What caused the flood in Galveston?

The flood in Galveston was primarily caused by Hurricane Harvey in August 2017, which brought unprecedented rainfall to the region. The storm stalled over Texas, leading to excessive and prolonged rainfall that overwhelmed drainage systems and caused widespread flooding. Additionally, the geography of Galveston, with its low-lying areas, contributed to the severity of the flooding. The combination of heavy rain and storm surge led to significant damage and loss of life in the city.
