Cyclone Kirrily: Landfall near Townsville, wind strength and flooding timeline

Cyclone Kirrily formed in the Coral Sea on 17 January 2024 and became one of Queensland’s major summer weather events. It reached Category 3 strength over water before crossing the coast near Townsville as a Category 2 system on 25 January, then weakened inland and helped drive heavy rain, flooding and travel disruption across western Queensland.

Key takeaways

• Tropical Cyclone Kirrily formed on 17 January 2024 and moved west towards the Queensland coast.
• The system reached Category 3 strength over the Coral Sea before weakening near landfall.
• BoM recorded a minimum central pressure of 978 hPa just before landfall.
• It crossed near Townsville as a Category 2 cyclone on 25 January 2024.
• After landfall, the remnant low brought heavy rain and flooding across Western Queensland.
• BoM, QFES and local authorities used warnings, maps and evacuation advice to reduce risk in storm surge zones.

Cyclone Kirrily track and timeline

The system began as a tropical low, 05U, over the Coral Sea and was later named Tropical Cyclone Kirrily by the Bureau of Meteorology. The Joint Typhoon Warning Center also tracked its movement while it was still offshore. BoM advice showed a westward track towards North Queensland, with early uncertainty about whether the centre would pass close to Cairns or further south near Townsville.

The BoM cyclone forecast map was a key source for residents watching the system’s expected path and possible landfall timing. Forecast updates changed as the track firmed, with the cyclone ending up on a more southern route than some early outlooks suggested. The tropical cyclone formation in the Coral Sea process for this system was monitored for several days before its intensification.

When did Cyclone Kirrily form?

BoM records show that Tropical Cyclone Kirrily formed on 17 January 2024 in the Coral Sea. It strengthened over warm water in the Australian region, then approached the coast late in the following week.

When did Cyclone Kirrily make landfall?

Kirrily crossed the Queensland coast near Townsville on 25 January 2024. BoM says Cyclone Kirrily peaked as a Category 3 severe tropical cyclone over the Coral Sea before weakening and crossing the coast near Townsville as a Category 2 tropical cyclone.

How strong was Cyclone Kirrily before landfall?

Just before landfall, BoM reported a minimum central pressure near 978 hPa at the coast. Over the Coral Sea the system had been stronger, with a lower central pressure (around 955 hPa) at its Category 3 peak. That pressure profile, along with the cyclone’s wind structure, supported strong gusts and damaging weather along parts of the coast.

What the Australian tropical cyclone intensity scale means

The Australian tropical cyclone intensity scale measures cyclones by their maximum sustained wind speed and the damage those winds can cause. On this scale, a Category 1 cyclone can still bring damaging winds, especially near the coast. Category 2 and Category 3 systems are stronger, with a greater risk of roof damage, broken trees and dangerous debris.

In Kirrily’s case, the key point is that its strongest phase occurred over water. By the time it crossed the coast near Townsville, it had weakened to Category 2. That does not mean it was harmless. Coastal winds, heavy rain and storm surge still created a serious risk, often requiring significant cyclone preparedness from local councils.

What category was Cyclone Kirrily at its peak?

BoM classed Kirrily as a Category 3 severe tropical cyclone at its peak over the Coral Sea. That peak strength occurred before the system weakened as it approached the coast.

What category was Cyclone Kirrily at landfall?

BoM says Kirrily crossed the Queensland coast near Townsville as a Category 2 cyclone on 25 January 2024.

Townsville, severe warnings and storm surge zones

Townsville was among the main population centres watching the system closely. BoM issued severe weather warning Queensland updates, and Queensland Fire and Emergency Services (QFES) repeated public safety advice as the coast prepared for damaging winds and coastal inundation. Information for families included child care subsidy emergency declarations for parts of North Queensland.

The Standard Emergency Warning Signal (SEWS) was used in emergency broadcasts to make the warnings stand out. For people in low-lying areas, storm surge zones were a major concern, especially where strong onshore winds could push seawater above the normal high tide line. Residents in those areas were urged to act early rather than wait for conditions to worsen. Local emergency management teams reviewed the severe weather season impacts to refine response plans.

What role did QFES play?

QFES supported local warnings, public safety messaging and response efforts as the cyclone approached and then moved inland. Its advice focused on securing property, listening to BoM updates and following evacuation directions where they were issued.

What did the warning messages focus on?

The main risks were gale force winds, heavy rainfall and storm surge. These hazards affected coastal communities first, then moved inland as the weather system weakened into a tropical low.

BoM cyclone forecast and the warning process

The BoM cyclone forecast for Kirrily changed as new observations came in. Forecasts are based on the available data at the time, so the path and strength can shift as the system evolves. For Kirrily, that meant regular updates to the forecast track, wind field and rainfall outlook.

BoM’s live tracking map was central to the response. It helped show likely landfall timing, which communities were most exposed, and how the rainfall risk would shift once the cyclone moved inland.

What did the Bureau of Meteorology tracking map show?

The Bureau of Meteorology tracking map showed the storm’s expected movement from the Coral Sea towards North Queensland, then inland across the state. That helped households, councils and emergency services plan for the next change in conditions. Users can view current active cyclones to see if any systems are mimicking this path.

Why did the forecast matter?

Forecasts matter because the timing of landfall, wind changes and heavy rain affects when warnings are issued, when roads close and when people in storm surge zones need to move to safer ground. Understanding how forecasts work helps the public interpret the uncertainty in these tracks.

How Kirrily compared with other Queensland cyclones

Every cyclone behaves differently, but Kirrily fits a familiar Queensland pattern: a coastal crossing followed by inland rain impacts. Unlike some cyclones that cause their worst damage at landfall, Kirrily’s rainfall impacts remained important after the wind field weakened.

The event also showed why a cyclone’s category alone does not tell the full story. A lower category at landfall can still lead to serious impacts if the system carries moisture inland and overlaps with already wet catchments. For more context, you can review historical cyclones that have traversed similar regions.

For readers comparing warning systems, Kirrily also highlights how local response settings have improved. The combination of BoM guidance, QFES messaging and SEWS alerts gave residents clearer information during the lead-up to landfall and the inland flood phase. Similar lessons were learned from Cyclone Althea, which previously impacted the Townsville region.

Forecast research from BoM

BoM later used Kirrily as a case study in tropical cyclone forecast improvement research. The paper linked with the event found that the new CoMorph-A convection scheme helped represent the cyclone’s evolution better than older configurations in some areas, especially the shift between convective rain and broader rainfall patterns.

That research matters because Kirrily exposed common forecast challenges: how quickly a cyclone will weaken near the coast, where the centre will cross, and how much rain will fall after landfall. Those questions matter for warnings, road closures and flood response across Queensland.
