The National Center for Hydro-Meteorological Forecasting has just released forecast information on climate trends for the period from August 11 to September 10.
Accordingly, the average temperature during this period in the Northwest, Central and South Central regions is 0.5-1 degree Celsius higher, while the remaining places are about 0.5 degree higher than the average of many years.
Notably, total rainfall (TLM) in most regions across the country is 5-15% higher, especially in the North and Central Central regions from 15-25%; in the Northwest and South Central regions, it is generally at a level approximately equal to the average for the same period.
The meteorological agency also warned that 1-2 storms and tropical depressions are likely to appear in the East Sea and may affect the North and Central regions.
During this period, localized heat waves may appear in the Northern region. Heat waves will continue to occur in the Central region during the first 10 days of the forecast period, with some days experiencing severe heat; after that, the heat waves are likely to gradually decrease from around the end of August.
Meanwhile, the southwest monsoon in the South is likely to continue causing many days of showers and thunderstorms in the Central Highlands and the South, with some days of strong thunderstorms and heavy rain, concentrated in the late afternoon.
At the same time, thunderstorms, lightning, and possibly hail continue to occur nationwide.
During the period from now until September 10, the meteorological agency especially notes that the heat in the Central region can cause fires and explosions in residential and production areas due to increased demand for electricity and a high risk of forest fires.
In addition, the tropical convergence zone continues to operate and is likely to form a tropical depression/storm in the East Sea. The tropical convergence zone will cause the southwest monsoon to be active in the southern seas. It is necessary to be on guard against strong winds and large waves affecting maritime activities and fishing of fishermen.
In the immediate future, tonight (August 11) and tomorrow, in the North and Thanh Hoa, there will be rain, moderate rain and thunderstorms, locally heavy to very heavy rain with rainfall of 20-40mm, in some places over 150mm.
Thunderstorms and localized heavy rain in this area are likely to last until around night of August 12.
Record-breaking daily rainfall
Assessing the continuous thunderstorms in many places over the past month (July 11 - August 10), the Center for Hydro-Meteorological Forecasting said that there have been 4 widespread rains across the country.
Specifically, from July 11-15, July 18-22 and July 28-August 10, mainly concentrated in the North and Central regions, while the Central Highlands and the South from July 11 to August 4 continuously experienced many days of moderate rain, heavy rain, and in some places very heavy rain.
Notably, during the period of rain from July 28 to August 10, due to the influence of a low trough combined with high-altitude wind convergence, the Northern and North Central regions experienced widespread heavy rain, while the Northeast and Northern Delta regions experienced continuous heavy rain from July 30 to August 5.
In which, TLM in the North is 100-300mm, in mountainous areas from 250-500mm, some places are higher like Muong Te 656.5mm... North Central 70-150mm. During the rainy periods, there were some highest daily rainfall values exceeding the historical values of the same period.
According to the meteorological agency, during the period from July 11 to August 10, rainfall across the country was unevenly distributed. Specifically, in the North and North Central regions, rainfall was 15-30% higher, mainly concentrated in the midlands and mountainous areas; other places were generally 20-40% lower than the average for the same period, with some places being over 50%. In particular, the Central Central region had rainfall 50-80% lower than the average for the same period.
In particular, some places in Quang Binh and Thua Thien Hue have TLM higher than the average by 50-80%, some places over 100%. The Central Highlands - Southern region has TLM higher by 40-80%, some places over 150%.
