Reduced TC activity is expected east of the International Dateline. The dynamical guidance generally agrees with the analogue guidance for TC count and severity, but has two distinct clusters of above normal amounts of activity (Coral Sea and south of Vanuatu and Fiji). To find past analogues that describe the climate state leading into the upcoming TC season, the conditions for May 2020 through to the beginning of October 2020 were examined for the tropical Pacific. Summary of analogue, dynamical and deterministic guidance for the ICU TC outlook. In many cases they’ll spend the best part of their short-lived existence tucked away inside the swell … 2020/21 Southwest Pacific Tropical Cyclone Season Long-Range Tropical Cyclone Outlook for the Southwest Pacific (TCO-SP) ...

Some of the decaying ex-tropical cyclone systems were also associated with high rainfall, damaging winds and amplified coastal wave conditions. Even small tropical storms can develop into major cyclones causing extreme damage to infrastructure. December 14, 2020. by marekkucera. Development of an enhanced tropical cyclone tracks database for the southwest Pacific from 1840-2011. International Journal of Climatology, 32: 2240–2250. 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. See https://tcoutlook.com/swpacific/ for more details related to this part of the outlook. It was also too early to tell whether any possible remnants could impact New Zealand, but he said there was no threat to the country this week. For the coming season, at least 3 cyclones are anticipated to reach at least category 3 strength, with mean wind speeds of at least 118 km/h winds. In New Caledonia, the hot season is from December to March. Last Update - October 15, 2020. As such, the tropical cyclone guidance for November 2020 to April 2021 is built on the five remaining analogue seasons identified above. News Item Content. Table 1: Island Climate Update (ICU) consensus outlook for November 2020-April 2021 tropical cyclone activity based on combining NIWA analogue model, international dynamical climate model and TCO-SP deterministic statistical model outlook results. If an ex-tropical cyclone comes close to the country, there is a near-equal probability of it tracking to either the east or west of the North Island, and landfall of a degrading ex-tropical cyclone is possible. Activity in general is expected to increase during the late season, especially for islands west of the International Date Line around the Coral Sea. "Between New Caledonia and Australia - Queensland, in particular - usually we get pretty big seasons in La Nina years." New Zealand’s National Institute of Water & Atmospheric Research (NIWA) and Meteorological Service of New Zealand (MetService) formulated this seasonal tropical cyclone outlook, along with contributions from the University of Newcastle and meteorological forecasting organizations from the Southwest Pacific, the Australian Bureau of Meteorology, MeteoFrance and the Pacific Island National Meteorological Services. On average, New Zealand usually experiences at least one interaction per season with an ex-tropical cyclone. Four of the five historic analogue seasons indicate more than one cyclone of category 4 strength or higher could occur. For the coming TC season, the risk for New Zealand is elevated. Please be sure to comply with any instructions you may be given. 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). Much of New Zealand is in desperate need of rain, with widespread drought in the upper North Island.

