REMARKS:
Tropical cyclone Narelle has weakened to category 2 strength as it moves west
over land towards the Gulf of Carpentaria.
The centre remains trackable on Weipa radar with reasonable confidence.
Satellite imagery shows a centre displaced to the west, suggesting the system
is becoming somewhat tilted under moderate to strong easterly deep layer shear.
Subjective Dvorak is no longer applicable with the centre over land, with most
objective aids similar. Peripheral gales are occurring intermittently at Weipa,
some 80 km to the NNW of the estimated centre. There have been no other recent
proximate observations. Intensity estimated at 55 kn based on a standard decay
rate over land, with low confidence.
CIMMS wind shear analysis at 0300 UTC shows upper easterlies over the system
contributing to an analysed deep layer wind shear of around 25 to 30 knots. The
system is forecast to maintain low end category 2 strength as it moves into the
Gulf of Carpentaria over water again tonight. Environmental conditions are
forecast to remain similar with the system lying near the northern periphery of
the upper ridge and potentially continuing to experience moderate to strong
easterly shear, offset by a very moist environment with warm SSTs (>29C) along
the forecast track. Most NWP guidance suggests reintensification and category 3
strength is forecast prior to landfall on the eastern Northern Territory coast
on Saturday night, which is consistent with a standard rate of development.
A strong mid-level ridge extending across Australia into the Coral Sea will
remain the dominant steering mechanism for Narelle well into next week. There
is high confidence in a westward forecast track across northern Australia.
Following landfall over the Northern Territory overnight on Saturday, Narelle
will then move across the Top End and off the Kimberley coast next week, where
redevelopment into a tropical cyclone is again likely.

Tropical Cyclone Warning Centre
Media: Transmitters serving the area between Lockhart River and Cape Melville and inland to Weipa and Pormpuraaw are requested to USE the Standard Emergency Warning Signal before broadcasting the following warning.
TOP PRIORITY FOR IMMEDIATE BROADCAST
TROPICAL CYCLONE ADVICE NUMBER 22
Issued at 4:43 pm EST on Friday 20 March 2026
Headline:
Tropical Cyclone Narelle at category 2 strength moving west and impacting Aurukun.
Areas Affected:
Warning Zone
Queensland: Western Cape York Peninsula between Mapoon and Pormpuraaw, including Weipa, Aurukun, and adjacent inland areas.
Northern Territory: Nhulunbuy to Port McArthur, including Borroloola, Numbulwar, Alyangula, and Gapuwiyak.
Watch Zone
Northern Territory: Extending west to include Ramingining, Bulman, and Ngukurr.
Cancelled Zone
Eastern Cape York Peninsula including Lockhart River and Coen.
Details of Tropical Cyclone Narelle 34U at 4:00 pm AEST:
Intensity: Category 2, sustained winds near the centre of 100 kilometres per hour with wind gusts to 140 kilometres per hour.
Location: within 30 kilometres of 13.3 degrees South 142.2 degrees East, estimated to be 55 kilometres east of Aurukun and 630 kilometres east of Alyangula.
Movement: west at 18 kilometres per hour.
Tropical Cyclone Narelle is moving westwards across western Cape York Peninsula towards Aurukun, where impacts are expected over the next few hours. Narelle has continued to weaken, though currently remains a category 2 system.
Narelle will continue to move west into the Gulf of Carpentaria tonight, where it is expected to strengthen again to a severe tropical cyclone before impacting the eastern Northern Territory from late Saturday.
Hazards:
Queensland:
DESTRUCTIVE WIND GUSTS to 150 km/h are likely near the centre of Narelle, including the Aurukun area, as it moves west into the Gulf of Carpentaria over the next few hours.
Gales with DAMAGING WIND GUSTS to 120 km/h are likely between Weipa and Cape Keerweer as Narelle moves into the Gulf of Carpentaria this afternoon and evening. These DAMAGING WIND GUSTS may extend to coastal areas between Mapoon and Pormpuraaw later tonight depending on the movement and development of Narelle in the Gulf.
HEAVY RAINFALL which may lead to FLASH FLOODING with LOCALLY INTENSE RAINFALL is likely in the western half of Cape York Peninsula Pormpuraaw and Mapoon today.
Once Narelle moves into the Gulf of Carpentaria, tides on the western Peninsula between Weipa and Kowanyama may be higher than normal. LARGE WAVES may produce MINOR FLOODING of low-lying coastal areas.
Northern Territory:
VERY DESTRUCTIVE WINDS with gusts to 195 km/h are forecast to develop in coastal areas between about Birany Birany and Numbulwar, including Groote Eylandt, late on Saturday afternoon and overnight into Sunday as Narelle approaches from the east.
DESTRUCTIVE WIND GUSTS to 160 km/h are possible from south of Nhulunby to Nathan River on Saturday night or Sunday morning depending on the movement of Narelle.
GALES with DAMAGING WIND GUSTS to 120 km/h are forecast to develop in coastal and adjacent inland areas between Gapuwijak and Port McArthur, including Nhulunbuy and Borroloola, from Saturday afternoon and overnight into Sunday. These GALES may extend west to Ramingining, Bulman, and Ngukurr on Sunday.
HEAVY RAINFALL which may lead to FLASH FLOODING is likely to develop for coastal and adjacent inland areas over the eastern Top End between Port McArthur and south of Nhulunbuy from Saturday afternoon and evening. LOCALLY INTENSE RAINFALL leading to DANGEROUS AND LIFE-THREATENING FLASH FLOODING is likely over the eastern Top End between Numbulwar and Birany Birany, including Groote Eylandt, from Saturday afternoon and evening.
Tides will be higher than normal between Nhulunbuy and Port McArthur later Saturday and Sunday. LARGE WAVES may produce MINOR FLOODING of low-lying coastal areas. A potentially DANGEROUS STORM TIDE between Alyangula and Port Roper is possible as the cyclone centre crosses the coast with DAMAGING WAVES and DANGEROUS FLOODING.
Recommended Action:
Queensland:
- People in the path of the cyclone should stay calm and remain in a secure shelter - above the expected water level - while the destructive winds continue.
- Do not venture outside if you find yourself in the eye of the cyclone - destructive winds from a different direction could resume at any time.
- There may be powerlines down, broken glass and other hazards.
- Follow the instructions and advice of Police, Emergency Services personnel and local authorities.
- Stay informed by checking your local government s Disaster Dashboards for the latest updates.
IF YOUR LIFE IS IN DANGER PHONE TRIPLE ZERO (000) IMMEDIATELY.

- 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.
Northern Territory:
NTES advises:
People between Nhulunbuy and Port McArthur, including Borroloola, Numbulwar, Alyangula, and Gapuwiyak, should immediately commence or continue preparations, especially securing boats and property.
People further west incuding Ramingining, Bulman, and Ngukurr, should consider what action they will need to take if the cyclone threat increases.
- For cyclone preparedness and safety advice, visit the Secure NT website at http://www.securent.nt.gov.au
- For emergency assistance call the Northern Territory Emergency Service (NTES) on 132 500 (for assistance with storm damage, rising flood water, fallen trees on buildings or roof damage).
Next Advice:
The next advice will be issued by 8:00 pm AEST Friday 20 March.
This warning is also available through TV and Radio Broadcasts; the Bureau's website at www.bom.gov.au or call 1300 659 210. The Bureau and the State Emergency Service would appreciate this warning being broadcast regularly.
