For this season, elevated activity is expected for New Caledonia. The predicted SST and rainfall distribution suggest a more active SPCZ than normal is possible from near the Solomon Islands to Fiji. A tsunami can arrive within minutes of a tremor or earthquake. 2020/21 Southwest Pacific Tropical Cyclone Season Long-Range Tropical Cyclone Outlook for the Southwest Pacific (TCO-SP) ...

Despite the risk reduction in some places, cyclones are still expected for countries that typically experience one or more named cyclones per year. Advice. Model SST, rainfall, and air pressure guidance favour near average TC activity for the 2020/21 Southwest Pacific tropical cyclone season. The NIWA and MetService assessment of named tropical cyclone (TC) activity indicates 8 to 10 named TCs could occur in the Southwest Pacific basin between November 2020 and April 2021. The highest cyclone frequency is found in the months from January to March. Southwest Pacific Tropical Cyclone Outlook, Southwest Pacific Tropical Cyclone Outlook - October 2020, Southwest Pacific Tropical Cyclone Outlook - October 2019, Southwest Pacific Tropical Cyclone Outlook - October 2018, Southwest Pacific Tropical Cyclone Outlook - October 2017, Air quality monitoring with low-cost sensors, ICES Expert Working Group Meetings – April 2017, http://www.meteo.nc/espro/previcycl/cyclA.php, https://doi.org/10.1038/s41598-020-67646-7. Figure 2: Number of TCs occurring for the main development season (November – April) in the Southwest Pacific (135°E to 120°W): (top panel) average number during 1981 to 2010 (normal); (centre panel) average number over selected five analogue seasons (Table 3); (bottom panel) departure from normal for the analogue seasons (difference between count in centre and top panels). This is the first year the product is available and we have incorporated it into the ICU outlook because it provides a different view from analogue and dynamical approaches. The risk of an interaction for New Zealand (with at least one cyclone coming within 550 km of the country) for the 2020/21 season is elevated. Oceanic and atmospheric forecasts for ENSO indicate moderate-to-strong La Niña conditions for the TC season are very likely. Temperatures can rise to 30°C, but average 26°C in Noumea. Cyclone Disaster Dashboard. All analogue seasons had at least one cyclone of category 3 or greater strength, and a majority of the analogue seasons (4 out of 5) experienced a minimum of three severe cyclones (≥ category 3). These are called hurricanes in the North Atlantic Ocean and cyclones in the South Pacific. Elevated TC presence is expected in and around the Coral Sea and north Tasman Sea, especially during the late season between February and April. b Average TC counts calculated for November-April TC season. Figure 1. The spatial anomalies shown for this TC outlook strongly indicate reduced risk of cyclones for American Samoa, French Polynesia, and the Cook Islands. Expected TC numbers are based on the NIWA Analogue method (see Table 2) and supported by the TCO-SP deterministic method. Developed by a … The area most likely to experience a tropical cyclone in the South Pacific is that of Vanuatu, New Caledonia, Fiji, Tonga, Niue and the islands of Wallis and Futuna. The historic long-term seasonal average is just over 10 named cyclones for the SW Pacific basin. TCO-SP also provides a different view from analogue and dynamical approaches. The storm stalled west of Vanuatu over the weekend and weakened slightly. It's not yet clear whether any remnants of tropical cyclone Uesi will make it to New Zealand. The table is therefore only generally indicative of how many cyclones might be expected for any given island group for the coming season. New Zealand also faces a higher risk of being battered by ex-tropical cyclones. Near normal activity is expected for Tokelau, Fiji, Vanuatu, the Solomon Islands and Papua New Guinea. For the coming Southwest Pacific TC season, the deterministic TCO-SP outlook suggests 9 named TCs may form (probable range of 7-10), indicating normal to below normal activity for the basin when compared with the 1981-2010 average of 11.4 TCs (Table 1, Table 4 and Figure 9). Tasman Sea and east of the country). Table 2: The average number of TCs passing close to the main South Pacific Island groups between November and April based on analogue guidance, but contains subjective assessments in some cases to be consistent with the wishes of the national