The National Center for Hydro-Meteorological Forecasting reports that widespread heavy rainfall occurred from October 27-29, with cumulative totals ranging from 200 to 400 mm across Quang Binh to Da Nang, with some areas recording over 700 mm.

Heavy rain also fell in southern Ha Tinh through Thua Thien Hue late last night and early this morning (October 29). Between 7 p.m. last night and 8 a.m. today, rain totals reached over 100 mm in several areas: Hoanh Son (Ha Tinh) recorded 108.2 mm, Quang Kim (Quang Binh) reached 149.6 mm, Cam An (Quang Tri) recorded 201.2 mm, and Quang Dien (Thua Thien Hue) measured 119 mm.

From the night of October 29 through October 30, areas from southern Ha Tinh to Da Nang are expected to receive 70-150 mm of rainfall, with some places likely to exceed 300 mm.

Specifically, tonight and tomorrow, these regions will see moderate to heavy rain, with certain areas forecasted to receive intense rainfall of 50-100 mm, and isolated areas potentially exceeding 200 mm.

By October 30, heavy rain will continue from Quang Binh to Quang Ngai, with totals reaching 30-60 mm, and some areas possibly receiving more than 120 mm. Forecasts warn of intense localized downpours, potentially exceeding 100 mm within a three-hour period.

In addition, sporadic showers and thunderstorms are expected in southern Vietnam today and tonight, with some areas receiving between 15 and 30 mm of rain, and certain spots potentially seeing over 50 mm.

Meteorologists predict the rains will gradually subside across Central Vietnam beginning on October 31. However, heavy rainfall in the region poses a continued risk of flooding in low-lying areas, flash floods along smaller rivers and streams, and landslides on steep slopes.

Flood levels on the Kien Giang River in Quang Binh, specifically in Le Thuy district, reached their peak and are beginning to recede. This morning, water levels remained at 1.32 meters above Alert Level 3. Meanwhile, the Thach Han River in Quang Tri has receded to about 0.3 meters below Alert Level 2.

Kien Giang River levels are expected to gradually decline, reaching 3.1 meters, about 0.4 meters above Alert Level 3, by the morning of October 30. Authorities also expect water levels on the Thach Han River (Quang Tri) and Huong River (Hue) to hover above Alert Level 1. Flooding conditions in Le Thuy, Quang Ninh, and Dong Hoi in Quang Binh are expected to persist for the next 36 to 48 hours.
