Cyclone Narelle to reach category 5 before Queensland landfall
Tropical Cyclone Narelle is forecast to become a powerful category 5 system – the highest tier on the Australian cyclone scale – before making landfall over northern Queensland later this week. Narelle strengthening over Coral Sea Tropical Cyclone Narelle first became a tropical cyclone on Tuesday and had quickly strengthened to a category 2 system by Tuesday night. At 10 am AEST on Wednesday, Narelle was still a category 2 tropical cyclone, located about 970 km east northeast of Cooktown. Narelle is forecast to track towards the west over the next few days, allowing it to move through a region that will support steady-to-rapid intensification as it approaches the east coast of the Cape York Peninsula. The Bureau of Meteorology’s latest forecast track map, issued at 10:42 am AEST on Wednesday, predicts that Narelle will become a category 3 severe tropical cyclone by Wednesday night. Further strengthening is forecast from Thursday, with the system expected to reach category 4 intensity by Thursday morning and possibly hitting category 5 by Friday morning. At this stage, Tropical Cyclone Narelle could approach the coast as a category 5 system but will most likely make landfall as a category 4 system on Friday. The Bureau notes that “A category 5 peak intensity is forecast. This is expected to occur shortly before interactions with the Queensland east coast increase, and consequently some weakening before the centre of Narelle is anticipated. If Narelle tracks a little further north it may maintain category 5 intensity until landfall.” It’s important to point out that there is currently some uncertainty regarding how quickly Narelle will approach the Qld coast. It could move faster than expected and arrive on Thursday, which would limit how much it can intensify before landfall. Conversely, it could also track towards the west slower than is currently being forecast, which would give the system more time to gain strength before crossing the coast.

What impacts to expect from Narelle The impacts from Narelle will depend on its strength at landfall. At this stage, Narelle will most like be a category 4 severe tropical cyclone when it reaches the east coast of the Cape York Peninsula. This strength would allow Narelle to produce average wind speeds in excess of 160 km/h and gusts above 225 km/h. Should Narelle manage to cross the coast as a category 5 tropical cyclone, average wind speeds would likely be above 200 km/h and gusts of 280 km/h or higher. Heavy rain, flash flooding, large waves, storm surge and coastal inundation are all likely to occur as Narelle makes landfall, regardless of whether Narelle is category 4 or 5 as it crosses the coast. At this stage, landfall will most likely occur somewhere between Port Douglas and Lockhart River. This is a region that already holds a world record for the largest storm surge from a tropical cyclone, when Tropical Cyclone Mahina caused a 13 metre storm surge near Bathurst Bay in March 1899.

Tropical cyclones typically weaken after making landfall. While this post-landfall weakening is likely to occur after Narelle crosses the Qld coast, the system should pass over the Cape York Peninsula within about 12 hours. Narelle could still be a category 1 tropical cyclone when it emerges off the west coast of the Cape York Peninsula. Forecast models suggest the cyclone will then reintensify as it tracks over warm water in the Gulf of Carpentaria this weekend. Based on current model guidance, Narelle could make a second landfall over the Northern Territory’s Eastern Top End on the weekend, possibly as a severe tropical cyclone (category 3 or higher). What Narelle does beyond this weekend is currently difficult to predict. Some computer models suggest that it will continue moving towards the west, carrying heavy rain over the NT and Kimberley on the weekend and early next week. The system could emerge off the north coast of Western Australia next week and possibly intensify once again. While forecast confidence is low for next week, there is a chance Narelle will impact the Pilbara coast at some point next week. It is incredibly rare to see a single tropical cyclone impacting three Australian states. The last time this happened was in 2005 when Severe Tropical Cyclone Ingrid followed a similar path, forming over the Coral Sea before making landfall in Qld, the NT and then WA. How to prepare for Narelle Anyone in northern Australia should get prepared and stay informed during this tropical cyclone. The Bureau recommends the following actions for residents in Qld: Stay informed by checking your local government’s Disaster Dashboards for the latest updates. For cyclone preparedness and safety advice, visit the Get Ready Queensland website www.getready.qld.gov.au For non-life threatening emergency assistance contact State Emergency Services (SES) online via the SES Assistance QLD App, Apple , Android, online www.132500.qld.gov.au, or call 132 500 from anywhere in Queensland. The NT Police, Fire and Emergency Services and WA’s Department of Fire and Emergency Services also have useful information on their websites to help plan and prepare for tropical cyclones.

