The National Center for Hydro-Meteorological Forecasting (NCHMF) reported that after about seven hours impacting Mong Cai (Quang Ninh), typhoon Maysak entered southern Guangxi, China, at 2:00 AM today. It had maximum sustained winds of 74 km/h, category 8, with gusts of category 10.
The typhoon is moving north-northeast, penetrating deeper into Guangxi province. As of 10:00 AM today, the typhoon's center remained over Guangxi, 120 km from Mong Cai (Quang Ninh), with winds of about 74 km/h, category 8, and a speed of 5-10 km/h. Forecasts indicate that this afternoon, Maysak will weaken into a tropical depression and then a low-pressure area over Guangxi.
Compared to typhoons in 2025, Maysak is a weak typhoon, making landfall in Mong Cai at category 8-9, which is only one to two categories above a tropical depression. Typically, weak typhoons weaken rapidly upon hitting land, but Maysak maintained category 8-9 for sixteen hours, from 8:00 PM last night until now.

The typhoon brought heavy rain to the Northeast region, including Lang Son, Bac Ninh, Hai Phong, and Quang Ninh. The NCHMF reported that from 7:00 PM on 4/7 to 8:00 AM on 5/7, Mong Cai received 275 mm of rain, the highest nationwide. Nam Pam (Son La) recorded 250 mm, and Kim Noi 1 (Lao Cai) received 146 mm.
For 5/7, the Northeast region is expected to continue experiencing widespread rain of 20-50 mm, with localized areas receiving over 100 mm. Lai Chau, Dien Bien, Son La, and Lao Cai will see 30-60 mm of rain, with some places exceeding 150 mm. The weather agency warns of intense rainfall, potentially over 100 mm in three hours, which could lead to localized flooding, flash floods, and landslides.
Rivers in the Northeast region are likely to experience a flood surge, with water levels in the upstream areas rising 3-6 m and downstream areas increasing 2-4 m. The upstream Lo River, the Thai Binh river system, and rivers in Bac Ninh could reach alert level one-two. Rivers in Quang Ninh, Lang Son, and Cao Bang may reach alert level two-three, with some locations potentially exceeding alert level three.

The NCHMF also issued a warning for flash floods and landslides over the next six hours in many mountainous areas of Lai Chau, Dien Bien, Son La, Lao Cai, and Quang Ninh. Dozens of communes, wards, and special zones are identified as being at risk of flash floods on small rivers and streams, landslides on steep slopes, and localized flooding in low-lying areas due to intense rainfall.
This morning, the National Steering Committee for Civil Defense issued a dispatch requesting Tuyen Quang, Phu Tho, Cao Bang, Lang Son, Quang Ninh, Thai Nguyen, Hanoi, and Bac Ninh to closely monitor flood developments and promptly inform residents in dangerous areas. Local authorities are to review and prepare to evacuate residents in areas along rivers and streams, and in low-lying regions.
According to the Vietnam Disaster Management Authority (VDMA), as of 6:00 AM on 5/7, Maysak's circulation had caused 30 houses to lose their roofs and damaged about 600 ha of aquaculture. Strong winds also broke 850 trees. Four anchored boats broke free and drifted but were safely rescued. Additionally, the gate of Mui Ngoc Border Control Post collapsed, two oto were damaged by a collapsed wall, and one oto was submerged.
