According to Mr. Mai Van Khiem - Director of the National Center for Hydro-Meteorological Forecasting, Department of Hydro-Meteorology, last night, November 1, the tropical depression in the eastern area of the Philippines strengthened into a storm - the 25th storm in the Northwest Pacific region, with the international name Kalmaegi. At 7:00 a.m. on November 2, storm Kalmaegi was at about 11 degrees north latitude - 134.4 degrees east longitude, level 9 intensity.
"It is forecasted that around November 5, the storm will enter the East Sea and become storm No. 13. The strongest storm intensity when moving to the Truong Sa special zone can be above level 12, gusting above level 15; then it will likely move towards the Central provinces" - Mr. Khiem said.
Previously, the meteorological agency said that initial forecasts showed that if it entered the East Sea, this could be a strong storm.
Around November 7, the storm is likely to move into our mainland. The key area to note that it is likely to be directly affected is from Da Nang city to Khanh Hoa.
The storm may cause strong winds and heavy rain in the provinces of the Central Central, South Central and Central Highlands regions from the night of November 6 to November 9, 2025.
A representative of the meteorological agency noted that currently, the storm has not entered the East Sea, and is still affected by many large-scale factors in the coming days as well as the terrain when making landfall in the Philippines.
Therefore, scenarios on intensity, direction of movement as well as areas directly affected by storm No. 13 still need to be monitored and updated further through new monitoring and forecasting data.
The National Center for Hydro-Meteorological Forecasting said that in November, storms/tropical depressions and storm-related rain will continue to be notable weather patterns.
According to the average data of many years in November, there were 1.5 storms or tropical depressions in the East Sea, 0.9 of which made landfall in Vietnam.
This November, the possibility of storm and tropical depression activity is higher than average. It is forecasted that there will be 2-3 storms or tropical depressions in the East Sea and 1-2 storms will likely affect the mainland of Vietnam.
Previously, in October, there were 2 storms and 1 tropical depression in the East Sea. In particular, both storms, storm No. 11 Matmo and storm No. 12 Fengshen, directly affected our mainland.
Data analyzed from the meteorological agency also shows that in November, the total rainfall in the Northern, Thanh Hoa and Southern regions will generally be approximately the same as the average of many years in the Northwest region, 10 - 30% lower than the average of many years. The remaining areas across the country have total rainfall generally 10 - 25% higher than the average of many years, especially the area south of Quang Tri to Dak Lak has the possibility of total rainfall 25 - 40% higher than the average of many years in the same period.
From now until the first half of December 2025, moderate and heavy rains are likely to continue to appear in the Central region, concentrated in the area from Ha Tinh to Da Nang, Khanh Hoa and the eastern areas of the provinces from Quang Ngai to Dak Lak.
The western part of Lam Dong province and the Southern region in November are likely to have many days of showers and thunderstorms; in which, some days may have moderate to heavy rain.