For the coming 2020/21 season, the deterministic TCO-SP outlook for Southwest Pacific TC season suggests 9 named TCs will 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 4 and Figure 9). 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 cyclone is expected to move south-southwest over the coming days, passing just west of New Caledonia. It is normally issued during the TC season from 1 Nov to 30 Apr, but also outside this period if required for a potential or active cyclone. Learn more about New Caledonia’s weather and start planning your dream holiday. 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. Tasman Sea and east of the country). 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. When dangerous weather is forecast, please heed the advice of your local meteorological service, civil defence, or disaster management offices. The historic long-term seasonal average is just over 10 named cyclones for the SW Pacific basin. Temperatures can rise to 30°C, but average 26°C in Noumea. Category:Tropical cyclones in New Caledonia. Based on seasons with similar background climate conditions to the present, TC activity in the coming season is expected to be elevated around the Coral Sea between the Queensland coast and New Caledonia. Last Update - February 10, 2020. Mr Meke said Uesi was currently a category two cyclone with winds of up 95 km/hr. And in Dunedin, there would be fine weather until showers set in on Friday, with the temperature dropping down to a high of just 14C. Wheeler, 2008. 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). This owes to a moderate-to-strong La Niña signal, which the models are capturing, increasing forecast confidence. New Caledonia also experiences earthquakes, tsunamis and bushfires. Vanuatu and New Caledonia typically experience the greatest TC activity, with an average of about two or three named cyclones passing close to those islands each year. Figure 1. More about tropical storms Cyclone season in the region typically lasts from November to April but storms can occur outside this period. After that, there were earlier suggestions it could move into the Tasman Sea. Using the CEI, we selected analogue TC seasons for the 2020/21 outlook, highlighting seasons when the equatorial SSTs and the SOI were indicative of a transition from neutral ENSO conditions in winter-spring to La Niña conditions during summer-autumn. There is an equal probability of a decaying ex-tropical cyclone tracking to the east or west of the North Island based on historic track data (Figure 3). The Australia Bureau of Meteorology monitoring of the Niño3.4 region (central-western equatorial Pacific Ocean) shows sea surface temperature anomalies are below 0.8°C. Since it is farther south than most of the other islands in the South Pacific, New Caledonia generally has a very sunny, moderate climate. Normal or slightly reduced activity is expected for Tonga, Wallis & Futuna, and Samoa. evacuation orders). Cyclone season officially kicks off on November 1st, but it's usually not until the new year that this kind of action kicks into gear. Significant rainfall, extreme winds, hazardous marine conditions and coastal damage are all possible leading up to and during these events. Tropical cyclone season is upon us and a new storm is brewing in the South Pacific. Cyclone Uesi is Tracking just west of New Caladonia gusty and strong winds and large waves will better the island. By night, it can cool down to below 60°F. Scientific Reports, 10, 11286, https://doi.org/10.1038/s41598-020-67646-7. [1] The South Pacific convergence zone (SPCZ) is an extensive Southern Hemisphere atmospheric circulation feature that contains one of Earth’s most expansive and persistent convective cloud bands. We used a high-quality set of past TC tracks from the International Best Tracks Archive for Climate Stewardship (IBTrACS) which covers 135°E to 120°W longitude to draw on past TC track patterns for the seasonal outlook. In the Pacific Islands, please contact your local national meteorological service for information about how this guidance should be interpreted. Therefore, all communities should remain alert and well-prepared for severe TC events. Tropical cyclones are categorised in strength from 1 to 5, with 5 being the most intense. Near normal activity is forecast to extend from the Solomon Islands to Niue (including Fiji and Tonga) with pockets of below normal activity farther to the east (Samoa, American Samoa, Cook Islands). The year label notes the first month in the analogue year selection (i.e. Having no insurance for the boat meant that all our material possessions were at stake, not mentioning the risk of getting hurt, or even worst. This means that some tropical cyclone tracks for the coming season, if La Niña fully matures, may have straighter trajectories than normal. 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’s SW Pacific TC outlook spans four areas of responsibility overseen by international monitoring and forecast agencies (RMSC Nadi, the Australian TCWC, TCWC Port Moresby and TCWC Wellington). Get up to date information on storms, cyclones and other weather events in the New Caledonia region. This provides confidence in the statistical outlook for expected cyclone strengths, and support for a conservative range of 3-4 severe tropical cyclones for this outlook. It's expected to be a cloudy weekend, however a high of 28C is forecast on Sunday. Vanuatu and New Caledonia typically experience the greatest activity, with an average of 2 or 3 TCs passing close to land each year. Expected TC numbers are based on the NIWA Analogue method (see Table 2) and supported by the TCO-SP deterministic method. Above average SSTs are also forecast for the waters surrounding New Zealand (e.g. This month also marks the start of the cyclone season in the Pacific. 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. Categorisation of cyclones aligns to the Australian Bureau of Meteorology (BoM) scale. It does not take a direct hit or a severe cyclone to cause significant damage or life-threatening weather.

