2 I Storm Tide Evacuation Guide
Living in a cyclone prone region triggers a need for a heightened level of awareness in our
community...All threats outlined in the Hinchinbrook Shire Local Disaster Management Plan have the potential to, at some time, warrant an evacuation of certain areas within our community. A copy of the Hinchinbrook Shire Local Disaster Management Plan can be found on the Hinchinbrook Shire Council website.
It is the nature of our location, that we could become threatened by tropical cyclones and storm tide inundation, which emphasises the fact that we must be prepared for the cyclone season.
In the event of a cyclone approaching our coastline, an evacuation will only be ordered if it is identified that a storm tide surge is likely to occur in developed areas. For this reason it is important that you familiarise yourself with this guide so you are aware of your zone, if you are required to evacuate in the event of a storm surge.
STORM SURGE...what is it? A storm surge is a rise above the normal ocean level as a result of onshore winds and/or reduced atmospheric pressure. Storm surges accompany a tropical cyclone as it comes ashore. They may also be formed by intense low-pressure systems in non-tropical areas.
The combination of storm surge and normal (astronomical) tide is known as a ‘storm tide’. The most vulnerable time a storm surge can arrive is on top of a high tide, which can inundate areas which could otherwise be safe.
HOW HIGH WILL THE STORM SURGE BE?The height of the storm surge varies depending on several factors being:• The intensity of the cyclone – stronger winds allow for increase in wave height and the sea water is piled
on top of this• The movement of the cyclone – the faster the cyclone crosses the coast, the quicker the surge will build
up and create a more powerful impact when it hits the coastline• The angle the cyclone crosses the coast – a direct hit will encourage a larger surge, but other angles can
lead to local zones of enhanced surge in areas such as narrow inlets and bays• Theprofileoftheseafloor - a shallow coastline allows the surge to increase strength, whereas steep
slopes or fringing reefs can allow the surge to be less• Topography of the area – islands, bays, and headlands can amplify the storm surge
WHAT IF I AM IN A STORM SURGE AREA?• Make arrangements with friends or family who live in a safe place• No friends in a safe place...evacuate to your nearest community evacuation centre• In the event of an evacuation, emergency service workers may doorknock your street to direct you to a
safer place• Ensure all electrical/gas appliances are turned off before you leave• Remember your emergency kit when you leave

A tropical cyclone is defined as a non-frontal low pressure system of synoptic scale developing over warm waters having organised convection and a maximum mean wind speed of 34 knots or greater extending more than half-way around near the centre and persisting for at least six hours.
The severity of a tropical cyclone is described in terms of categories ranging from 1 (weakest) to 5 (strongest) related to the maximum mean wind speed as shown in this table:
Category Maximum Mean Wind
(km/h)
Typical Strongest
Gust (km/h)
Central Pressure
(hPa)
Typical Effects
1 63 - 88 < 125 > 985 • Negligible house damage • Damage to some crops, trees and caravans• Craft may drag moorings
2 89 - 117 125 - 164 985 - 970 • Minor house damage • Significant damage to signs, trees and
caravans• Heavy damage to some crops• Risk of power failure• Small craft may break moorings
3 118 - 159 165 - 224 970 - 955 • Some roof and structural damage• Some caravans destroyed• Power failures likely (e.g. Winifred)
4 160 - 199 225 - 279 955 - 930 • Significant roofing loss and structural damage
• Many caravans destroyed and blown away• Dangerous airborne debris• Widespread power failures (e.g. Tracy,
Olivia) 5 > 200 > 279 < 930 • Extremely dangerous with widespread
destruction (e.g. Vance)

BE PREPARED
• Do you know the evacuation zone in your area?• What is your zone colour?• Is your zone currently under threat?• Do you know your emergency evacuation route?• Have you heard any official advice to evacuate?• Have you packed your emergency evacuation kit?• Is your vehicle full of fuel?
CHECKLIST FOR EVACUATION
PREPARE YOUR EMERGENCY KIT
• Listen to your portable radio constantly• Close up the house - secure doors, board or tape windows and secure
outdoor furniture• Disconnect electrical appliances• Secure your pets in a safe place• Fill water containers• Fuel car and place under cover• Remain indoors with your emergency kit
Be prepared to leave your house in the event of a storm tide evacuation

5Storm Tide Evacuation Guide I
The following evacuation maps are used to inform residents of predicted storm time flooding associated with a tropical cyclone, and to identify areas that may require evacuation.
Three evacuation zones have been identified in the Hinchinbrook region – Red, Orange and Yellow. In the event of a storm tide, authorities will issue an evacuation for the required zones. Evacuation zones were developed using results from Council’s Storm Surge Study of the coastal communities located within the Hinchinbrook Shire Council including Lucinda, Dungeness, Taylors Beach, Forrest Beach and Cassady Beach. Any properties on the coastline, but outside of these areas may still be vulnerable to a storm tide. Residents outside of the study area should consider their individual situation and what actions they may need to take in the event of a storm tide.
It is important that prior and during the disaster you stay tuned to local ABC or commercial radio and TV stations for updates.
EVACUATION ZONEIf an evacuation order is announced for a Red, Orange or Yellow zone, affected residents should move out of the area using the most direct evacuation route.
EVACUATION MAPS
Australian Height Datum (AHD): is the term used to describe the reference level for defining ground levels in Australia. The level of 0.0m AHD is approximately sea level.
HOW TO USE THE STORM TIDE EVACUATION MAPS • Identify your property on the Storm Tide Evacuation Map or locate the evacuation sticker in your electrical
meter box• Remember and record the colour of your zone, so you are aware during a storm tide event• If your property is not coloured it means you are not in a nominated evacuation zone• Identify the primary and/or alternative route so you are prepared in the event of an evacuation
DISCLAIMERStorm Tide Evacuation Zones are based upon geographical data from the National Storm Tide Mapping program. Evacuation Zones are designed to provide an easy to understand method for the public to identify coastal areas that may be affected by storm tides caused by tropical cyclones or severe east coast storms.
Every effort has been made to ensure that the information contained with this Storm Tide Evacuation Guide and Public Information Maps is accurate. However, Hinchinbrook Shire Council does not give any warranty or accept any liability in relation to the content of these maps.
RED ZONE: These properties face the highest risk of coastal flooding from a storm tide. They may experience flooding in areas located up to 2 and 3 metres above AHD.
IF YOU LIVE IN A COASTAL COMMUNITY A STORM
TIDE EVACUATION STICKER IDENTIFYING YOUR ZONE
SHOULD BE LOCATED INSIDE YOUR ELECTRICAL METER BOX
ORANGE ZONE: These properties face a high risk of coastal flooding from a storm tide. They may experience flooding in areas located between 3 and 4 metres above AHD.
YELLOW ZONE:These properties face a moderate risk of coastal flooding form a storm tide. They may experience flooding in areas located between 4 and 6 metres above AHD.
