Florissant, Missouri faces a relatively high natural disaster and climate risk due to its location in St. Louis County, Missouri. The area is prone to various hazards such as heavy precipitation, high temperatures, and high humidity levels, increasing the risk of flooding and extreme weather events. Additionally, the presence of fault lines in the region, such as the New Madrid Seismic Zone, poses a potential risk of earthquakes.

The city of Florissant is situated near the Mississippi River, which increases the risk of flooding during periods of heavy rainfall or snowmelt. The proximity to water bodies like the Mississippi River and the Missouri River also heightens the risk of water-related disasters such as flash floods. Furthermore, the city is located in the Lower Missouri hydrologic region, which indicates a susceptibility to water-related hazards.

The presence of the Isthmus Ridges in the area can contribute to higher wind speeds during severe weather events, increasing the risk of wind-related damage.
