The aftermath of the heavy rains and floods caused by Typhoon No. 6 has not yet been resolved, and Central Vietnam continues to face various adverse weather conditions, including the activity of a low-pressure area over the sea and strong air currents combined with disturbances in the easterly winds, leading to prolonged heavy rainfall, which increases the risk of landslides and widespread flash floods.
According to Mr. Mai Van Khiem, Director of the National Center for Hydro-Meteorological Forecasting, in the first ten days of November 2024, many dangerous weather patterns are expected to impact our country, especially the Central provinces.
From approximately November 3-10, Central Vietnam may be affected by a combination of several adverse weather patterns that will bring heavy rainfall, including a low-pressure area in the South and Central East Sea, along with the continuous reinforcement of cold air interacting with strong easterly winds. This weather pattern is expected to cause exceptionally heavy rains, particularly in the Central provinces.
Mr. Khiem indicated that this will be a widespread instance of exceptionally heavy rain, with a very high risk of heavy rainfall events that could lead to major flooding at alert level 3 in the Northern and Central coastal provinces, extensive flooding, flash floods, and landslides in mountainous areas.
Central Vietnam is about to face exceptionally heavy rains, posing a particularly high risk of flash floods, landslides, and extensive flooding.
This rainfall event is assessed to be potentially more dangerous than the rain caused by Typhoon No. 6 because the area of heavy rain is not only concentrated in the provinces that have already experienced significant rainfall recently (from Ha Tinh to Da Nang) but is also expanding southward, specifically to the provinces from Quang Nam to Phu Yen.
The National Center for Hydro-Meteorological Forecasting has noted that after November 10, heavy rains in Central Vietnam will have a complex development with the possibility of 2-3 more heavy rainfall events, with the first half of November seeing significant rain in the provinces from Ha Tinh to Quang Ngai, and the latter half of November and early December focusing on the provinces from Quang Binh to Phu Yen.
According to Mr. Mai Van Khiem, during the period from October 26-30, Central Vietnam experienced very heavy rainfall due to the influence of Typhoon Tra Mi, which has caused reservoirs to accumulate more water, and the soil has become saturated, making the upcoming exceptionally heavy rains from November 3 pose a very high risk of major flooding.
Additionally, there is a particularly high risk of flash floods and severe landslides in the Central provinces, alongside the likelihood of widespread flooding.
Moreover, in the context of complex rainfall and flooding, ensuring the safety of hydropower and irrigation reservoirs is also a significant concern for local authorities and residents.
This agency recommends that the Civil Defense/Disaster Prevention and Search and Rescue Committees of various Ministries, sectors, and localities pay attention to directing relevant agencies to regularly update information on forecasts and disaster warnings issued in accordance with regulations. They should guide disaster prevention forces to review vulnerable points for flash floods and landslides, as well as blockages in river and stream flow to take timely preventive and responsive measures.
Furthermore, they should review and provide information about sensitive areas and activities that are susceptible to natural disasters to effectively organize forecasting, warning, and communication regarding disasters.
They should also ensure that reservoir owners strictly and fully comply with regulations regarding the provision of monitoring data, operational information, and forecasts to meteorological and hydrological units to serve forecasting and warning tasks as required.
