HANOI: Typhoon Matmo is moving north-northwest with a maximum sustained wind speed of 133km/h with level-15 gusts (167-183km/h).
As of 4pm on Saturday (Oct 4), the storm is approximately 290km northeast of Hoang Sa Special Administrative Zone (Spratly Islands). It is the 11th storm to enter the East Sea this year.
According to the National Centre for Hydro-Meteorological Forecasting (NCHMF), Matmo is likely to make landfall in the area between Quang Ninh Province and Guangxi (China) around Monday (Oct 6) afternoon.
“Typhoon Matmo has a wide circulation, so even before it makes landfall or has a direct impact, it can still induce thunderstorms which could significantly affect residents and properties, particularly in the Gulf of Tonkin and across the northern region,” said the NCHMF’shead of weather forecasting department Nguyen Van Huong.
Heavy rainfall is expected in the northern mountains and midlands from Sunday night until Tuesday, with rainfall totals ranging from 150-250mm, and some areas exceeding 400mm.
The northern delta region to Thanh Hoa Province are forecast to have moderate to heavy rain.
Hanoi is unlikely to experience strong winds from the typhoon but can expect downpours from early Monday morning until Tuesday night.
Explaining the typhoon’s intensification upon entering the East Sea (internationally known as the South China Sea), Huong noted that the storm encountered relatively favourable conditions during its movement.
The current sea surface temperature in the East Sea is around 28-29 Celsius degrees, which is more conducive to storm intensification compared to the average threshold of 26-27 degrees Celsius.
Additionally, the low wind shear at sea allowed moisture to accumulate, contributing to the storm’s structural development.
Matmo is expected to strengthen over the next 24 hours.
However, as it moves past the northern part of China’s Leizhou Peninsula and enters the Gulf of Tonkin, increased land friction and higher wind shear in the region is forecast to weaken the storm. - Vietnam News/ANN
