Difficult Run, Virginia, although not a coastal town, could still potentially be severely affected by a hurricane due to its position. It lies southeast of the Appalachian Mountains and northwest of the Chesapeake Bay, and is consequently at a risk of both direct impacts from hurricane-driven rainfall and wind, as well as indirect impacts from increased river flow or surge up the Potomac River. Lowland areas near Difficult Run Stream Valley Park and the Potomac could experience significant flooding, especially if the storm arrives in conjunction with high tides. Furthermore, due to the town’s elevation, there is a decreased but not negligible risk of landslides in higher areas, especially if the ground is already saturated from previous rainfall.
Historically, hurricanes Isabel (2003) and Floyd (1999) brought significant rainfall to this area, causing widespread flooding and wind damage, proving that inland locations in Virginia are not immune to hurricane impacts. Climate change considerations might also mean that future hurricanes could bring heavier rainfall and stronger wind speeds than those observed historically. Preparation and planning should focus on evacuation routes, sheltering options for people living near the river or in high-landslide-risk zones, and disaster response resources, such as those for dealing with wind damage and large-scale power outages.