Weekly statistical forecasts of TC genesis and TC activity for the SW Pacific basin are produced by MeteoFrance based on phasing of the MJO (Leroy and Wheeler, 2008). Cyclone season is November to May, but cyclones can occur at any time. 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. The spread for the estimated cyclone activity comes from the variation between five selected analogue seasons. Difference between expected and long-term average, SE SWP (Southern Cook Islands, Society Islands, Austral Islands), NE SWP (Northern Cook Islands, E Kiribati: Line Islands, Marquesas, Tuamotu Archipelago, Gambier Islands, Pitcairn Islands). Real-time MJO monitoring is also available from the Australian Bureau of Meteorology at http://www.bom.gov.au/climate/mjo/. The Severe Tropical Cyclone #Uesi is now a Category 3 system and looks fairly impressive on the satellite scans, with textbook outflow upper-level ventilation. It was expected to pass close to New Caledonia during the day and overnight on Tuesday, bringing squally rainfall, gusty winds, and rough seas. Tropical Cyclone Oma is predicted to produce heavy surf affecting the coasts of Australia, New Caledonia, and Vanuatu as of Monday, February 18. The system that was to become Cyclone Freda was first classified on … doi: 10.1002/joc.3753. A new island-scale tropical cyclone outlook for southwest Pacific nations and territories. An area of normal to above normal activity is indicated by some of the guidance about French Polynesia. The domain for the seasonal outlook encompasses a basin that is defined by climatological properties of TC occurrences rather than geopolitical or meteorological service administrative boundaries (Diamond et al., 2012). 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. Table 3: Previous analogue seasons and intensity of TCs that occurred in the Southwest Pacific during the November-April TC season . Most historic seasons used in the preparation of this outlook showed multiple ex-tropical cyclones passing within 550 km of the country. Near or above normal MSLP is predicted to the east of Fiji, particularly near and east of Samoa and American Samoa (Figure 7 & 8). What about cyclones in New Caledonia? 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. 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). Risk of TC occurrence is elevated for New Caledonia. The Noumea, New Caledonia tropical storm risk chart above shows the cyclone season. Atmospheric circulation patterns over French Polynesia and northern Australia indicate ENSO (El Niño-Southern Oscillation) conditions are indicative of the emergence of La Niña. The cyclone season in the Pacific is usually between October and May, but cyclones can occur at other times. Figure 9. Cyclone season in the region typically lasts from November to April but storms can occur outside this period. The main TC genesis region is expected to lie within a band between 10 – 12°S (northwest of Vanuatu) to the west of the International Date Line but shifted slightly west of normal. Tropical Cyclone Uesi recently formed near Vanuatu and is expected to near New Caledonia on Tuesday before it tracks south. People living in Fiji, New Zealand, Solomon Islands, New Caledonia, Vanuatu, Papua New Guinea, Tonga and other island nations in the Southwest Pacific will have more months to prepare for tropical cyclones, thanks to a new outlook model published in Scientific Reports. Collectively, this supports a near normal number of TCs (category 1 or higher) and at least a near normal amount of severe TCs (category 3 or higher) across the Southwest Pacific basin for the 2020/21 tropical cyclone season. 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. The highest cyclone frequency is found in the months from January to March. A category 3 cyclone has mean winds between 64-85 knots (118-157kmh) with a central pressure 970-945 hectopascals, Fiji's Meteorological Service states on its website. The ICU consensus column is based on the combined outcomes for the three aforementioned types of seasonal outlook information. NIWA’s Southwest Pacific Tropical Cyclone Outlook zeros in on New Caledonia as the focal point for TC genesis this season. The outcomes from this type of situation may include stronger ex-tropical cyclone impacts to northern New Zealand. Summers are wet and humid while the winters are dry. 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. Development of El Niño is highly unlikely. However, there is the potential for elevated activity near and west of the International Date Line (Vanuatu, New Caledonia, Coral Sea region) with normal or below normal activity to the east. 