“Severe Tropical Cyclone Narelle began life near the Solomon Islands on March 16.”

“Narelle crossed the Cape York Peninsula last Friday as an intense but compact category 4 system.”

“Narelle has travelled more than 5,700 kilometres since it formed as a system near the Solomons, according to the Bureau of Meteorology.”

“It is relatively rare for an individual tropical cyclone to affect Queensland, the NT and WA.”

“The last time a cyclone affected Queensland, the NT and WA was Severe Cyclone Ingrid in 2005 and Cyclone Steve in 2000.”

“The final path of Narelle is likely to be very similar to Steve, with its final dissipation in the Great Australian Bight.”

“Narelle is now twice the size it was when it reached far north Queensland a week ago — as measured by the area of strong gales around its eye.”

“Damaging winds now extend 200–260km from the centre, while destructive storm-force winds extend 110–210km, and the very destructive core of hurricane-force around the eye is 90–130km wide.”

“Dangerous storm surge and ocean inundation is also a high risk for exposed coastal locations along its path.”

“Wind and storm surge damage from the cyclone has been minimal, as it has tracked over more sparsely populated areas.”

“Its worst impacts have been heavy rain and flooding across NT catchments, which were already saturated from weeks of monsoonal rain.”

“Narelle’s track, forward speed and intensity have been remarkably predictable compared with many cyclones in the Australian region.”

“Prevailing easterly winds under the cyclone, associated with a subtropical high pressure ridge over southern Australia, have propelled it along at 15–25km per hour over the past week.”

“Narelle is now being steered around the northwestern periphery of the same high-pressure system, and this is why its track is now more to the south southwest.”

“It is expected to intensify over warm ocean waters. It will continue to move in a more southerly direction and maintain intensity as a dangerous category 4 cyclone until later today, before weakening to a still severe category 3 system near Shark Bay.”

“The towns of Onslow and Exmouth are expecting severe impacts as the core winds pass over them, with wind gusts of up to 250km per hour.”

“Further south, Carnarvon is expecting winds up to 200km per hour this afternoon.”

“Coral loss percentage (60-80%) is specific.”

“The weakening over land south of Denham and interaction with an upper trough leading to category 2 is another.”

“Kalbarri and Northampton recalling damage from Seroja in 2021 is a historical claim.”

“Perth avoiding the core during extra-tropical transition is a claim.”

“The rain forecast for the Wheatbelt is a factual statement.”

“Tropical cyclones becoming more intense, studies confirming this, and the decline in frequency but increased intensity in the Australian region are claims based on studies.”

“The mention of needing attribution studies for linking Narelle to global heating is a claim about current research.”
