Risk Overview

About Natural Disaster Risk in Union County, Florida

Union County is exceptionally safe

Union County's composite risk score of 10.88 places it in the "Very Low" category, making it one of America's safest counties for natural disaster risk. This remarkably low exposure reflects Union's inland, sparsely populated character and distance from major storm-prone zones.

Florida's lowest-risk county by far

Union's 10.88 score is a stark outlier compared to Florida's 75.74 state average, making it by far the state's safest county. Its flood risk of 11.07 is extraordinarily low, reflecting the county's inland topography and minimal precipitation hazard.

Dramatically safer than all peers

Union's 10.88 risk score is incomparably lower than any neighboring county, including Taylor (65.43), Suwannee (71.34), and Sumter (87.60). The county stands alone as a natural disaster safety outlier in northern Florida.

Wildfire and hurricane risks remain minimal

Even Union's highest risk category—wildfire at 73.86—remains well below most Florida counties' overall risk scores. Hurricane risk of 81.48 and tornado risk of 27.70 round out a hazard profile that is exceptionally benign by state and national standards.

Standard homeowners insurance suffices

Union County residents can rely on basic homeowners insurance without the enhanced coverage demands facing higher-risk Florida counties. A standard emergency kit and evacuation plan provide adequate preparedness for this exceptionally low-risk area.

Risk Advisory: Union County

Risk Verdict

Union County sits in the lower tier of U.S. counties for natural disaster exposure, ranked at the 11th percentile nationally. A 11th percentile score positions Union County among the nation's lower-risk counties, a genuinely favorable outcome — one that simple, low-cost preparedness habits can reinforce further.

Hazard Breakdown

Hurricane risk is Union County's dominant natural hazard, ranked at the 81th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 74th percentile nationally. Additional tracked hazards include tornado (28th percentile), earthquake (27th percentile), flood (11th percentile).

Preparedness Context

At the 81th percentile nationally for hurricane exposure, Union County households benefit from reviewing both homeowners and flood insurance coverage before storm season begins — standard policies often exclude storm surge, which is the leading cause of hurricane fatalities. Wildfire at the 74th percentile nationally is Union County's secondary hazard, often intensified by the same weather systems that produce hurricane conditions. Hurricane-force winds cause direct property damage, but storm surge causes the majority of hurricane-related deaths. Union County households near tidal water or low-elevation areas should verify whether they are in a storm surge risk zone.

Regional Context

Union County falls 64.9 points below Florida's typical county risk level, making it one of the safer natural-hazard environments in the state.
