Hanoi (VNA) - The tropical depression, which had weakened from Typhoon Kalmaegi - the 13th storm hitting the East Sea this year, has downgraded into a low-pressure area over southern Laos, on November 7 early morning, according to the National Centre for Hydro-Meteorological Forecasting (NCHMF).
At 4:00 am, the centre of the low-pressure area was located near 14.6 degrees North latitude and 106.8 degrees East longitude, with maximum winds below level 6 (below 39km per hour).
In the next 12 hours, it is forecast to continue moving west-northwestward and gradually dissipate.
Earlier, at night of November 6, the storm weakened into a tropical depression.
Moderate to heavy rainfall, with localised downpours of over 80mm and an average of 20-50mm, is expected from southern Quang Tri to Da Nang and across the Central Highlands region until November 11 morning, while areas from Thanh Hoa to northern Quang Tri will experience heavy rain, with some places seeing heavy rainfall ranging from 50-150mm, and locally over 200mm, from November 7 to 8. Rainfall intensity may exceed 100mm per hour in certain areas.
In addition, scattered showers and thunderstorms are expected across the southern region in the evening and night of November 7, with rainfall ranging from 10-30mm, and locally over 70mm in some areas.
Vu Anh Tuan, Deputy Head of the centre's Weather Forecast Departmen, warned that thunderstorms may bring tornadoes, lightning, hail, and strong gusts. Heavy rainfall could lead to flooding in low-lying, urban, and industrial areas, as well as flash floods in small rivers and streams, and landslides on steep slopes.
At sea, on November 7, the southern part of the Gulf of Tonkin will experience winds of level 6, gusting to levels 7-8, with rough seas and waves 2.5-3.5 metres high.
In waters from the south of Da Nang to Gia Lai, winds will reach level 5, occasionally level 6, with gusts up to levels 7-8, causing rough seas and waves of 2-3 metres. Winds will gradually weaken at night.
Additionally, scattered showers and thunderstorms are expected in the northern part of the East Sea, in waters from Lam Dong to Ca Mau, Ca Mau to An Giang, and in the Gulf of Thailand on November 7. Thunderstorms may bring tornadoes, strong gusts of level 6-7, and waves exceeding 2 metres.
All vessels operating in these above-mentioned areas face a high risk from strong winds and high waves./.
