Greenville, Mississippi

12 Land Tracts in Washington County , Deer-Steele Watershed

Greenville, Mississippi, located in Washington County, faces a relatively moderate risk of natural disasters, with a higher risk of river flooding due to its proximity to the Mississippi River. The area's high precipitation levels of 1323.97mm and high humidity of 87% contribute to the risk of flooding during heavy rainfall events. Additionally, the city's location in the Lower Mississippi region exposes it to moderate risks of thunderstorms and tornadoes, which are common in the area.

The city's geological features, including the nearby Yazoo River, Deer-Steele hydrologic unit, and the Lower Mississippi - Yazoo hydrologic subregion, further increase the risk of flooding and water-related disasters in Greenville. The city's flat topography and low elevation make it vulnerable to water inundation during severe weather events. Additionally, while the area is not known for seismic activity, being situated near the New Madrid Fault Zone poses a potential risk of earthquakes that could impact the region's infrastructure and population.

Historical events such as the Great Flood of 1927, which devastated the Mississippi Delta region, serve as a reminder of the area's susceptibility to natural disasters. As climate change continues to exacerbate extreme weather events, Greenville must prioritize disaster preparedness and mitigation efforts to reduce the impact of future disasters. Overall, Greenville's natural hazard risk assessment highlights the importance of understanding and addressing the unique climate and geological factors that contribute to the city's vulnerability to natural disasters.