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. Category 5 strength cyclones, where sustained winds exceed 199 km/h, have occurred in some years (known as ‘analogue’ seasons) with similar conditions like what exists ahead of the 2020/21 season. This joint ENSO index is described in Gergis and Fowler (2005) as the “Coupled ENSO Index” (CEI). And cyclone risk was likely to be higher in regions around New Caledonia, Norfolk Island - and to the northwest of New Zealand. Renwick, 2013. In the 50 years since Cyclone … A majority of the historic analogues selected for the 2020/21 outlook (four out of five) indicate multiple severe TCs (at least three or more) that were equivalent to or greater than category 3 occurred in seasons similar to the present. evacuation orders). For Australia and associated offshore islands, please contact the Australian Bureau of Meteorology for information about how this guidance should be interpreted. Future work will evaluate (and validate) the outcome of each individual model vs the consensus-based approach. Near normal activity is expected for Tokelau, Fiji, Vanuatu, the Solomon Islands and Papua New Guinea. Mr Meke said Uesi was currently a category two cyclone with winds of up 95 … Cyclone level 2 alerts are in effect for the communes of Houaïlou, Kouaoua, Canala, Thio, Yaté, Ouvéa, Lifou, and Maré. Tag: New Caledonia cyclone Yasa . 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. Based on the guidance from the NIWA analogue method, a conservative range of 8-10 named TCs could be expected during the 2020/21 season for the Southwest Pacific basin (135° E – 120° W). People living in Fiji, New Zealand, Solomon Islands, New Caledonia, Vanuatu, Papua New Guinea, Tonga and other island nations in the Southwest Pacific will have more months to prepare for tropical cyclones, thanks to a new outlook model published in Scientific Reports. Even small tropical storms can develop into major cyclones causing extreme damage to infrastructure. Ensure you understand New Caledonia's cyclone alert system. The cooler than average equatorial SSTs, associated with La Niña, are forecast to be enveloped by warmer than average SSTs about much of the Southwest Pacific. However the south of the South Island is still assessing flood damage after widespread flooding caused by torrential rain last week. Cyclone Cook has formed over Vanuatu and is predicted to intensify to category three as it approaches New Caledonia on Monday. It's not yet clear whether any remnants of tropical cyclone Uesi will make it to New Zealand. Increased frequency and more intense TC activity can be expected during the MJO 6-7 paired phase (Diamond and Renwick, 2015). Track data are courtesy of International Best Tracks Archive for Climate Stewardship (IBTrACS). This can cut off communications and access to transportation, emergency assistance, medical care, and food and water. Cyclone Donna is forecast to pass over the northeastern islands of the New Caledonia archipelago late on Tuesday, May 9 (local time). On average, at least one ex-tropical cyclone passes within 550km of New Zealand each year. 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. 20 October 2020. There is very good agreement across the dynamical climate models with regard to forecast rainfall, air pressure, rainfall, and sea surface temperatures (SSTs) across the Southwest Pacific. Despite the risk reduction in some places, cyclones are still expected for countries that typically experience one or more named cyclones per year. Tropical Cyclone Uesi strengthened into a powerful storm system on Tuesday as it continued to batter New Caledonia with heavy rain and strong winds. The chart was processed from data supplied by the US Meteorological Agency (NOAA). The Accumulated Cyclone Energy, or ACE forecast:  ECMWF seasonal guidance indicates 80% (near normal amounts) of seasonal accumulated cyclone energy, a metric derived from tropical cyclone intensity and duration, across the basin as a whole. 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. Multi-model ensemble forecast air pressure anomaly (hPa), October-December 2020; red (blue) shades indicate above (below) normal air pressure; areas of below normal pressure in the tropics can indicate an increased potential for tropical cyclone genesis, Figure 8. TC tracks for past seasons similar to our expectations covered a wide region both east and west of and including the International Date Line (~165°E – 165°W) during extra-tropical transition (ETT) exiting the tropics at 25°S latitude (Diamond et al., 2013). There's been a mixed bag of weather across the country recently. Free phone within New Zealand: 0800 RING NIWA (0800 746 464), Copyright, NIWA. The average temperate hovers around 20-27 degrees Celsius