Cyclones & Low Pressure Systems

What is a Cyclone?

A cyclone is a violent tropical storm generated by low-pressure systems, with very strong winds and heavy rain that can cause extensive property damage and injuries to people.

The eye or centre of the cyclone is an area made up of light winds and often clear skies, but this is NOT the end of the cyclone as very destructive winds from the other direction will follow.

Fast Facts

A cyclone watch is issued 48 hours before the cyclone is predicted to cross the coast.
A cyclone warning is issued if winds are expected to affect areas within 24 hours.
When a cyclone warning is issued, it should trigger the activation of a Household Emergency Plan.
Power failures are nearly always involved with cyclones.
The warming of oceans is associated with human-induced climate change and increases the risk of extreme rainfall events.
Tropical cyclone days are projected to decrease in frequency but will likely be of higher intensity where they do occur.
Days with heavy rainfall are expected to become more intense across most areas of Australia due to climate change.
Heatwaves are expected to occur more frequently and with greater intensity in the coming decades.

Severe Tropical Cyclone Risks and Storm Surge Impacts

Severe tropical cyclones can bring significant roofing damage, storm surges, and widespread destruction.
Destructive winds can cause widespread power failures, minimal house damage, and dangerous airborne debris.
Storm tides can cause coastal flooding and erosion, especially during high tide.
Heavy rain and strong winds from weakening cyclones can affect communities throughout all parts of Queensland.
Cyclones can also cause caravans to be destroyed and significant disruption to communities.

Environmental Impact of Cyclones

Cyclones can have a devastating impact on the environment, causing widespread destruction and disruption to ecosystems. The strong winds and storm surges associated with severe tropical cyclones can lead to significant coastal erosion, flooding, and damage to infrastructure. These powerful forces can reshape coastlines, wash away beaches, and destroy natural habitats.

The heavy rain and flooding caused by tropical cyclones can also lead to landslides, soil erosion, and sedimentation in waterways. This not only affects the landscape but also disrupts the natural flow of rivers and streams, impacting aquatic ecosystems. The influx of sediment can smother coral reefs and other marine habitats, leading to long-term ecological damage.

Cyclones can also have a significant impact on wildlife. Many species are displaced or killed by severe weather conditions, and the destruction of habitats can lead to a loss of biodiversity. The disruption of food chains can have cascading effects throughout the ecosystem, affecting both terrestrial and marine life.

In addition to the physical damage, cyclones can lead to the release of pollutants and sediment into waterways, which can have negative impacts on aquatic ecosystems. Contaminated water sources can spread disease and other health problems, posing a risk to both wildlife and human populations.

The destruction of infrastructure and property can also lead to significant economic losses, which can have a lasting impact on communities and the environment. The cost of rebuilding and recovery can strain resources and divert attention from other important environmental initiatives.

To mitigate the environmental impact of cyclones, it is essential to implement measures to reduce greenhouse gas emissions and protect natural habitats. By understanding the environmental impact of cyclones, we can better prepare for and respond to these events, reducing the risk of widespread destruction and promoting a more sustainable future.

Cyclone Preparedness and Safety for Very Destructive Winds

Stay inside and be aware that cyclones are part of living in North Queensland, with most occurring between November and April.
Prepare for a cyclone by staying informed and taking necessary precautions.
Know where to find information about cyclones, including the Burdekin Shire Council Emergency Dashboard and the Bureau of Meteorology.
Take note that not all cyclones make landfall in the area, but it’s essential to be prepared for any eventuality.

Cyclone Warning Systems and Alerts

The Bureau of Meteorology is a great resource for information about cyclones and meteorology.
The Queensland cyclone season officially runs from 1 November to 30 April, but cyclones can occur at other times.
Communities within 50 kilometres of the coastline from Bundaberg to Thursday Island, including the Gulf of Carpentaria, are most susceptible to cyclones.
Stay tuned to local news and weather reports for updates on cyclone warnings and alerts.

Cyclone History and Patterns in Queensland

Tropical cyclones threaten northern Australia every year during the tropical cyclone season, which usually runs from November to April.

On average, the Australian region experiences 11 cyclones a year, although typically only four to five of these cyclones will reach land.

The Bureau of Meteorology tracks tropical cyclone tracks for cyclones that formed or moved through the Eastern region of Queensland, particularly affecting the Queensland coast, from 1970 to 2004.

Eastern Queensland is one of the wetter regions in Australia due to its proximity to the world’s most intensive rainfall band, located in the Western Pacific.

After the Cyclone: Recovery and Support

Queensland Fire and Emergency Services (QFES) may carry out swift water rescues and respond to calls in affected regions.
The cyclone can cause widespread flash flooding, with over 300mm of rain falling in SEQ, and record amounts of rain in the following weeks.
Cyclones can also cause power failure, significant disruption to communities, and extensive property damage.
Recovery efforts may involve clearing debris, repairing damaged infrastructure, and providing support to affected communities.

FAQ

How Many Cyclones Occur in Queensland Each Year?

Cyclone activity in Queensland can fluctuate annually, but on average:

Queensland experiences approximately 4.7 tropical cyclones per year within its Tropical Cyclone Warning Centre Area of responsibility.
Not all cyclones make landfall in Queensland.
Since 1858, there have been 207 recorded impacts from tropical cyclones along the east coast of Queensland.

It’s essential to understand that cyclone frequency is influenced by factors such as the El Niño-Southern Oscillation (ENSO) cycle.

When Was the Last Category 5 Cyclone in Australia?

The most recent system to reach the intensity of a Category 5 severe tropical cyclone in Australia was Cyclone Ilsa, which attained this classification on 13 April 2023 off the coast of Western Australia.

What Are the Months of Cyclone Season in Queensland?

The cyclone season in Queensland generally spans from November to April. Key details about this period include:

The official tropical cyclone season for Australia, including Queensland, is from 1 November to 30 April.
While cyclones can occur outside this timeframe, such instances are rare.
Cyclone activity typically peaks during the summer months (December to February).
La Niña years often see an increase in cyclone activity along the Queensland coast, with three to four times as many cyclones compared to El Niño years.
On average, around 13 cyclones occur in Australia each year.

Residents in cyclone-prone areas must remain prepared throughout the season, regardless of long-range forecasts or average statistics, as even a single cyclone can cause significant impacts.
