The meteorological agency has issued a level-4 natural disaster risk warning (a very high level, just below the most severe level 5) for the western part of the central East Sea and coastal areas from Quang Ngai to Dak Lak, including Ly Son island; and for inland areas from Quang Ngai to Gia Lai.

A level-3 warning has been issued for the sea from southern Quang Tri to Da Nang (including Cu Lao Cham island) and Khanh Hoa, as well as inland areas from southern Quang Tri to Da Nang, eastern Dak Lak, and northern Khanh Hoa.

By late afternoon, the level-4 disaster warning is expected to be in effect in the sea areas from Quang Ngai to Dak Lak (including Ly Son island) and inland regions from Quang Ngai to Gia Lai.

A level-3 alert also applies to the sea from southern Quang Tri to Da Nang, Cu Lao Cham island, and Khanh Hoa; as well as inland areas including southern Quang Tri to Da Nang, western Quang Ngai and Gia Lai, eastern Dak Lak, and northern Khanh Hoa.

Kalmaegi is considered the strongest storm to hit Vietnam so far in 2025, with a vast area experiencing winds above level 6, stretching from southern Quang Tri to northern Khanh Hoa.

At 7 p.m. today, when the storm center reaches the coastal area between Quang Ngai and Dak Lak, wind strength is expected to remain at levels 13-14 with gusts up to level 17. Even when it penetrates deep inland, nearing the Vietnam-Laos border by early morning November 7, it may still sustain level 9 winds with gusts reaching level 11.

Starting this evening, winds will strengthen to levels 6-7 in areas from southern Da Nang to Dak Lak, increasing to levels 8-9. Regions near the storm’s path, especially the eastern areas of Quang Ngai and Gia Lai, could experience levels 10-12 winds with gusts up to level 14-15.

From southern Quang Tri to northern Da Nang and northern Khanh Hoa, winds are expected to rise to levels 6-7, with gusts at levels 8-9. The strongest wind period will be from tonight until early morning tomorrow.

At the same time, strong winds of levels 6-7 will also impact the western regions of Quang Ngai to Gia Lai, with gusts at levels 8-9 near the storm's path and gusts up to level 11.

Mai Van Khiem, Director of the National Center for Hydro-Meteorological Forecasting, warned: “We consider this a particularly dangerous storm with very strong intensity over the East Sea. Even after reaching land, it could still maintain destructive wind speeds from the evening through the night of November 6.”

The typhoon's circulation is also causing widespread heavy rainfall in the central and south-central regions. Rainfall from Da Nang to Dak Lak is expected to range from 200 to 400 mm, with some areas exceeding 600 mm between November 6 and 7.

From southern Quang Tri to Hue, and in Khanh Hoa and Lam Dong, rainfall is expected to be between 150 and 300 mm, with isolated areas experiencing more than 450 mm. The rain is expected to ease from November 8.

From Thanh Hoa to northern Quang Tri, moderate to heavy rain is forecast on November 7-8, with totals ranging from 50 to 150 mm, and some areas seeing over 200 mm.

Experts also warned that the combination of short-duration heavy rainfall and already high water levels in river systems increases the risk of flooding across many regions.

Provinces under flood alerts include Dak Lak, Gia Lai, Quang Ngai, Da Nang, and Hue. Water levels in some rivers could surpass alarm levels 2 to 3, with some locations exceeding level 3.

Mountainous regions, especially in the western part of central Vietnam and the Central Highlands, face a high risk of flash floods and landslides.
