Eastern Australia is bracing for important impacts as Cyclone Alfred approaches. The rare storm is expected to make landfall near brisbane, bringing dangerous winds and severe flooding to Queensland and surrounding areas.
Thousands have been advised to evacuate as the slow-moving tropical storm, named Alfred, poses a substantial threat to coastal communities. Schools are closed, and public transport has been suspended as residents prepare for the cyclone’s arrival.
Rare Cyclone Expected to Bring Catastrophic Conditions
On average, Australia experiences four cyclones each year. Though,Cyclone Alfred is unique due to it’s projected path and potential for prolonged rainfall.
Early wind and rain have already begun impacting eastern Australia. Desperate residents,facing sandbag shortages,have resorted to buying potting mix as a substitute.
Landfall Expected Near Brisbane
Tropical Cyclone Alfred is forecast to cross the Queensland state coast somewhere between the Sunshine Coast region and the city of Brisbane. The exact location and timing of landfall remain critical concerns for emergency services and local authorities.
The Uniqueness of Cyclone Alfred
Communities in southeast Queensland and northern New South Wales have been bracing for the impact of Cyclone Alfred for several days as the slow moving storm system sits off the Australian east coast.
In many ways, most people will not have seen a tropical cyclone like Tropical Cyclone Alfred. That might not be because of top wind gusts or rainfall amounts — but more for the combination of factors.
The big difference of course is the major right turn the cyclone took late last week.
In most cases, tropical cyclones move southeast out of the tropics and gradually dissipate as they reach the cooler waters of higher latitudes and engage in the upper level westerlies.
The sharp right turn that alfred took is not solely unique but our warming planet could be playing a part in this too. It is indeed known that the planetary warming has caused the jet stream to become more erratic and wobbly in recent years.
The cause of the westward drift of Cyclone Alfred was mainly down to the position of the jet stream — the meandering river of wind in the higher atmosphere.
There are several others but the one we’ll talk about is the sub-tropical jet stream.
Late last week, the system that moved up across New Zealand and the Tasman Sea was steered north by a bend in the upper jet stream winds.An upper trough.
Residual Upper Energy
At the top end of it some residual upper energy lingered across the north of Australia. This clockwise swirling band of wind in the higher atmosphere happen to drift into northeast Australia and the coral sea just west of Cyclone Alfred.
By doing so, this influenced the steering winds around Alfred. In the days leading up to this,the steering winds around the cyclone had become very slack — a no-flow area — so it almost ground to a halt.
The upper trough to the west had enough pull that it started to shift Alfred west. There was a bit of back and forth over the days that followed but, eventually, a second upper trough from the southwest rolled into the west of the slow-moving cyclone and began to grab it properly to shift it west.
One of the biggest risks in tropical cyclones is torrential rain and flooding. The risks for this in Alfred will be extremely high and life threatening due to the slow progression to make landfall.
There are no strong steering winds to bring the storm onshore so the rain continues to fall over many days — increasing the flood risk.
That’s one of the factors that make this such an unusual storm, and such a threat to people in the affected areas.
Cyclone Alfred: Q&A on teh Rare Storm Threatening Eastern Australia
What is Cyclone Alfred and why is it considered a rare storm?
Cyclone alfred is a tropical cyclone threatening eastern Australia, specifically southeast Queensland and northern New South Wales. It is indeed considered rare due to a combination of factors, including its unusual westward trajectory after an initial right turn, and its slow progression. Typically, cyclones move southeast and dissipate over cooler waters. Alfred’s unusual path is attributed to erratic jet stream patterns, possibly influenced by planetary warming and residual upper energy.
Where is Cyclone Alfred expected to make landfall?
Cyclone Alfred is forecast to cross the Queensland coast between the Sunshine Coast region and the city of Brisbane. The exact location and timing are still critical concerns.
What are the primary dangers associated with Cyclone Alfred?
The primary dangers associated with Cyclone Alfred are:
Torrential Rain: Due to the cyclone’s slow movement, torrential rain is expected over several days.
Severe Flooding: Prolonged rainfall significantly increases the risk of life-threatening flooding.
Hazardous Winds: Early wind and rain have begun impacting eastern Australia
How are communities preparing for Cyclone Alfred?
Communities are preparing for Cyclone Alfred by:
Evacuating: Thousands of residents have been advised to evacuate.
Closing Schools and Suspending Public Transport: Schools are closed, and public transport is suspended.
Securing Property: Residents are preparing for the cyclone’s arrival, dealing with things such as sandbag shortages for flood protection.
What role is the jet stream playing in Cyclone Alfred’s unique path?
The jet stream, specifically the subtropical jet stream and upper-level troughs, is playing a meaningful role in Cyclone Alfred’s unusual westward drift. Normally, cyclones move southeast, but a bend in the upper jet stream winds initially steered the system north. Residual upper energy further influenced the steering winds, causing the cyclone to slow and eventually shift west due to the pull of upper troughs.
How does climate change relate to Cyclone Alfred?
While not the sole cause, climate change is suggested to be a contributing factor to Cyclone Alfred’s unusual behavior. Planetary warming has caused the jet stream to become more erratic and wobbly in recent years,influencing the cyclone’s path.
