Onancock, Virginia, given its location on the Eastern Shore of Virginia, is at a moderately high risk for hurricane impacts. This town, relatively close to the coast, is susceptible to coastal flooding due to storm surge and heavy rainfall associated with both tropical storms and hurricanes. Its limited elevation, which is already close to sea level, largely increases the risk of flood impacts. The Chesapeake Bay, which it is located near, can exacerbate the risk of both coastal and inland flooding, especially at high tides. Other hurricane-associated effects such as damaging winds could result in property damage, power outages, and potential loss of life if not properly prepared for. Historically, Onancock has experienced some notable hurricane impacts in the past 30 years. One vivid example is Hurricane Floyd in 1999, which caused significant rainfall, and as such, flooding in the region. Likewise, the back-to-back strikes of Hurricanes Dennis and Isabel in 2003 also proved devastating. These two storms caused widespread flooding and wind damage in Onancock, demonstrating the town's vulnerability to severe storms due to its location and minimal elevation. Climate change projections point towards a potential increase in the intensity of storms in the mid-Atlantic region, meaning the risk of hurricanes impacting Onancock may possibly rise over time.
