warnings and alerts and follow any instructions given.
• Be aware of your shelter and evacuation options
• Stay inside and shelter in the strongest part of the building keeping well clear of windows (eg shelter in the internal hallway or bathroom).
• Turn off and unplug electrical items, external TV/radio aerials and computer modems.
• If the building starts to break up, shelter under a mattress, doona, or a strong table or bench in the strongest part of the building, eg internal room, hallway or built-in wardrobe.
• Beware the calm ‘eye’ of the cyclone. If the wind drops, do not assume the cyclone is over. Violent winds will soon resume from another direction. Wait for the official “all clear”.
