While Hanover, Virginia is not a coastal town, its location still allows it to be impacted by hurricanes, typically being in the path of storms that have weakened after making initial landfall. Increased rainfall due to these systems can cause the Pamunkey and South Anna rivers, among other local water bodies, to overflow, leading to flooding. This is particularly true during a slow-moving storm or a storm that stalls over the region. In terms of elevation, Hanover lies in the Piedmont region of Virginia, just east of the mountainous regions of the state -- it is relatively low-lying with an average elevation around 200 feet. This further increases flood likelihood during substantial rainfall events. Historically, multiple tropical systems have led to significant impacts in Hanover. Hurricane Isabel in 2003, for example, caused extensive damage due to high winds and heavy rainfall, leading to widespread power outages, downed trees and flooding. Meanwhile, remnants of Tropical Storm Gaston in 2004 caused catastrophic flooding in the Richmond metropolitan area, which Hanover is part of. Similarly, Hurricane Irene in 2011 passed through with its strong winds causing damage and power losses. As climate change intensifies storm systems, increased precautionary and preventative measures should be taken to mitigate the negative impacts of such events in the future.