year-round and there’s an average of 345 sunshine days annually. Cyclones can have a devastating impact. The historic tropical cyclones tracks selected for this outlook that passed close to New Zealand indicate a near equal probability of decaying ex-tropical cyclones tracking offshore to either the east or west of the North Island (see Figure 3). TCO-SP (University of Newcastle) deterministic model summary. Statistical prediction of weekly tropical cyclone activity in the Southern Hemisphere. Ensure you understand New Caledonia's cyclone alert system. safe cyclone holes in New Caledonia and try to get from locals and other cruisers precise directions on how to get into them. Our new tool, the Long-Range Tropical Cyclone Outlook for the Southwest Pacific , will assist forecasters and help local authorities to prepare for the coming season’s cyclone activity. Find out more about our data sources. The wage subsidy and retail: Which stores got it and who has paid it back. It would then be followed by another ridge of high pressure, just in time for the weekend. Wellington would also have a mostly fine week, with temperatures ranging between 19C-23C. New Caledonia Travel Seasons High Season (mid-December to end of January, July and August): From about 15 December to 30 January, and even more so around the Christmas/New Year period, the islands burst with families utilizing school holidays in Australia and New Zealand, and with French people escaping their wintry homeland. A synthesis of model atmospheric and SST guidance favour near average TC activity for the 2020/21 Southwest Pacific tropical cyclone season. The predicted track of Tropical Cyclone Uesi is towards New Caledonia. Steering winds are expected to be displaced south of normal, which may lead to reduced shear and increased retention of cyclone strength in the north Tasman Sea upon extra-tropical transition. The outlook suggests New Caledonia should prepare for stronger cyclone activity. For Uesi, I think the impact will be greatly affected by New Caledonia." That warm weather would mostly affect those in the North Island, as a cold front moves over the South Island on Thursday. For each year noted, that represents the start of the main development season (i.e. Multi-model ensemble forecast air pressure anomaly (hPa), January-March 2021; red (blue) shades indicate above (below) normal air pressure; areas of below normal pressure in the tropics can indicate an increased potential for tropical cyclone genesis, Information about the dynamical models used. 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. However, it is worth noting that the 2020 October-initialised guidance indicates more severe TC activity than the October-initialised guidance before each of the last three TC seasons. 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. For this season, elevated activity is expected for New Caledonia. Image (c) Fiji Met Service. Individuals present in New Caledonia are advised to monitor local weather reports and follow all instructions as issued by local authorities (e.g. MetService meteorologist Andrew James said Uesi was upgraded to a category 3 cyclone on Tuesday and was being monitored by Fiji's Meteorological Service. Humidity can become uncomfortable, but trade winds which blow for 250-300 days a year help temper this. Elevated risk of TC activity exists for New Caledonia, while normal activity is expected for  Vanuatu, Fiji, the Solomon Islands, Papua New Guinea and Tokelau (See Table 1 and Table 4; Figure 1, 2 & 3). 0–9. Tropical cyclone Uesi will near New Caledonia on Tuesday. This can cut off communications and access to transportation, emergency assistance, medical care, and food and water. Tropical cyclones have a significant impact across the Southwest Pacific, with the season officially starting in November and lasting until the end of April. Information on ECMWF model skill can be found here for: tropical cyclones, severe tropical cyclones, and ACE. 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. Early season TC activity is expected to be largely reduced, except near Fiji, and a potential start to cyclone activity may also occur close to or after the New Year. TCO-SP is a long-range tropical cyclone outlook based on a multi-variate statistical method generated using Poisson Regression (Magee et al., 2020) recently published in Scientific Reports. New Caledonia Cyclone Rona–Frank affected two thirds of New Caledonia's Grande Terre island between 20–21 February. Chappell, and J. Renwick, 2014. Most other islands to the east of the International Date Line are expected to have reduced TC risk for the season. They can cause landslides and flooding, and may disrupt essential services.
