Impact & Risks

The combination of moderate wind speeds, frequent tornadoes, and seismic risks poses challenges for construction and safety in Missouri. Tornadoes, which average 45 to 55 annually, can cause significant damage, particularly in areas with less stringent building codes. The Bootheel region faces additional risks from seismic activity, requiring adherence to specific seismic standards. Snow loads, while moderate, can vary significantly across the state, potentially impacting infrastructure and transportation during winter months.