meteorological services involved in generating this regional outlook. The Southwest Pacific basin covers 135˚E to 120˚W, therefore the forecast generated by NIWA extends 25˚ westward than the ECMWF forecast domain. The effects of ex-tropical cyclones can be spread over a large area, particularly if the decaying ex-tropical cyclone interacts with mid-to-high latitude weather systems. NIWA, MetService, MeteoFrance, BoM, NOAA and Pacific Island National Meteorological Services will all continue to track the progression of ENSO and TC activity, with an update to this guidance in January 2021 if needed. Category:Tropical cyclones in New Caledonia. This month also marks the start of the cyclone season in the Pacific. Elevated activity is expected in the Coral Sea offshore of Queensland, between the Solomon Islands and New Caledonia, and in the north-central Tasman Sea (including Norfolk Island). Tag: New Caledonia cyclone Yasa . Cyclone Erica developed from a monsoonal trough on 4 March just off Queensland. As such, an additional element used to hone the historic analogues for the coming TC season included years when ENSO conditions during November-April were reminiscent of moderate to strong La Niña. A Southwest Pacific tropical cyclone climatology and linkages to the El Niño–Southern Oscillation. While that doesn’t bode well for residents of the tropical nation, isn’t a bad thing for surfers residing on Australia’s East Coast. The average temperate hovers around 20-27 degrees Celsius year-round and there’s an average of 345 sunshine days annually. Development of an enhanced tropical cyclone tracks database for the southwest Pacific from 1840-2011. International Journal of Climatology, 32: 2240–2250. TC intensity is partly related to how long developing cyclonic systems reside in the tropics and gain support for their growth from underlying warm waters. Wheeler, 2008. Uesi may impact eastern Austrialia with … The rounded average interaction for New Zealand with an ex-tropical cyclone is two named systems per season. Humidity can become uncomfortable, but trade winds which blow for 250-300 days a year help temper this. Significant rainfall, extreme winds, hazardous marine conditions and coastal damage are all possible leading up to and during these events. Four of the five historic analogue seasons indicate more than one cyclone of category 4 strength or higher could occur. The outlook for the region to the east of the International Date Line largely shows reduced risk overall, but small areas of increased TC track numbers clustered near the International Date Line close to Fiji. Cyclone Cook has formed over Vanuatu and is predicted to intensify to category three as it approaches New Caledonia on Monday. This seasonal outlook is for normal to below normal activity in terms of overall named cyclone systems in the region. The analogue guidance has one primary cluster of enhanced activity extending from the Coral Sea to the south of New Caledonia. Part of the 2016–17 South Pacific cyclone season Meteorological history. Table 3: Previous analogue seasons and intensity of TCs that occurred in the Southwest Pacific during the November-April TC season . Diamond, P.R. In addition, TC activity is expected to be elevated across the north-central Tasman Sea region, encompassing the maritime area near Norfolk Island and to the northwest of New Zealand. The interplay of hemispheric-scale atmospheric circulation with the timing of short-term Madden-Julian Oscillation (MJO) activity on a 30 to 50-day cycle has significant bearing on regional TC activity. More about tropical storms On average, around ten cyclones develop off the coast of Australia every year, and the 2020/21 cyclone season’s set to be significant, with new research predicting 11 cyclones will hit Australia in the six months to 30 April 2021. The South Pacific Ocean recently moved into tropical cyclone season. For the coming season, important differences are expected between the western and eastern halves of the Southwest Pacific basin and also for early and late season activity. The season lasts from November 1 to April 30, and comprises about 10 tropical cyclones in that period - only one of which will affect New Zealand on average, MetService says. Near or above normal MSLP is predicted to the east of Fiji, particularly near and east of Samoa and American Samoa (Figure 7 & 8). Track data are courtesy of International Best Tracks Archive for Climate Stewardship (IBTrACS). The