The National Center for Hydro-Meteorological Forecasting has issued a forecast of notable weather trends for the next month (ie from now until September 10).
There are still hot spells but the intensity has decreased
Regarding temperature trends, the average temperature is generally approximately the same as the average of many years in the same period. In the North Central region, the temperature is about 0.5 degrees Celsius lower than the average of many years in the same period. The Northwest region will have a temperature of about 0.5 - 1 degree Celsius higher than the average of many years in the same period.
Hot weather continues to occur in the Northern regions, from Thanh Hoa to Hue and the South Central Coast, but gradually decreases in intensity and frequency.
Previously, from July 11 to August 10, there were 4 hot spells in the Northern region, Thanh Hoa to Hue and the South Central Coast. Notably, during the hot summer in early August, the highest temperature occurred in the Northern region and was concentrated in the midlands and deltas of the North with the peak of the hot weather on August 3 and August 4.
The highest temperature is generally from 38 - 40 degrees Celsius, some places above 40 degrees Celsius such as Lang (Hanoi) is 40.3 degrees Celsius, Phu Ly (Ninh Binh) is 40.2 degrees Celsius.
According to Mr. Nguyen Van Huong - Head of Weather Forecasting Department, National Center for Hydro-Meteorological Forecasting, statistics in the Northern region have occurred at 20 meteorological stations that have recorded the highest temperature value of the day exceeding the previous historical value observed in the same period in August.
"Although the temperature value recorded in this heat wave is not the highest level ever recorded in the summer in the North (usually occurring in June or July), however, compared to the same period in August in previous years, this is still a rare temperature" - Mr. Huong commented.
In the South, hot weather occurred locally in the first days of August with the highest temperature of the day from 35 - 36 degrees Celsius. Some stations recorded the highest temperature value of the day exceeding the historical value of the same period.
Risk of widespread heavy rains
The trend of rainfall nationwide is generally at the same level as the average of many years, especially in the area from Thanh Hoa to Hue and the South Central Coast, the total rainfall is forecast to be 10 - 30% higher than the average of many years in the same period.
The Northern region and the provinces from Thanh Hoa to Hue are likely to experience some widespread heavy rains. In the Central and Southern highlands, in the next month, there will be many days of showers and thunderstorms, mainly in the late afternoon; in which, some days may have moderate to heavy rain.
On a national scale, there is a continued possibility of dangerous weather phenomena such as thunderstorms, tornadoes, lightning, hail and strong gusts of wind.
The phenomenon of heavy rain and thunderstorms, whirlwinds, and lightning can negatively affect production activities and public health. In particular, beware of localized heavy rains that can cause floods, inundation in low-lying areas and landslides in mountainous areas.
Regarding dangerous phenomena at sea, during the forecast period, there is a possibility of 1-2 storms or tropical depressions appearing in the East Sea and possibly affecting the mainland of Vietnam.
According to the average data of many years, in the same period in the East Sea, there will be about 2.4 storms or tropical depressions, 0.93 of which will make landfall in Vietnam.
Storms, tropical depressions and the southwest monsoon are likely to cause strong winds, large waves at sea and affect the activities of ships.
Previously, in the past month, there were 2 storms in the East Sea, including storm No. 3 Wipha and storm No. 4 Comay and 1 tropical depression.
