The National Center for Hydro-Meteorological Forecasting (NCHMF) reported that on the afternoon of 18/11, a cold front had affected most of the Northern region, bringing rain. Strong winds were observed at sea, with gusts reaching level 9 (Beaufort scale) at Bach Long Vi, level 7 at Hon Ngu, and level 8 at Ly Son.
The cold front is expected to continue expanding its influence across the Northern region tonight and tomorrow night. During this cold spell, the lowest temperatures in the northern plains are forecast to be 12-15 degrees C, while mountainous and midland areas will experience 9-12 degrees C, with some high mountain areas dropping below 5 degrees C.
US-based Accuweather forecasts that Hanoi's temperature on 19/11 will decrease to 13-17 degrees C, then gradually rise to 15-24 degrees C by the weekend. High-altitude locations above 1,500 m, such as Sa Pa (Lao Cai), will see the lowest temperatures of this spell tomorrow, ranging from 5-11 degrees C, before increasing to 7-16 degrees C.

The Central region is also experiencing the effects of the cold front. On the night of 18/11 and throughout 19/11, the lowest temperatures in the North Central region are generally 12-15 degrees C, with mountainous and midland areas at 9-12 degrees C, and high mountain areas dropping below 5 degrees C. Provinces from Quang Tri to Hue will see temperatures around 19-21 degrees C on 19/11, falling to 17-19 degrees C on 20/11.
The cold front, combined with an eastern wind disturbance, will continue to bring rain to Central Vietnam. Forecasts for the night of 18/11 indicate that Hue City, Da Nang, the eastern parts of provinces from Quang Ngai to Dak Lak, and northern Khanh Hoa will receive 60-130 mm of rain, with localized areas experiencing over 250 mm. Ha Tinh, Quang Tri, and southern Khanh Hoa are expected to see 30-70 mm of rain, with localized amounts exceeding 150 mm.
From 19/11 to 20/11, Da Nang, the eastern parts of provinces from Quang Ngai to Dak Lak, and northern Khanh Hoa are predicted to receive 100-200 mm of rain, with localized amounts exceeding 300 mm. Thua Thien Hue and southern Khanh Hoa will see 30-70 mm of rain, with localized areas receiving over 150 mm.
Beyond the cold temperatures and heavy rainfall, the cold front will continue to generate strong winds. The Gulf of Tonkin will experience winds of level 7-8, gusting to level 9-10, with waves reaching 3-5 m. The North East Sea (including the Hoang Sa archipelago) will see winds of level 7-8, gusting to level 9-10, and waves 4-6 m high. Coastal areas from Quang Tri to Quang Ngai and the northern part of the central East Sea will have strong winds of level 6-7, gusting to level 8-9, with waves 4-6 m high. Winds in the sea region from Gia Lai to Ho Chi Minh City will gradually strengthen to level 6, gusting to level 7-8, with waves 3-5 m high.
The cold and severe cold conditions are likely to impact livestock, poultry, and crop growth and development. Heavy rainfall may lead to flooding in low-lying areas, flash floods in small rivers and streams, and landslides on slopes. Intense rainfall over a short period can also cause inundation in urban and industrial zones.
