Portsmouth, Virginia's geographical position near the coast of the Atlantic Ocean exposes it to considerable risk from hurricanes, tropical storms, and their associated impacts including wind damage and flooding. The city is almost at sea level with most areas below 12 feet. This low elevation combined with the proximity to the coast increases the town's susceptibility to storm surge and flooding, especially in regions closer to the Elizabeth River and its various branches. Flash floods due to heavy rainfall are also not uncommon during hurricane events. In terms of past hurricane impacts, Hurricane Isabel in 2003 was one of the most significant events, causing widespread destruction due to high winds, rain, and a storm surge. More recently, Hurricane Matthew in 2016 affected Portsmouth, with significant rainfall causing flooding. Beyond these named hurricane events, Portsmouth has also suffered flood damage in numerous unnamed or lesser storms over the past three decades. Therefore, the town's residents should be prepared for the possibility of evacuation, possessing a plan and necessary supplies, keeping an eye on weather reports, and heeding any warnings or notices from local authorities. The potential for severe winds and heavy rainfall affecting infrastructure and homes is also considerable, and property owners may want to consider this in their disaster preparedness and insurance plans.
