Reasons for the low activity during the year included a positive Indian Ocean Dipole occurring and the 2014–16 El Niño event.

Stan subsequently made landfall on Western Australia and impacted various commodities including oil, natural gas and iron ore.

Over the next few days, the system remained over water and dissipated during 15 February after it had produced some powerful, long period swells along Queensland beaches.

It was also noted that Category 5 severe tropical cyclones, with 10-minute sustained windspeeds of 196 km/h (122 mph) were known to occur during El Niño events.

[2] It was forecast that the region would less active than during previous years, with a 91% chance of a below average amount of tropical cyclones, because of the strong El Niño episode that had developed over the Pacific Ocean.

[6][7] This low activity was partially attributed to the 2014–16 El Niño event, which caused systems to be displaced eastwards into the South Pacific tropical cyclone basin.

Stan subsequently made landfall on Western Australia and impacted various commodities including oil, natural gas, and iron ore.

Over the next few days, the system remained over water and dissipated during 15 February after it had produced some powerful, long period swells along Queensland beaches.

[9] On 20 December, TCWC Jakarta issued an advisory as the low was inside their area of responsibility, as it was located about 567 km (352 mi) south-southwest of Tanjung Karang.

[10] TCWC Perth forecast the low would intensify to a tropical cyclone and move into the Western Region by 24 hours on 21 December.

[14][15] Over the next couple of days, the system gradually deepened further as it moved west-northwest inland and passed near Daly Waters and Katherine.

[14] On 27 January, the BoM reported that Tropical Low 08U had developed about 750 km (465 mi) to the north of Port Hedland.

Stan reached category 2 tropical cyclone strength at 8:00 pm AWST time, when it was located 280 km north of Port Hedland.

Category 1 strength hurricane-force winds formed around 9:30 am AWST the same day, near Rowley Shoales where Stan was 100 km south of the island.

Stan crossed the east Pilbara coast between Port Hedland and Wallal as a strong category 2 tropical cyclone at 2:00 am AWST.

[20] The Bureau of Meteorology (BoM) issued a Yellow alert for coastal communities between Pardoo and Mardie Station, which included the cities of Port Hedland, South Hedland, and Karratha, while a blue alert was put in place for areas between Bidyadanga to Pardoo, and between Mardie Station to Pannawonica.

[citation needed] Tropical Low 10U developed during 9 February within the central Coral Sea, about 900 km (560 mi) to the southwest of Honiara in the Solomon Islands.

[31] By this time Tatiana had started to move towards the east-southeast under the combined influence of the monsoon flow and a trough of low pressure.

The system subsequently peaked as a Category 2 tropical cyclone with 10-minute sustained winds of 95 km/h (60 mph) during 12 February, before it moved just out of the Australian region and into the South Pacific basin.

[28] After the system had degenerated into a subtropical low, it produced some powerful, long period swells along southeast Queensland beaches.

[citation needed] Tropical Low 14U developed within a monsoon trough near Vanderlin Island, in the southern Gulf of Carpentaria, on 14 March.

[48][49][50][51] During the season a total of 3 tropical cyclones received a name from BoM, either by TCWC Perth, Darwin, or Brisbane, when the system was judged to have 10-minute sustained windspeeds of 65 km/h (40 mph).
