Risk Overview

About Natural Disaster Risk in Smith County, Mississippi

Smith County's composite risk slightly below average

With a composite risk score of 47.20, Smith County ranks as Relatively Low—better than the national average. This positioning reflects a mixed hazard profile where some risks exceed national norms while others remain manageable.

Below-average risk in Mississippi's landscape

Smith County's score of 47.20 sits comfortably below Mississippi's state average of 50.94, placing it in the lower half of risk exposure statewide. This favorable standing provides some protection relative to neighboring counties facing higher composite threats.

Smith County faces mixed risk compared to neighbors

Smith County's 47.20 score places it between safer Tishomingo County (37.09) to the north and riskier Sunflower County (69.62) to the west. The county's hurricane risk (83.90) notably exceeds that of inland neighbors, reflecting its proximity to Gulf coast threats.

Hurricanes and tornadoes pose greatest threats

Smith County residents face outsized hurricane risk (83.90) and significant tornado exposure (71.15), both driven by seasonal weather patterns. Flood risk remains moderate (40.81), making these wind-driven hazards the primary concern for preparedness planning.

Prioritize wind and flood coverage now

Homeowners should ensure comprehensive wind and hurricane coverage as a baseline, given the 83.90 hurricane risk score. Adding flood insurance is prudent given moderate flood exposure, especially in low-lying areas near streams and tributaries.

Risk Verdict

Natural hazard pressure in Smith County is below the national midpoint, with a composite score at the 47th percentile. At the 47th percentile nationally, Smith County's natural hazard profile is comparatively favorable — community resilience is reinforced when individual households maintain a reviewed emergency plan.

Hazard Breakdown

Hurricane risk is Smith County's dominant natural hazard, ranked at the 84th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 71th percentile nationally. Additional tracked hazards include earthquake (49th percentile), wildfire (47th percentile), flood (41th percentile).

Preparedness Context

Hurricane exposure at the 84th percentile nationally makes Smith County a county where pre-season preparedness — not storm-day preparation — determines outcomes. Smith County evacuation decisions under a watch or warning benefit from prior planning, not routes improvised under time pressure. Smith County's tornado exposure at the 71th percentile nationally adds a hazard layer that can persist or intensify after hurricane-force winds have passed, particularly in low-lying inland areas. Smith County residents benefit from registering with the county's special-needs evacuation registry if household members have mobility limitations, require electricity-dependent medical equipment, or cannot self-evacuate — registration in advance of storm season is required.

Regional Context

Smith County's risk score is broadly comparable to the Mississippi county average, with a 3.7-point gap that places the county near the center of the state's hazard distribution.
