At noon on November 20th, Mr. Hoang Phuc Lam, Deputy Director of the National Center for Meteorological and Hydrological Forecasting (Department of Meteorology and Hydrology, Ministry of Agriculture and Environment ), provided information on the situation and trends of rain and floods in Central Vietnam.
According to Mr. Hoang Phuc Lam, on the night of November 19th and the morning of November 20th, the flood level on the Ky Lo River ( Dak Lak ) exceeded the historical flood peak of 2009, the flood level on the Ba River (Dak Lak) exceeded the historical flood peak of 1993, and the Dinh - Ninh Hoa River (Khanh Hoa) exceeded the historical flood peak of 1986.
Currently, flood levels on the Kon River, Ky Lo River, Ba River, Dinh River - Ninh Hoa, Cai River Nha Trang, and Cai River Phan Rang remain very high, approximately 0.2 - 2.12m above alarm level 3; flood levels on the Krong Ana and Srepok rivers (Dak Lak) are below alarm level 3.
Assessing the recent floods, Mr. Hoang Phuc Lam stated that this period of rain has lasted for many days in the South Central region (from around the night of November 17th until now), following consecutive heavy rains in October and early November.
Due to the impact of cold air and easterly wind disturbances, some areas experienced extreme rainfall in a short period, for example, Son Thanh Tay and Son Thanh Dong, Hoa My Tay, Son Long, Son Dinh, Song Hinh… recorded rainfall amounts of up to 1,000 - 1,200mm.
According to representatives from the National Center for Meteorological and Hydrological Forecasting, from November 20th to the night of November 21st, rain is expected to concentrate in the eastern part of Dak Lak province and the northern part of Khanh Hoa province, with rainfall generally ranging from 100-200mm, and in some localized areas exceeding 350mm. Therefore, the risk of flash floods and landslides in coastal areas and the South Central Highlands remains very high.
According to the Deputy Director of the National Center for Meteorological and Hydrological Forecasting, floodwaters are receding on most rivers in the South Central region, except for the Dinh - Ninh Hoa River, the Cai Phan Rang River (Khanh Hoa), and the Krong Ana River (Dak Lak), which are still rising.
After November 21st, rainfall in Dak Lak and Khanh Hoa provinces will decrease, and flood levels on rivers in these areas will recede rapidly. However, widespread flooding in Gia Lai, Dak Lak, and Khanh Hoa provinces will continue even after the rain and floods subside. At the same time, rainfall in Central Vietnam has not ended; after November 21st, it will shift northward from the current flood zone, with the heaviest rainfall concentrated in Quang Ngai, Da Nang, and Hue.
