TROPICAL WEATHER

Tropical weather (tropical depressions, tropical storms, and hurricanes) can affect our way of life in Alabama and Georgia, even though we live far from the coast.  Heavy rain and possible tornadoes are always a big threat from a landfalling tropical system, but high winds for a sustained amount of time are always a possibility with the strongest storms.  Here is some more information on these tropical troubles!

Terms to know:

Tropical Depression:  A tropical cyclone over with maximum sustained winds of 38 mph or less.  Tropical cyclones all share several of the same characteristics:  a warm-core low pressure system lacking fronts; a well organized, closed center with deep convection (thunderstorms) around it that draws its energy from the warm ocean waters; and a closed surface wind circulation.

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 that is determined years in advance by the National Hurricane Center.

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.
