Severe weather has begun to impact southern Vietnam, bringing with it intense rainfall, thunderstorms, and rising tides, which could lead to serious flooding and saltwater intrusion, particularly affecting the Mekong Delta and surrounding areas.
According to Le Dinh Quyet, the head of the Southern Regional Hydro-Meteorological Center, the weather troubles began on February 12, 2024. The influence of the tropical low-pressure system has spurred uncharacteristic storms across the region. "The tropical low-pressure system has caused unusual weather conditions for the southern region leading to the forecast of rain and storms," remarked Quyet.
April and May typically herald the end of the dry season, yet reports indicate significant rain has already started to fall across southern Vietnam with exceptional intensity. On February 12, abnormalities were noted, with thunderstorms and scattered rain expected to cover approximately one-third of the area during the evening.
Forecasts predict this messy scheme to persist, with rain continuing to develop over the next few days. Quyet highlighted this rain will not only be persistent but could increase: "Tidal peaks during this period are expected to reach alarming levels, which could lead to localized flooding. By February 15, the rainfall is expected to taper off," he added.
The Southern Regional Hydro-Meteorological Center announced specific data indicating the expected tidal heights from February 13 to February 15, matching alarming levels. Areas such as Phu An and Nha Be could reach levels approximated to 1.47 to 1.52 meters near alarm level II, with significant rising tides observed early and late daily.
Meanwhile, monitoring stations such as Bien Hoa are also expecting levels near 1.70 to 1.80 meters, teetering near alarm level I. Tidal conditions also remain elevated, and observers are advised to remain vigilant as they could influence conditions across much of southern Vietnam's river deltas.
This situation isn't just about rain and rising tides; saltwater intrusion is also becoming worrisome across the Mekong delta. The National Center for Hydro-Meteorological Forecasting reported increased salinity levels particularly affecting the Mekong Delta due to diminished freshwater inflows resulting from seasonal tidal changes and upstream influences from the Mekong River.
Reports suggest salinity levels will peak around February 16 but continue strong beyond, creating pressure for agriculture and local freshwater sources. Like the floods anticipated, saltwater intrusion can severely impact local farming practices and crop output for many communities reliant on the river systems.
While immediate impacts seem dire with rain and tidal fluctuations causing probable flooding, experts remain hopeful for recovery after February 15, where rainfall expectations are predicted to stabilise. Meanwhile, residents are urged to remain attentive during this challenging time.
Local authorities are taking measures to mitigate sporadic flooding and improve public safety during this stretch of unpredictable weather. They are actively monitoring the rising tides and rain forecasts to provide timely information to communities at risk.
Overall, southern Vietnam faces significant weather challenges, particularly concerning flooding and saltwater intrusion, impacting both local ecology and agriculture. Residents are encouraged to stay informed and prepared as the situation evolves.
