According to the National Center for Hydro-Meteorological Forecasting, early this morning (October 23), after entering the coastal waters of Hue City - Da Nang, the tropical depression (weakened from storm No. 12) has weakened into a low pressure area.
Heavy rain in the Central region may last until the end of October
At 7:00 a.m. on October 23, the center of the low pressure area was at about 16.1 degrees north latitude; 108.5 degrees east longitude. The strongest wind in the center of the low pressure area decreased to below level 6.
It is forecasted that in the next 12 hours, the low pressure area will continue to move mainly southwest, weakening and gradually dissipating. Due to the influence of the strengthening cold air combined with the disturbance of the easterly wind and the circulation after the storm, the situation of heavy rain in the Central region and strong winds at sea is still complicated.
From the morning of October 23 to the night of October 24, the area from Ha Tinh to Quang Ngai will have heavy rain and thunderstorms with common rainfall of 100 - 200mm, locally very heavy rain over 300mm. In particular, the area from South Quang Tri to Da Nang will have heavy to very heavy rain with common rainfall of 200 - 350mm, locally over 700mm.
