Tropical weather (tropical depressions, tropical storms, and hurricanes) can affect our way of life here in Alabama and Georgia, even though we live far from the coast. Heavy rain and tornadoes are always the biggest threat from a landfalling tropical system, but high winds for a sustained amount of time over a large area are big threats with the strongest storms. Learn more about these tropical troubles below!
Terms to Know:
Tropical Depression: A tropical cyclone with maximum sustained winds up to 38 miles per hour. All tropical cyclones share some common characteristics: a warm-core area of low pressure that lacks fronts; a well defined center of circulation with deep convection (thunderstorms) around it; and it must have its origin and draw its energy from the warm, tropical oceans.
Tropical Storm: A tropical cyclone with maximum sustained winds between 39 and 73 miles per hour. Once a tropical depression becomes a tropical storm, it receives a name from a list that is determined years in advance by the World Meteorological Organization.
Hurricane: A tropical cyclone with maximum sustained winds of 74 miles per hour or greater (sometimes up to 200 mph). The term hurricane is used for Northern Hemisphere tropical cyclones east of the International Dateline to the Greenwich Meridian. The term typhoon is used for Pacific tropical cyclones north of the Equator west of the International Dateline.
