Stay prepared, wherever you are:
☂️ In Da Nang/Hue/Quang Ngai: keep rain gear ready for tonight 🌊
In South-Central/Southern Vietnam: this is a serious event — avoid low-lying and flood-prone areas, never cross flooded roads or fast water
🏔️ Stay away from riverbanks and steep slopes in affected regions
📱 Follow official updates closely, especially if you’re near the Cam Ly River or in the South
☀️ Up north: stay hydrated if you’re out in that midday heat
Stay safe, everyone — a mixed bag across the country today, but real risk in the south. 🌊
