1995–96 South Pacific cyclone season
Encyclopedia
The 1995–96 South Pacific cyclone season was one of the least active tropical cyclone seasons on record, with only four tropical cyclones occurring within the South Pacific Ocean to the east of 160°E

. The season officially ran from November 1, 1995 until April 30, 1996. The first storm developed on January 12, while the last one dissipated on April 2. During the season the most intense tropical cyclone was Severe Tropical Cyclone Beti, which reached a minimum pressure of 935 hPa (27.61 inHg) as it affected New Caledonia. After the season ended Beti's name was the only name to be retired from the tropical cyclone naming lists and was replaced with Bune, after it inflicted over 4.3 million (USD) worth of damage to Australia, Vanuatu, New Caledonia and New Zealand.

During the season, tropical cyclones were officially monitored by the Regional Specialized Meteorological Center

 (JTWC) and Naval Pacific Meteorology and Oceanography Center (NPMOC). Tropical cyclones that were located between 160°E and 120°W as well as the Equator and 25°S were monitored by RSMC Nadi while any that were located to the south of 25°S between 160°E and 120°W were monitored by TCWC Wellington. During the season the JTWC issued warnings on any tropical cyclone that was located between 160°E and 180° while the NPMOC issued warnings for tropical cyclones forming between the 180° and the American coast. RSMC Nadi and TCWC Wellington both used the Australian Tropical Cyclone Intensity Scale, and measured windspeeds over a 10-minute period during the season, while the JTWC and the NPMOC measured sustained windspeeds over a 1-minute period.

 event, most tropical cyclones that developed within the season occurred within the Coral Sea. The weak La Nina also affected the amount of tropical cyclones that occurred during the year with only 4 tropical cyclones occurring the season as a whole became one of the most inactive tropical cyclone seasons since 1969-70. The first tropical cyclone of the season, Yasi, developed on January 12 as a tropical depression before it was named on January 16. As a tropical cyclone, Yasi brought significant rain to both Fiji and Tonga before it dissipated on January 19 to the south of Papette in French Polynesia. After Yasi dissipated, no tropical cyclones were recorded in the basin until March 9; however on February 12, a tropical low developed to the west of New Caledonia. Over the next 24 hours the low deepened to about 1002 hPa before it crossed 160°E and moved into the Australian region where it became known as the Queen Elizabeth II storm. On February 22 and 23, a shallow tropical depression moved around the Fijian archipelago and caused some flooding of low lying areas in Vanua Levu. On March 9 and 10, Tropical Cyclones Zaka and Atu both developed near New Caledonia, about 1000 km (621.4 mi) apart and took similar tracks towards the southeast before becoming extratropical. On March 21, the final tropical cyclone of the season developed to the northeast of Vanuatu. Over the next couple of days the depression gradually developed further and was named as Beti, before it passed over Vanuatu and New Caledonia. On March 29, after it had passed over New Caledonia, Beti degenerated into an extratropical cyclone, before dissipating on April 2. After the season ended the name Beti was retired from the tropical cyclone naming lists and was replaced with the name Bune.

Tropical Cyclone Yasi

On January 12, RSMC Nadi reported that a tropical depression had developed over the Fijian island of Vanua Levu

, before the NPMOC initiated warnings on the system and designated it as 08P. At 0000 UTC on January 17, the NPMOC reported that the depression had reached its peak 1-minute sustained windspeeds of 85 km/h (50 mph) while RSMC Nadi reported that the depression had intensified into a tropical cyclone while it was located about 510 km (320 mi) to the southeast of Nukualofa, Tonga. However RSMC Nadi did not name it Yasi for another 12 hours, while the system reached its peak 10-minute sustained windspeeds of 85 km/h (50 mph). After it was named on January 17, Yasi accelerated towards the southeast, before it moved out of RSMC Nadi's area of responsibility. During January 18, the NPMOC issued their final warning because Yasi had degenerated into an extratropical cyclone. TCWC Wellington monitored Yasi's remnants for another day, before they dissipated about 1520 km (940 mi) to the south of Papette

. As the system stayed over water for most of its life there was no major impact reported on any islands, however Yasi did cause some minor damage after it brought some rain to Tonga.

Tropical Cyclone Zaka

On March 9, RSMC Nadi reported that a tropical depression had developed within an active convergence zone

 over New Caledonia. As a result this made the depression hard to locate with satellite imagery. However later that day despite the system being poorly organized, RSMC Nadi reported that the depression had intensified into a tropical cyclone and named it Zaka. As they named it RSMC Nadi reported that the system had reached its peak 10-minute sustained windspeeds of 65 km/h (40 mph) with further development of the system restricted by strong vertical wind shear. Early on March 10, the JTWC designated Zaka as Tropical Cyclone 20P, while it had its peak 1-minute windspeeds of 75 km/h (45 mph). RSMC Nadi then issued their final advisory at 0600 UTC, as Zaka had weakened into a tropical depression and was moving into TCWC Wellingtons area of responsibility. TCWC Wellington and the JTWC continued to monitor Zaka for another day before issuing their final warnings on March 11 as it became extratropical. Zaka dumped 376 mm (14.8 in) of rain on Vanuatu in just 24 hours.

