Severe flash flooding caused by Tropical Storm Maysak swept through southwest China on May 19, 2024, resulting in widespread devastation [3].

The scale of the inundation underscores the vulnerability of the region to extreme weather events, forcing tens of thousands from their homes and disrupting critical infrastructure.

Heavy rain associated with the storm triggered rapid flooding in Duyun City, located in the Guizhou province [1, 2]. In some areas, the force of the water was strong enough to sweep vehicles into large pileups, creating catastrophic scenes of property damage [2].

Local authorities said more than 80,000 people were forced to flee their homes as water levels rose [3]. The evacuations were necessary to prevent further casualties as the storm system moved across the region.

In the Guangxi region, the impact was equally severe. State media said at least two people died in Guangxi due to the flooding [1]. Rescue efforts continued as officials worked to manage the aftermath of the storm's landfall.

The disaster affected both urban and rural areas, with Duyun City serving as a primary focal point for the flash flood damage [2]. Emergency responders focused on extracting residents from submerged areas and stabilizing damaged roads.

While the death toll in Guangxi is confirmed at two, the full extent of the property loss in Guizhou and surrounding areas remains under assessment [1, 2].

The rapid displacement of 80,000 people highlights the intensifying risk of flash flooding in southwest China. When tropical storms interact with the region's specific topography, the resulting water surges can overwhelm urban drainage and rural defenses, necessitating large-scale emergency evacuations to prevent higher casualty rates.
