Parts of northern Vietnam brace for heavy rainfall above 250mm

The National Center for Hydro-Meteorological Forecasting said provinces including Thai Nguyen, Tuyen Quang, Phu Tho, Lao Cai, Lai Chau, Dien Bien, and Son La will possibly see rainfall of 30-70 mm, with localized downpours exceeding 150 mm.

Precipitation in other northern provinces may reach 20-40 mm, with rainfall in some areas surpassing 70 mm.

On Tuesday night, the same provinces are forecast to receive an additional 20-50 mm, with localized totals above 100 mm.

Overall, rainfall across northern midland and mountainous provinces between late Monday and late Tuesday could reach 50-120 mm, with isolated areas exceeding 250 mm.

The national weather agency cautioned that intense rainfall of more than 100 mm within three hours may cause flooding in urban and low-lying areas, flash floods in small rivers and streams, and landslides in mountainous terrain.

In response to upcoming downpours, the National Civil Defense Steering Committee has urged northern midland and mountainous provinces to mobilize forces for recovery from recent flash floods, evacuate residents from vulnerable areas, and ensure safety at mines, construction sites, and reservoirs, particularly small hydropower and irrigation dams.

In related news, storm Noul, the second storm to affect the East Vietnam Sea this year, was located inland in southern Guangdong, China at 4:00 pm on Sunday, with maximum winds of 62-74 kph and gusts up to 89-102 kph.

The storm is expected to weaken into a tropical depression and then a low-pressure zone, with no direct impact on Vietnam.
