From the morning of July 4th through the end of July 5th, Vietnam’s Northeast region and Thanh Hoa province are bracing for intense rainfall, with widespread precipitation expected to range between 100–200mm. The Northeast region, in particular, is forecast to receive 200–300mm, while localized areas may surpass 500mm. A high-intensity rainfall warning (exceeding 100mm/3h) has been issued for these regions.
Several areas are currently experiencing heavy rainfall as Typhoon No. 1 makes landfall.
As of 9 AM today, the center of Typhoon No. 1 was located at approximately 20.2°N latitude and 108.1°E longitude, roughly 40km east of Bach Long Vy (Hai Phong) and 145km southeast of Mong Cai (Quang Ninh). The storm is carrying winds of level 8–9 (62–88 km/h), with gusts reaching up to level 11. Over the next 3 hours, the typhoon is projected to move northwest at a speed of approximately 15 km/h.
According to Mr. Hoang Phuc Lam, Deputy Director of the National Center for Hydro-Meteorological Forecasting, at 7 AM today (July 4th), Typhoon No. 1 was positioned about 170km south-southeast of Mong Cai (Quang Ninh) and 70km east of Bach Long Vy.
“Over the next 4–5 hours, the typhoon’s circulation is expected to approach the mainland in the Quang Ninh–Hai Phong area. Beginning around noon today, coastal areas of Quang Ninh–Hai Phong will face strong winds at level 5, escalating to level 6, with level 7–8 winds near the typhoon’s center and gusts up to level 9–10. Rain will start this morning in Quang Ninh–Hai Phong, intensifying to heavy to very heavy rain by this afternoon and evening,” Mr. Lam explained.
Mr. Hoang Phuc Lam identified three primary risks associated with this typhoon. The Northeast region and Thanh Hoa should remain alert for heavy rain, thunderstorms, tornadoes, flash floods, and landslides.
From the morning of July 4th to the end of July 5th, heavy to very heavy rain is anticipated, with widespread precipitation of 100–200mm. The Northeast region will bear the brunt with 200–300mm, and localized areas may exceed 500mm. The heaviest rainfall is expected in Lang Son, Quang Ninh, Hai Phong, and Bac Ninh.
Prolonged heavy rain, combined with intense thunderstorms, increases the risk of urban flooding, flash floods in mountainous areas, and landslides, potentially disrupting transportation, production, and daily life.
Sea conditions will be extremely rough, posing significant dangers to maritime activities. The affected area includes the Gulf of Tonkin, encompassing Bach Long Vy, Van Don, Co To, Cat Hai, and Hon Dau Island. Strong winds of level 6–7 are expected, with level 8–9 winds near the typhoon’s center and gusts up to level 11. Sea waves will reach 2–4.5m, and the sea will be highly turbulent.
Coastal areas of Quang Ninh, Hai Phong, and Hung Yen will also face strong winds. From the afternoon of July 4th, winds will strengthen to level 6, with level 7–8 winds near the typhoon’s center and gusts up to level 9–10. Sea waves will be 2–3.5m high, accompanied by a storm surge of 0.2–0.4m.
“While current forecasts indicate the typhoon is unlikely to penetrate deep into the mainland, its circulation can still significantly impact the sea, coastal areas, and the Northeast region. Thunderstorms, tornadoes, lightning, and strong gusts may occur before, during, and after the typhoon passes, potentially damaging homes, trees, power systems, infrastructure, and disrupting outdoor activities,” Mr. Lam warned the public.
Additionally, on July 4th, areas from Nghe An to Quang Tri will experience showers and scattered thunderstorms with rainfall of 15–30mm, and localized heavy to very heavy rain exceeding 100mm. The Central Highlands and Southern regions will see scattered showers and thunderstorms with rainfall of 10–30mm, and localized heavy rain exceeding 70mm. Thunderstorms may bring tornadoes, lightning, hail, and strong gusts. From the evening of July 5th, heavy rain in the Northeast region and Thanh Hoa will gradually subside. The risk level for natural disasters due to heavy rain, tornadoes, lightning, and hail remains at level 1.
