Businesses across northern AUS on alert with high risk of two cyclones

Two tropical cyclones could form in the Australian region by the start of next week, one in the Coral Sea and the other off the north coast of WA. Our team of meteorologists have been helping our clients assess the potential risks to their businesses in the coming week.

It has been one week since Severe Tropical Cyclone Zelia made landfall to the east of Port Hedland in WA’s Pilbara region. That powerful cyclone dumped hundreds of millimetres of rain and caused widespread flooding after crossing the coast as a high-end category four system last Friday.

Now, two other areas of low pressure near northern Australia are being watched closely by meteorologists because they both have a high risk of becoming tropical cyclones in the coming days.

One of the tropical lows is located to the north of WA and has been showing clear signs of rotation over the past two days. This spin is a crucial part of tropical cyclone development and if it continues to get stronger in the coming days, we could be looking at another tropical cyclone off WA’s north coast.

Forecast models suggest that this low will move towards the west or southwest in the next few days, which will take it through a region where favourable environmental conditions should allow it to strengthen.

The Bureau of Meteorology gives this system a 60% chance of becoming a tropical cyclone on the weekend. The Bureau has also started issuing forecast track maps for the system, showing that it could become a category three severe tropical cyclone early next week. At this stage the soon-to-be tropical cyclone is expected to remain away from the Australian coast, although it’s forecast track may change in the coming days.

The other developing tropical low is located over the northern Coral Sea, to the east of northern Qld. This system is expected to move towards the south or southeast in the coming days, away from the Qld coast, while gradually gaining strength.

This system is expected to develop more slowly than the one near WA, however it could still become a tropical cyclone. The Bureau of Meteorology currently gives this low a 55% chance of becoming a tropical cyclone during the first half of next week.

The future movement of this Coral Sea tropical low/cyclone is highly uncertain. Some forecast models anticipate that the system will remain offshore, while others suggest that it could turn and approach the Qld coast next week. It’s too early to know where this system will move next week, so meteorologists will be closely watching new computer model runs in the next few days for more reliable information.

Why Queensland has been getting all the rain

Multiple flooding events have occurred in Queensland since the start of 2025, but why? Last month was Australia’s hottest and 4th-wettest March on record. Queensland was especially wet, registering its 3rd wettest March on record. This moisture combined with the very warm temperatures around the country to bring the warmest March minimum temperatures on record […]

Queensland’s lowest solar production week in over 6 months

Thick and extensive cloud over Queensland last week caused solar production to plummet to its lowest level since last winter. A monsoonal burst combined with an active phase of the Madden-Julian Oscillation (MJO) over northern Australia last week, leading to widespread flooding rainfall and extensive cloud cover across Queensland. The image below shows the cloud […]

‘Mini tornado’ to be officially recognised on Fujita scale

This article was written for April Fools Day. It is not factual. A new category will be added to the Fujita scale from 2026 to formally recognise the ‘mini tornado’. The Fujita scale, and the revised Enhanced Fujita scale, are widely accepted scales used for rating tornado intensity. They both use damage assessments from past […]

Powerful bombing Tasman Low brings large waves to NSW ports

A powerful Tasman Low spinning off Australia’s East Coast is whipping up large waves along coastal NSW. A low pressure trough that slowly made its way from outback Queensland and over NSW over the past week, delivering widespread flooding, moved off the NSW coast this weekend. Very warm sea surface temperatures, along with support from […]
