- The X post from @WeatherMonitors documents rapid flooding in Hoi An, Vietnam's UNESCO-listed ancient town, on November 17, 2025, showing muddy Thu Bon River waters submerging riverside streets amid traditional architecture, with small boats navigating the inundated areas.

- Heavy rainfall from a prolonged tropical depression, totaling up to 850 mm in central Vietnam through November 20, has triggered flash floods and landslides, as reported by Vietnam's National Center for Hydro-Meteorological Forecasting, affecting tourism hubs like Hoi An during peak season.

- Such events are typical in Hoi An's rainy season (September-December), but intensifying storms linked to climate variability have increased flood frequency, with a 2023 World Bank study noting a 20-30% rise in extreme precipitation events in the region over the past decade.
