On the afternoon of Aug. 26, Storm Narra, the fourth storm to affect Vietnam this year, dissipated over mainland China after lingering over the Gulf of Tonkin for several days.

According to Vietnam’s National Center for Hydro-Meteorological Forecasting (NCHMF), at 1 p.m. the low-pressure area was over southwestern Guangdong province, China. Maximum winds near its center had fallen below force 6, or 39 kph.

Over the next 12 hours, the low-pressure area is forecast to move mainly north-northeast, continuing to weaken before dissipating completely. This was the weather agency’s final bulletin on Storm Narra.

The agency said that after days of widespread heavy rain caused by the storm, rainfall across northern Vietnam is gradually easing, although localized showers and thunderstorms remain possible.

From the evening of Aug. 26 through Aug. 27, the northern mountainous and midland regions are forecast to receive scattered rain, moderate showers and thunderstorms, with rainfall generally ranging from 20-40mm and exceeding 80mm in some locations.

The northern delta and Thanh Hoa province are expected to see scattered showers and thunderstorms, with rainfall of 10-30mm and localized totals above 60mm.

Northern Vietnam could see heavy rain at the end of August

According to the weather agency’s extended outlook, northern Vietnam and Thanh Hoa are expected to continue experiencing scattered showers and thunderstorms from the night of Aug. 28 through Sept. 5, with heavy rain possible in some areas.

Of particular concern is the period from the night of Aug. 29 through Aug. 31, when the region could see rain, moderate showers and thunderstorms, with localized heavy to very heavy rainfall.

From around Sept. 2, rainfall across the north is expected to ease, with only isolated showers and thunderstorms remaining.

In Hanoi, Aug. 29 is forecast to bring intermittent sunshine. From the night of Aug. 29 through Sept. 1, showers and widespread thunderstorms are expected, with locally heavy rain. Sept. 2 should be sunny and dry at night. Temperatures are forecast to range from lows of 24-27 degrees Celsius to highs of 30-33 degrees, dipping slightly to 28-31 degrees between Aug. 30 and Sept. 1.

In Nghe An and Ha Tinh provinces, rain, moderate showers and thunderstorms are possible from the night of Aug. 30 through Sept. 1, with localized heavy to very heavy rainfall. Conditions are expected to gradually improve afterward.

From the night of Aug. 28 through Sept. 5, the heat in these areas is likely to persist until around Aug. 30 before gradually easing.

Meanwhile, the Central Highlands and southern Vietnam will see isolated showers and thunderstorms. Rain and thunderstorms are expected to become more scattered during the late afternoon and evening, with locally heavy downpours.

Weather forecasters warned that thunderstorms could bring tornadoes, lightning, hail and strong wind gusts. People in mountainous areas should remain alert to the risks of flash floods, landslides and localized flooding during intense downpours.
