Low pressure area intensity may change, complicated heavy rain
Regarding the diễn biến of the low pressure area in the East Sea area, it is forecasted that in the next 1-2 days, this low pressure area is very likely to strengthen into a tropical depression in the central East Sea area (with a probability of about 80%). It is possible that this tropical depression will strengthen into a storm (probability of about 30-40%).
On the night of September 10 and the day of September 11, the area from the south of Nghe An province to Da Nang city and the east of Quang Ngai province, the north of the Central Highlands will have moderate to heavy rain with common rainfall from 30-60mm, locally very heavy rain over 100mm.

The meteorological agency warns that heavy rain in the Central region is likely to continue and develop complicatedly.
From September 14-17, under the impact of the tropical convergence zone with its axis passing through the Central region, the Central provinces are highly likely to continue to have moderate to heavy rain over a wide area, accompanied by a high risk of tornadoes, lightning, flash floods, landslides and localized flooding.
The diễn biến of the low pressure/tropical depression area, especially the trajectory and intensity, may still change. Therefore, the scope and rainfall in the Central region in the coming days are still uncertain and will be continuously updated.
People and local authorities need to regularly monitor the latest forecast and warning bulletins to proactively prevent risks caused by heavy rain, flash floods, landslides and flooding.
