Additional tracked hazards include earthquake (37th percentile), tornado (19th percentile), wildfire (9th percentile).
Preparedness Context
At the 64th percentile nationally for hurricane exposure, King William 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. Flood at the 51th percentile nationally is King William 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. King William County households near tidal water or low-elevation areas should verify whether they are in a storm surge risk zone.
