A tornado watch has been issued by the Storm Prediction Center for more than 1.5 million people in coastal Georgia and South Carolina until 1 a.m. EDT as Debby continues to trudge across the Southeast. This watch includes areas such as Charleston, South Carolina, and Savannah, Georgia.
Tornadoes are a common occurrence during landfalling tropical storms and hurricanes. They are typically associated with outer rain bands and can form rapidly, often being short-lived. Unlike traditional tornadic storms in the central and southern US, tornadoes in these situations can develop with little to no warning.
