The Outer Banks are at a significant risk of being impacted by tropical cyclones (hurricanes and tropical storms) during September. Historically, this period is among the most active times for hurricane activity in the Atlantic Basin, with many storms making landfall along the North Carolina coast during the month.
According to records from the National Hurricane Center (NHC), the Outer Banks have been affected by several tropical cyclones in September over the years. For instance, in 2017, Hurricane Irma made landfall in Florida but brought damaging winds and storm surge to the Outer Banks. Similarly, in 2018, Hurricane Florence caused catastrophic flooding and damage in the region.
Some of the key factors that contribute to the formation and intensification of tropical cyclones during this time include:
*
-
* High ocean temperatures (above 26.5°C/80°F) in the Atlantic Ocean, particularly in the tropical and subtropical regions.
* Moisture-laden air from the Gulf Stream and the Intertropical Convergence Zone (ITCZ).
* Low atmospheric pressure, often associated with a strong subtropical high-pressure ridge.
* Wind shear, which can weaken storms or contribute to their intensification.
* The interaction between the subtropical high-pressure ridge and the tropical cyclone’s circulation pattern.
* The storm’s track and speed, which can influence the severity of the impact on the Outer Banks.
When a tropical cyclone approaches the Outer Banks, residents and visitors can expect strong winds, heavy rainfall, and potentially disastrous storm surge flooding.