long-term TC climatology and the analogues we have identified indicate that a category 5 cyclone may occur (see Table 3). An ex-tropical cyclone climatology for Auckland, New Zealand. New Zealand should also remain vigilant as the season unfolds. Nevertheless, the maritime region between New Caledonia and New Zealand appears to have elevated risk for TC activity this season, and extra caution for those navigating that area (especially during the late season) is warranted. All rights reservedPrivacy Policy, 2016, Free phone within New Zealand: 0800 RING NIWA (0800 746 464) Contact details, Principal Scientist - Forecasting and Media. Some people, mostly those with a vested interest in having vessels visit New Zealand, will try to tell you that it is “very difficult” to return to the SW pacific Islands (New Caledonia, Vanuatu & Fiji) from Australia and that you are better off heading to New Zealand for Cyclone Season of you wish to revisit the SW Pacific Islands. "NZ should remain vigilant as the cyclone season unfolds. On average, nearly half of the TCs that developed since the 1969/70 season have reached at least category 3 cyclones with mean wind speeds of at least 64 knots (118 km/h). The cyclone is expected to move south-southwest over the coming days, passing just west of New Caledonia. The new model could improve early warnings, support advanced disaster management preparedness and save lives during the Southwest Pacific tropical cyclone season.. Renwick, 2015. For most of austral winter (June-August) and early spring 2020 (September), the ENSO system was neutral, but was progressing steadily toward La Niña (which we are now presently in). Powerful Cyclone Yasa hits Vanuatu and Fiji and then it aims directly towards Northern Island, New Zealand! The Pacific Islands may be facing an increased threat of a Tropical Cyclone this coming cyclone season as NOAA’s Climate Prediction Center confirm that a La Niña climate pattern has developed in the Pacific and is likely to persist through the winter. On average, at least one ex-tropical cyclone passes within 550km of New Zealand each year. An analysis of past TC tracks in the SW Pacific indicate they are exceptionally unlikely in September, although one system recently formed during this time. Be aware that New Caledonia can be hit by active tropical cyclones or storms, but such severe weather events remain unpredictable and relatively rare, mostly occurring between February and April. December 14, 2020. by marekkucera. Map plotting the track and the intensity of the storm, according to ... Cook subsequently made landfall on the Grande Terre Island of New Caledonia, between Houaïlou and Kouaoua at around 04:00 UTC (15:00 NCT) on April 10 where it started weakening due to frictional forces. When dangerous weather is forecast, please heed the advice of your local meteorological service, civil defence, or disaster management offices. Lorrey, A.M., G. Griffiths, N. Fauchereau, H.J. To help identify past ENSO conditions for the selection of analogue seasons, we used an ENSO index that combines the Southern Oscillation Index (SOI) with the most widely-used oceanic index of sea surface temperature anomalies in the equatorial central-western Pacific (NINO3.4). Past seasons with conditions similar to present suggest several cyclones that develop could intensify to at least category 3 strength. doi: 10.1002/joc.3753. Cyclone Yasa aims to New Zealand, Zazu shifts from Fiji southeastward. However the south of the South Island is still assessing flood damage after widespread flooding caused by torrential rain last week. This seasonal outlook is for normal to below normal activity in terms of overall named cyclone systems in the region. There is relatively low disagreement between the analogues for the total number of cyclones for this season, with the one exception being the 2007/08 season. Even small tropical storms can develop into major cyclones causing extreme damage to infrastructure. The consensus forms the basis for the full season (November-April) outlook for Southwest Pacific TC activity (and risk) for the 2020/21 season. Cyclone level 2 alerts are in effect for the communes of Houaïlou, Kouaoua, Canala, Thio, Yaté, Ouvéa, Lifou, and Maré. The new model could improve The South Pacific’s third major tropical cyclone this season is already bringing strong to gale force winds and heavy rainfall to Vanuatu, with New Caledonia likely to receive a direct hit later in the week.
