Although the storm's center has moved out of the country, its circulation continues to bring heavy to very heavy rainfall across the Northeastern region, with a high risk of flooding, flash floods, and landslides.
At 5 a.m. on July 5, the center of typhoon Maysak had moved into southern Guangxi Province, China, about 63 kilometers north of Mong Cai. Maximum sustained winds near the storm's center were at level 8 (62–74 km/h), with gusts reaching level 10 (89–102 km/h). The storm was moving north-northeast at a speed of 5–10 kilometers per hour.
The National Center for Hydro-Meteorological Forecasting forecasts that typhoon Maysak will continue to weaken into a tropical depression in the coming hours before degenerating into a low-pressure area.
At around 10 p.m. on July 4, typhoon Maysak made landfall in the Mong Cai area of Quang Ninh Province. After affecting Quang Ninh's coastal areas for more than two hours, the storm reached its peak intensity over land, with maximum sustained winds of level 9 (75–88 km/h) and gusts up to level 11 (103–117 km/h).
Under the direct influence of the storm's circulation, strong winds were recorded across Quang Ninh Province and the northern Gulf of Tonkin. Mong Cai experienced winds of level 9 with gusts reaching level 12 (118 - 133 km/h); Bach Long Vi recorded winds of level 9 with gusts up to level 11; Co To saw level-8 winds with gusts reaching level 10, accompanied by waves of up to 2.25 meters. Cua Ong and Quang Ha both recorded level 8 winds with gusts up to level 9.
From the afternoon of July 4 to the morning of July 5, Quang Ninh experienced heavy to very heavy rainfall. Mong Cai recorded 247.6 millimeters of rainfall during the period.
The National Center for Hydro-Meteorological Forecasting warned that although the center of the storm has moved out of the country, its circulation will continue to bring winds of levels 6 (39–49 km/h)–7 (50–61 km/h) with gusts up to level 8 to northeastern Quang Ninh Province.
During the morning and around midday on July 5, the northern Gulf of Tonkin, including Bach Long Vi, Van Don, Co To, and Cat Hai, is expected to experience winds of levels 6–7 with gusts reaching levels 9–10. Sea waves are forecast to reach 2–3 meters, with rough sea conditions. Along the coast of Quang Ninh Province, winds of levels 6–7 with gusts up to level 8 will persist before gradually weakening after 10 a.m.
Regarding rainfall, from the early morning through the end of July 5, the Northern region is expected to continue experiencing moderate to heavy rain, with widespread accumulations of 40–90 millimeters and isolated totals exceeding 120 millimeters. The Northeast is forecast to receive heavy to very heavy rainfall, with widespread accumulations of 100–200 millimeters and some areas expected to record more than 300 millimeters.
The meteorological agency warned that the risk of natural disasters associated with the storm's circulation remains high. Heavy rainfall could trigger flooding in urban areas, industrial parks, and low-lying areas while also increasing the risk of rising water levels on small rivers and streams, flash floods, and landslides in mountainous areas, particularly across the Northeastern provinces.
Residents and local authorities are advised to monitor weather forecasts closely and remain vigilant until rainfall and strong winds have completely subsided.