Tropical Cyclone Atu

On March 4, the JTWC started to monitor an area of disturbed weather that was located within the Australian region about 900 km (560 mi), to the southeast of Port Moresby

. Over the next few days, the system remained weak and gradually moved southeast before it crossed 160°E and moved into the basin on March 9. During the next day, both the JTWC and RSMC Nadi started to monitor the system as a tropical depression as it moved through the Loyalty Islands

. On March 11, the depression intensified into a tropical cyclone as it moved southeastward, prompting RSMC Nadi to name it Atu at 1800 UTC. Early on March 12, the JTWC reported that Atu had reached its peak 1-minute windspeeds of 100 km/h (65 mph). Later that morning RSMC Nadi reported that Atu had reached its peak 10-minute sustained windspeeds of 85 km/h (50 mph). After it had peaked in intensity, Atu weakened under the influence of strong vertical windshear before the JTWC and RSMC Nadi issued their final advisories during March 13 as Atu had become extratropical. Atu's remnants were then monitored by RSMC Nadi and TCWC Wellington until they dissipated on March 18.

Severe Tropical Cyclone Beti

On March 19, the JTWC started to monitor a tropical disturbance that was located about 1145 km (710 mi) to the northwest of Suva, Fiji. Over the next couple of days the system moved towards the south and gradually developed further in an area of low vertical windshear, before the system was designated as Tropical Depression 23P by the JTWC and RSMC Nadi on March 21. Over the next couple of days, 23P moved further towards the south, before the depression started to move towards the southwest as a ridge of high pressure strengthened on March 23. Later that day, RSMC Nadi reported that the depression had intensified into a category 1 tropical cyclone and named it as Beti. During that day, Beti continued to develop further before the system moved into the Coral Sea

 and Malekula. As Beti moved into the Coral Sea, the system quickly intensified further, with RSMC Nadi reporting on March 25 that Beti had intensified into a category 3 severe tropical cyclone. As Beti intensified into a severe tropical cyclone, the ridge of high pressure weakened as it interacted with an upper level trough of low pressure. As a result, the system started to move towards the south-southeast.

Over the next couple of days Beti continued to intensify as it moved towards New Caledonia, before the JTWC reported at 1800 UTC on March 26, that Beti had reached its peak 1-minute sustained windspeeds of 195 km/h (120 mph). Six hours later, RSMC Nadi reported that the system had peaked as a category 4 severe tropical cyclone with 10-minute sustained windspeeds of 165 km/h (105 mph). Later on March 27, Severe Tropical Cyclone Beti made landfall on the Grande Terre island

 of New Caledonia near its peak intensity and quickly weakened into a category 2 tropical cyclone. During the next day, Beti moved towards the southeast under the influence of the trough, reemerging into the Coral Sea as a weakening tropical cyclone that had started to transition into an extratropical cyclone. Later on March 28, RSMC Nadi passed the primary warning responsibility of the cyclone to TCWC Wellington, before the JTWC issued their final advisory on Beti as it had become extratropical. Over the next few days, TCWC Wellington continued to monitor the remnants of Beti, as it came under the influence of a high pressure area and moved around the East Coast of New Zealand. The extratropical remnants of Beti then dissipated on April 2 about 1400 km (870 mi) to the southeast of Wellington.

While it was active, Cyclone Beti was responsible for 2 deaths and caused some damage in Australia, New Caledonia, New Zealand, and Vanuatu. The most significant damage occurred in New Caledonia where wind and flooding destroyed crops, gardens and caused disruption to the electricity network, water supply, road and telephone communications. Many homes and roads were also badly damaged, with over 50% of lower standard housing on the outskirts of Noumea damaged after rivers and creeks burst their banks. Press reports indicated that Beti inflicted between FF 22-27 million (4.3 -5.3 million USD) in damage to New Caledonia and that only a few injuries had occurred. Within Vanuatu, Beti caused about VUV

, Beti generated a high surf and long period swells that hit both eastern Australia and New Zealand. Within Australia, the high surf left several competitors in the Australian life surfing championships injured, while another competitor was killed after his boat was swamped by large waves. Within New Zealand, Beti's remnants caused flooding and mud-slips, which led to several roads being closed. A helicopter and its pilot were lost at the height of the storm, while they were traveling from Napier
