Torrential rain triggered flash floods and emergency water rescues across the Southern United States on Memorial Day and the following Tuesday [1].
The extreme weather caused widespread devastation in residential areas and critical infrastructure. These floods disrupted travel and forced residents from their homes, highlighting the vulnerability of the region to tropical remnants.
The flooding was driven by the remnants of Tropical Storm Arthur, which dumped between 15 and 20 inches of rain [1, 2]. This volume of precipitation created multiple flash-flood emergencies throughout the central and southern U.S. [2, 3].
Impacts were particularly severe in western North Carolina and Charleston, South Carolina [1, 3]. In these areas, the sudden surge of water led to the inundation of hundreds of homes [1]. Emergency crews conducted water rescues as streets transformed into rivers, a situation that prompted urgent flash-flood warnings for the Charleston area [3].
While the primary impact was felt in the South, other reports indicated destructive storms affecting the Midwest [4]. However, verified data focuses on the significant rainfall totals and residential damage within the Southern corridor [1, 2].
The event began on May 27, 2024, and continued into the early hours of May 28, 2024 [2]. Local authorities coordinated efforts to evacuate trapped residents and manage the aftermath of the torrential downpours.
“Remnants of Tropical Storm Arthur dumped 15‑20 inches of rain”
The scale of this event demonstrates how the remnants of a tropical system can cause catastrophic inland flooding even after the storm has officially weakened. The inundation of hundreds of homes in North and South Carolina underscores the persistent risk of flash flooding in the U.S. Southeast, where saturated soils and urban drainage systems can be quickly overwhelmed by high-volume rainfall.