Sydney storms cause flash flooding, more rain to come
Severe thunderstorms caused intense rain and flash flooding in parts of Sydney on Wednesday morning, with more rain and storms on the way in the coming days. A relatively weak southerly change moving along the central NSW coastline on Tuesday night into Wednesday morning, combined with a mid-level trough, caused heavy showers and thunderstorms to spread through parts of Sydney, the Illawarra and the Central Coast. The heaviest rain fell over Sydney’s Lower North Shore and Eastern Suburbs and on the Central Coast. Mosman received 95 mm in one hour early on Wednesday morning, and 130 mm between midnight and 9 am on Wednesday. Other notable rainfall rates on Wednesday morning included: 64 mm in 60 minutes at Pearl Beach 41 mm in 30 minutes at Rose Bay and Allambie 44 mm in 30 minutes at Cora Creek, Norah Head and Little Bay Rain rates above 10 mm in 10 minutes are typically enough to cause flash flooding in Sydney. Unsurprisingly, there were reports of flash flooding around Bondi and Rose Bay in response to Wednesday’s early morning downpours.

More rain to come Onshore winds combining with low pressure troughs will continue to cause showers and thunderstorms over NSW each day during the remainder of this week. This wet and stormy weather is likely to affect Sydney and surrounding areas, with potential for further severe thunderstorm activity. Severe storms are also likely to affect other areas of NSW this week as a broad inland trough interacts with the moisture-laden air feeding in from the Tasman Sea. The map below shows how much rain is predicted to fall between Wednesday and Friday. Image: Forecast accumulated rain during the 72 hours ending at 11pm AEST on Friday, March 20, 2026. Source: Weatherzone. As of 10am AEST on Wednesday, a severe weather warning was in place for heavy rain parts of the Upper Western district in northwest NSW, due to the inland trough. Further severe weather and thunderstorm warnings may be issued in the coming days, so be sure to check the latest warnings in your area.

Queensland bracing for severe tropical cyclone
A tropical cyclone is likely to hit northern Queensland later this week, with the Bureau of Meteorology predicting a category three severe tropical cyclone to make landfall in the state’s north. Tropical low gaining strength A tropical low is currently gaining strength over the northern Coral Sea. At 10am AEST, this low was located about 890 km to the east northeast of Willis Island, approximately 1,300 km off the Qld coast.

The low pressure system is expected to move towards the west over the next few days, likely gaining strength as it traverses the warm northern Coral Sea and heads towards Qld. Landfall in Qld possible later this week The Bureau of Meteorology expects the system to become a tropical cyclone by Wednesday and reach category three strength on Thursday or Friday. Based on the Bureau’s current forecast track, this system could approach the eastern side of the Cape York Peninsula as a category three severe tropical cyclone on Thursday or Friday. Some forecast guidance even suggests this system could make landfall as a category four tropical cyclone. If this system does make landfall as a severe tropical cyclone, it would be capable of causing: Destructive winds with sustained wind speeds possibly reaching 140 to 160 km/h Heavy rainfall causing flash flooding Large waves and abnormally high tides that could cause flooding in low-lying coastal areas Northern Territory next in line After crossing the Cape York Peninsula and briefly weakening later this week, computer models suggest the system could reintensify over the warm Gulf of Carpentaria and make a second landfall over the eastern Top End in the Northern Territory over the weekend. It’s too early to know with much confidence where the system will move beyond the weekend. However, some models predict that it will weaken while tracking over the Top End and Kimberley early next week before passing to the north of Western Australia and regaining strength in the middle of next week. If this happens, it may also cause tropical cyclone impacts in parts of northern WA next week. This system has the potential to cause severe weather in three states this week and next week, so anyone in northern Australia should pay close attention to the latest tropical cyclone advisories and track maps to stay up to date with the most accurate information. If this system does become a tropical cyclone, it will be named Narelle.
