Prolonged thunderstorms in the South, possibility of storm number 2 appearing in the East Sea

In the coming days, widespread thunderstorms will continue in the Southern region and the southern East Sea. According to the National Center for Hydro-Meteorological Forecasting, last night and today (July 22), in the Central and South Central regions, there will be scattered showers and thunderstorms, locally heavy rain; in the southern Central Highlands and the South, there will be showers and thunderstorms, locally heavy rain. The rainfall from 0:00 to 15:00 on July 22 was over 60mm in some places, such as: Phu Cat (Binh Dinh) 87.6mm, Dak Mol 5 ( Dak Nong ) 103.6mm... It is forecasted that from the evening of July 22 to July 24, the Central Highlands and the South will have moderate rain, heavy rain and thunderstorms, locally very heavy rain with common rainfall of 50 - 100mm, some places over 180mm, heavy rain concentrated in the afternoon and night.

At sea, from the evening of July 22 to 23, in the sea area from Binh Thuan to Ca Mau and the sea area west of the southern East Sea (including the sea area west of Truong Sa archipelago), there will be strong southwest winds of level 5, sometimes level 6, gusting to level 7 - 8, rough seas; waves from 1.5 - 2.5m high. The central and southern East Sea area (including the sea area of Truong Sa archipelago), the sea area from Binh Thuan to Ca Mau, Ca Mau to Kien Giang and the Gulf of Thailand will have showers and thunderstorms. There is a possibility of tornadoes and strong gusts of wind during thunderstorms.

Explaining the phenomenon of prolonged thunderstorms, MSc. Le Thi Xuan Lan, a hydrometeorological expert, said: The cause is due to the tropical convergence zone (including many thunderstorm cloud nests) lying across the Southern region combined with the strong southwest monsoon. According to satellite cloud images and forecasts from many prestigious centers in the world, this convergence zone, also known as the disturbance zone, is continuing to develop into a low pressure area on the night of July 24 and the morning of July 25 and is likely to strengthen into a tropical depression; the possibility of strengthening into a storm, storm number 2 in the central East Sea area, cannot be ruled out.

This tropical depression (storm) will move up near the Paracel Islands and move east-northeast toward the Philippines. The reason is that offshore, east of the Philippines, there is a large storm Doksuri that could reach level 15 or level 16 (super typhoon) in the coming days. With a distance of less than 2,000 km, the above storm will attract the tropical depression toward itself. This is an interaction that people often call a double storm.

Ms. Lan said: "The big storm Doksuri is moving east-northeast in the East Sea, which is the reason why it did not move into the central region of our country as I reported more than 10 days ago. I want to clarify the cause and risk of storm No. 2 appearing in the coming days because there are many marine economic activities in this sea area such as fishing, oil and gas exploitation and sea tourism. In particular, it is currently summer, many sea tourism activities and island tours are very developed, so there needs to be clear warnings so that everyone can prepare for prevention. On the mainland, the entire South will have widespread thunderstorms that will last until the end of the month."

According to Ms. Lan, in the coming days, we need to continue to monitor and update the specific developments regularly. However, people, especially those who have activities at sea, need to pay special attention to dangerous weather in the southern East Sea area stretching from Nha Trang to Kien Giang.
