The forecast for the evening and night of June 7th indicates showers and scattered thunderstorms in the mountainous and midland areas of Northern Vietnam, with some areas experiencing heavy rain, with rainfall amounts of 15-30 mm, and some areas exceeding 70 mm.

On the afternoon and evening of June 7th, showers and thunderstorms are expected in the South Central region, Central Highlands, and Southern Vietnam, with localized heavy rainfall of 20-40 mm, and in some areas exceeding 80 mm. During thunderstorms, there is a possibility of tornadoes, lightning, hail, and strong gusts of wind.

Localized heavy rainfall is likely to cause flash floods on small rivers and streams, landslides on slopes, and flooding in low-lying areas.

Warning of natural disaster risk level due to tornadoes, lightning, and hail: Level 1.

The center reported that currently (June 7th), the central and southern areas of the South China Sea (including the waters around the Spratly Islands), and the sea area from Binh Thuan to Ca Mau are experiencing scattered showers and thunderstorms.

The forecast for day and night of June 7th indicates scattered showers and thunderstorms in the central and southern South China Sea (including the waters around the Spratly Islands), the sea area from Binh Thuan to Ca Mau, Ca Mau to Kien Giang, and the Gulf of Thailand. During thunderstorms, there is a possibility of tornadoes, strong gusts of wind (level 6-7), and waves exceeding 2 meters. All vessels operating in these areas are at risk of being affected by tornadoes and strong gusts of wind.

According to the Center, on June 6th, the area from Thanh Hoa to Phu Yen experienced hot weather, with some places experiencing intense heat. The highest daily temperatures were generally 35-37 degrees Celsius, with some places exceeding 37 degrees Celsius, such as Tuong Duong ( Nghe An ) at 37.3 degrees Celsius and Dong Ha (Quang Tri) at 37.9 degrees Celsius. The Northern region experienced localized heatwaves. The lowest relative humidity was generally 60-65%.

Forecast for June 7-8: The area from Thanh Hoa to Phu Yen will experience hot weather, with some areas experiencing intense heat. Maximum temperatures will generally range from 35-37°C, with some places exceeding 38°C. Minimum relative humidity will generally be 50-55%. The northern delta and midland areas will also experience hot weather with maximum temperatures generally ranging from 35-36°C, with some places exceeding 36°C. Minimum relative humidity will generally be 55-60%.

The center stated that from June 9th, the heatwave in the northern delta and midland areas is likely to end; from June 10th, the heatwave in the area from Thanh Hoa to Phu Yen will gradually subside.

Warning of natural disaster risk level due to heatwave: Level 1.

According to the Center, due to the effects of hot and intensely hot weather combined with low humidity, there is a high risk of explosions and fires in residential areas due to increased electricity demand, and a risk of forest fires.

In addition, hot weather can cause dehydration, exhaustion, and heatstroke in the human body when exposed to high temperatures for extended periods.

The center notes that the temperature forecast in heatwave reports and the actual perceived temperature outdoors can differ by 2-4 degrees Celsius, or even more, depending on surface conditions such as concrete or asphalt.
