1996–97 Australian region cyclone season
The 1996–97 Australian region cyclone season was an above average tropical cyclone season. It ran from 1 November 1996 to 30 April 1997. The regional tropical cyclone operational plan also defines a tropical cyclone year separately from a tropical cyclone season, and the "tropical cyclone year" ran from 1 July 1996 to 30 June 1997.
Tropical cyclones in this area were monitored by four Tropical Cyclone Warning Centres (TCWCs): the Australian Bureau of Meteorology in Perth, Darwin, and Brisbane; and TCWC Port Moresby in Papua New Guinea.
On 9 July, TCWC Perth reported that a tropical low had developed within the near-equatorial trough of low pressure, located about 500 km (310 mi) to the northeast of the Cocos Islands. During that day the system moved to the southwest around a weak mid-upper level anticyclone, before it came under the starting to move southwards during 10 July. At 1000 UTC that day, TCWC Perth reported that the low had developed into a category one tropical cyclone, and named it Lindsay as the system reached its peak 10-minute sustained windspeeds of 75 km/h (45 mph). At 1500 UTC, the JTWC reported that Lindsay was becoming better organized and issued a Tropical Cyclone Formation Alert on the system. Six hours later while Lindsay was at its 1-minute peak intensity of 65 km/h (40 mph), the JTWC designated the system Tropical Cyclone 01S and started to issue warnings on it. After the JTWC had initiated warnings on the system, it began to rapidly weaken as it came under the influence of strong upper level north-westerlies. During the next day, both the JTWC and TCWC Perth issued their final advisories on Lindsay as it weakened below cyclone intensity and became extratropical. Lindsay's remnants were tracked as they moved towards the southeast until they were absorbed into a broad trough of low pressure on 13 July.
Melanie formed from a low near Cocos Island on 30 October 1996. It deepened to a category 2 storm overnight on 1 November and it moved westwards, with a subsequent name change to Bellamine. It dissipated on 11 November.
A tropical depression formed on 12 December 1996 near Timor. The depression moved south before being classified as a cyclone on 14 December and was named Nicholas. The storm made landfall west of Derby, Australia as a tropical storm on the 15th and dissipated the next day.
Ophelia formed between two tropical cyclones, Nicholas (near the north Kimberley coast) and Elvina near 80°E, to the east of Christmas Island on 13 December 1996. Its track was somewhat unusual in that it moved towards the southeast for most of its lifetime. The weak cyclone had no impact on Christmas Island or northwest Australia and dissipated on 19 December.
Fergus was a Category 2 storm that formed in the Pacific Ocean, lasting from 29 December to 31 December 1996 until becoming extratropical near New Zealand. The storm dropped heavy rainfall across an already saturated area, with totals of over 16.5 inches (420 mm) near Thames. The rainfall led to widespread flooding and forced many to evacuate. Severe road damage occurred, with some roads remaining closed for over a week. Gusty winds from Fergus downed trees and power lines, and caused property damage.
A weak cyclone, Phil crossed the northern part of Australia between 26 December and 27 December 1996. The storm then moved westward where it encountered vertical wind shear and dissipated on 31 December. It reformed in the South-West Indian Ocean basin on 8 January 1997 and remained as a tropical disturbance until it finally dissipated on 16 January.
