Hurricanes in Delaware
When is Hurricane Season in Delaware?
The official hurricane season in Delaware aligns with the Atlantic hurricane season, commencing on June 1 and concluding on November 30. While Delaware is not as frequently impacted by hurricanes as some other U.S. states, it is not immune to these powerful storms. According to the National Hurricane Center, Delaware has been affected by tropical depressions, tropical storms, and major hurricanes.
The following graph visualizes Delaware's hurricane activity.
This image, based on hurricane paths dating back to 1851, showcases the likelihood of Delaware experiencing a tropical cyclone on any given day within the year. Constructed with raw data from the NOAA Hurricane Research Division, the graph compares actual storm landfalls in Delaware to the storm pattern across the entire Atlantic basin. It provides a comprehensive understanding of Delaware's hurricane activity within the context of the Atlantic hurricane season.
Where Do Hurricanes Hit Most in Delaware?
Delaware's Coastal regions are most susceptible to hurricanes, specifically Sussex County and its surrounding areas. These regions are often subjected to hurricane-force winds, with storms frequently causing significant damage to properties and infrastructure.
Inland areas, while less prone to hurricanes, are still susceptible to the impacts of these storms. The flooding caused by hurricanes can often extend well beyond the coastal regions, impacting even the furthest reaches of the state. Storm surges associated with hurricanes can also cause extensive damage to low-lying inland areas that are connected to the sea via waterways.
According to NOAA, storm surge is produced by water being pushed toward the shore by the force of the winds moving cyclonically around the storm.
The graph above provides a visual representation of hurricane risks in Delaware. The risk is defined by the frequency of occurrence weighted by wind speed. The areas in red indicate high-risk zones, typically concentrated along the coastline, particularly in Sussex County. The color's intensity reflects the risk level, graduating from blue to red. Blue zones, representing lower-risk areas, are predominantly located inland.
