Risk Overview

About Natural Disaster Risk in Lewis County, Kentucky

Lewis County maintains below-average risk

Lewis County's composite risk score of 41.48 sits slightly below Kentucky's state average of 44.21, earning a very low risk rating. This modest advantage reflects relatively balanced hazard exposure across the county's landscape.

Slightly safer than state average

Lewis County ranks just below the Kentucky state average with a composite score of 41.48 versus 44.21, placing it in the lower-risk half of the state's counties. The county benefits from lower wildfire exposure compared to many Appalachian peers.

Middle ground in regional risk

Lewis County (41.48) falls between higher-risk Letcher County (66.60) and lower-risk Lee County (7.51), making it a moderate-risk area regionally. Unlike Letcher, Lewis faces significantly lower wildfire threat due to different forest composition and land use patterns.

Flooding and tornadoes top the list

Flood risk (64.92) and tornado risk (35.72) are Lewis County's most significant hazards, with flooding substantially exceeding the state average. Earthquake risk (27.00) and hurricane risk (34.13) pose secondary threats, while wildfire risk (15.33) remains relatively low.

Prioritize flood and tornado coverage

Lewis County residents should secure flood insurance given the county's flood risk score of 64.92, well above the state average. Review your homeowners policy's tornado coverage and consider additional protection if you live in areas with history of severe weather impact.

Risk Advisory: Lewis County

Risk Verdict

At the 41th percentile nationally, Lewis County experiences relatively limited natural hazard pressure compared to most of the country. A preparedness foundation — alert registration, household communication plan, and a basic supply review — costs little and remains valuable even at Lewis County's favorable 41th percentile ranking.

Hazard Breakdown

Flood risk is Lewis County's dominant natural hazard, ranked at the 65th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 36th percentile nationally. Additional tracked hazards include hurricane (34th percentile), earthquake (27th percentile), wildfire (15th percentile).

Preparedness Context

Lewis County sits at the 65th percentile nationally for flood exposure. Knowing your property's flood zone designation — available at FEMA's Flood Map Service Center — is the first step toward understanding actual exposure and insurance options. Alongside flooding, tornado exposure at the 36th percentile means households benefit from a multi-hazard preparedness plan rather than focusing on flood alone. Regardless of specific hazard, Lewis County households benefit from a practiced communication plan: a designated out-of-state contact and a pre-agreed evacuation destination established before the season's peak risk period.

Regional Context

The county's composite score diverges by only 2.7 points from the Kentucky average, making Lewis County's hazard profile broadly typical for this part of the state.
