Radio & TV Tonga, Nuku’alofa, 13/01/2020
The Tonga Meteorological Service has warned that the next 2 to 3 weeks could see 1 or 2 tropical cyclones develop over the South-west Pacific and could affect Tonga.
During every cyclone season there are active periods in which potential for tropical cyclone formation is increased. These active periods come around every 30 – 60 days on average and lasts for 2 to 3 weeks. The last active period of the cyclone season occurred between 21 December 2019 to the first week of January 2020, which saw Tropical Cyclone SARAI (Cat 1) cross between Tongatapu and Ha’apai on New Year’s Day. This next active period started today Monday 13th and should last until early February. An increasing Tropical Weather activity is brewing over the areas of the Solomon Islands and Vanuatu Regions. North of Vanuatu and East of the Solomon Islands is the area of where the next Tropical Cyclone is expected to develop from. Currently Tropical Depression 04F is located within this area and is expected to move east southeast and develop into a cyclone later in the week and could threaten Tongatapu by the weekend.
For Tonga this week, the weather will be very warm and humid with north to northwest winds early in the week and then will become more active with heavy rain and tropical system/cyclones development later in the week.
Tonga should prepare for a cyclone this week with an 85% chance of it becoming severe.
The Met Office also warned the public to stay tuned to the weather forecast on radio or on their website, and even on their Facebook page at Tonga Met Office.
