Tropical Cyclone Systems


Tropical Cyclone Systems :

In order of intensity, are called: (1) Tropical Depression (winds between 25 and 38 mph). A tropical depression, the lowest intensity, is given a number once it has a counterclockwise spin and winds of 38 mph or less. (2) Tropical Storm (winds between 39 and 73 mph). When wind speeds reach 39 mph and the storm is given a name from a pre-determined list, a tropical storm is born. While a tropical storm does not produce a high storm surge, its thunderstorms can still pack a dangerous and deadly punch. (3) Hurricane (winds of 74 mph or greater). A hurricane is the most intense tropical event, with five categories and winds ranging from 74 mph to 155 mph or greater: (a) Category One – Winds 74-95 mph; (b) Category Two – Winds 96-110 mph; (c) Category Three – Winds 111-130 mph; (d) Category Four – Winds 131-155 mph; (e) Category Five – Winds greater than 155 mph. (4) Storm Surge is a major concern with hurricanes. The extremely high winds cause ocean water to pile up, creating higher than normal sea levels with waves up to 40 feet in open water. The “eye” is the calm center of a hurricane. Don't be fooled if wind and rain stop during a hurricane. You may just be in the eye of the storm. Listen to the radio to find out when the storm has really passed
