Tysons, Virginia, though situated farther inland, is not immune to the effects of hurricanes and tropical storms, especially considering that the remnants of these weather systems can venture quite a distance from the coast. The flooding risk, mainly from the heavy rainfall that accompanies these systems, is the top concern for Tysons. The city has been impacted by significant rainfall events in the past, and due to its moderate elevation ranging from 250 to 500 feet above sea level, it is subject to flash floods and urban flooding. The city's largely surface-level drainage system, heavy urbanization and high impervious surface area all contribute to the flood risk. History records several notable weather events that have affected Tysons. Hurricane Fran in 1996, and Tropical Storm Lee in 2011 each brought heavy rainfall leading to significant flooding in the area. Hurricane Isabel in 2003 also caused some damage in Tysons, primarily due to high winds that led to power outages, downed trees, and minor structural damage. Therefore, while storm surge and coastal flooding concerns may be lessened by Tysons' inland location, heavy rainfall, flash flooding, high winds, and associated power outages are all risks that need to be seriously considered as part of any hurricane threat assessment for Tysons, Virginia.
