The year 2025 is recorded as a year with extremely unusual and unusual natural disasters, causing serious damage across the country. 2025 is the year of the most unusual natural disasters in history. According to the World Meteorological Organization, the year 2025 has witnessed many records of hydro-meteorological disasters being recorded. Around the world, many records of highest temperatures in many places were recorded exceeding 48oC, setting a new record for the number of days. consecutively have maximum temperatures (United States, Turkiye, July 2025). The year 2025 also recorded 10 major storms (level 3 or higher), surpassing previous records. The phenomenon of storms rapidly increasing in intensity has become common, super storm Phoenix in the Northwest Pacific has increased from level 1 to level 5 (wind speed over 250 km/h in just 24 hours (September 2025). In addition, many floods, inundations and flash floods were also recorded, especially extremely serious floods and landslides such as in Sumatra, Indonesia (December 11, 2025) causing over 700 people to die and hundreds missing, Pakistan (June 6, 2025) causing more than 1,000 deaths... Notably, Bach Ma station (Vietnam) recorded extreme rainfall of up to 1,739 mm in just 24 hours (October 2025). The World Meteorological Organization is confirming that this is one of the largest known 24-hour rain events in the world. In Vietnam, 2025 is recorded as a year with extremely unusual and unusual natural disasters, causing serious damage across the country. By the end of November 2025, there were 21 storms/tropical storms (15 storms, 6 tropical storms) operating in the East Sea and 2025 became the year. There are the highest number of active storms/NWs in the East Sea since monitoring data has been available (since 1961). Previously, the year with the most was 2017 with 20 storms/NWs (16 storms, 4 NSDs). In addition to the record number of storms/NWs, the 2025 storm season also recorded some special, unusual and extreme characteristics such as: Storm No. 1 (WUTIP) is the first storm to appear. appeared in the East Sea in June after more than 40 years. Storm No. 9 (RAGASA) with intensity level 17, gusts above level 17, became the strongest storm ever active in the East Sea region; tropical storm at the end of November, originating from storm Senyar moving from the Indian Ocean to the Northwest Pacific region (in the past there have been tropical depressions or storms moving from the West Pacific to the Indian Ocean, but not in the opposite direction. ever recorded in meteorological history). In 2025, serious floods occurred on a large scale, with flood peak water levels on rivers exceeding historical milestones in the North, the Central region, the Central Highlands, and the lower Mekong River. In no year has a particularly large flood been recorded, historic floods have appeared in 20 rivers in the same year such as Cau River (Thai Nguyen, Bac Ninh), Thuong River (Bac Ninh), Chung River (Lang Son), and Long River. Bang Giang (Cao Bang), Lo River (Tuyen Quang), Ngoi Hut River, Ngoi Thia (Lao Cai), upper Ma River and Buoi River, Yen River (Thanh Hoa), upper Ca River (Nghe An), Bo River (Hue City), Vu Gia-Thu Bon River (Da Nang), Ky Lo River, Ba River (Dak Lak), Dinh Ninh Hoa River (Khanh Hoa), Luy River (Lam Dong), lower Tien River (Vinh Long, Dong Thap), lower Hau River (An Giang, Can Tho). Particularly serious is the historic flood in Phu Yen (now the eastern region of Dak Lak province), which is considered to surpass the historic flood peak of 1993 in the Ba River basin. According to Mr. Hoang Duc Cuong, Deputy Director of the Department of Hydrometeorology, Ministry of Agriculture and Environment, unusual storm activity, severe and unusually large floods will occur in 2025 in Vietnam. as well as in the world is a clear proof that traditional flood laws are changing, reflecting the trend of increasingly extreme and unpredictable weather due to the impact of climate change. Forecasting natural disasters in the last months of 2025 and early 2026 According to the National Center for Hydro-Meteorological Forecasting, from December 2025 to February 2026, ENSO will likely continue to maintain a La Nina state, then from December 2025 to February 2026. From 3 to 5/2026, ENSO is likely to return to a neutral state in December 2025. There is a possibility of 1-2 storms/tropical storms appearing in the East Sea area from January to May 2026. Currently, there is a tropical depression located at about 14 degrees. North latitude -135 degrees East longitude, moving slowly in the north-northwest direction. It is forecast that around December 6-7, this tropical depression is likely to cross the central region of the Philippines and enter the East Sea, potentially intensifying into a storm (storm No. 16). The storm is likely to directly affect the mainland in the Central and South Central regions, causing a period of moderate and heavy rain in the provinces from Hue city to the Khanh Hoa area December 2025 in the Central and South Central regions is likely to have 1-2 periods of moderate and heavy rain on a large scale, in which the rainfall in the region will range from N.Quang Tri flood waters and the northern region of the South Central Coast tend to be higher than the average for many years. It is necessary to guard against the risk of flash floods and landslides. In December 2025, cold air will continue to increase in frequency and intensity and there may be severe and harmful cold in the North, but concentrated in the northern mountainous areas. Cold air continues to be strong in January and February 2026, causing severe and harmful cold spells. The Southern region is likely to experience hot weather from around the beginning of March 2026 in the Southeas
