The National Center for Hydro-Meteorological Forecasting announced that a low-pressure vortex, active at an altitude of 1,500-5,000 meters, continues to influence the weather across Northern Vietnam. From tonight until the end of 20/7, the midland and mountainous areas of the North, along with Quang Ninh, are forecast to receive widespread rainfall of 40-80 mm, with some localized areas experiencing over 200 mm.

As the low-pressure vortex weakens and dissipates from 21/7 to 24/7, rainfall in Northern Vietnam will decrease in both area and volume. However, around 24-25/7, the activation of a humid southeast wind is expected to bring an increase in thunderstorms across many localities.

The meteorological agency issued a warning that intense, short-duration rainfall could lead to localized flooding in low-lying and urban areas. This also increases the risk of flash floods and landslides in mountainous regions.

Accuweather, a US-based weather service, forecasts temperatures in Hanoi next week to range from 27-34 degrees Celsius. High-altitude areas above 1,500 meters, such as Sa Pa in Lao Cai, will see temperatures between 17-25 degrees Celsius early in the week, dropping to 18-21 degrees Celsius by the weekend.

In Central Vietnam, from 20/7 to 21/7, the area from southern Nghe An to Da Nang, and the eastern parts of Quang Ngai to Dak Lak provinces, will continue to experience hot weather, with some areas facing intense heat. Maximum temperatures are expected to be between 35-37 degrees Celsius, with some locations exceeding 38 degrees Celsius, accompanied by humidity levels of 45-55%.

The heat will gradually subside starting 22/7, becoming localized by approximately 23/7. From 24/7 to 26/7, this region is expected to have scattered showers and thunderstorms in the late afternoon and evening. Days will remain sunny, but no new widespread heat wave is anticipated.

For the Central Highlands and Southern Vietnam, the weakening southwest monsoon means generally little rain until around 21/7. From 22/7, the southwest monsoon is predicted to strengthen again, leading to an increase in rainfall.

From approximately 23/7 to 26/7, the Central Highlands and Southern Vietnam are likely to experience widespread showers and thunderstorms, with locally heavy rain, primarily concentrated in the late afternoon and evening. Residents should take precautions against whirlwinds, lightning, strong wind gusts, and localized flooding in low-lying areas.
