A tropical cyclone is a low pressure system not associated with a cold front, that develops over tropical and sometimes sub-tropical waters, and has an organized circulation.
A tropical depression is a tropical cyclone in which the maximum sustained surface winds (a one minute average) are 38 miles per hour (33 knots) or less.
A tropical storm is a tropical cyclone in which the maximum sustained surface winds range from 39 to 73 miles per hour (34 to 63 knots). The number of Tropical Storms and Hurricanes increases substantially in August, peaks in mid-September, and decreases towards a minimum by early November.
A hurricane is a tropical cyclone in which the maximum sustained surface winds are 74 miles per hour or greater (64 knots or greater).
A Tropical Storm Watch is issued when Tropical Storm conditions, including winds from 39 to 73 miles per hour, pose a possible threat to a specified coastal area within 36 hours.
A Tropical Storm Warning is issued when Tropical Storm conditions, including winds of from 39 to 73 miles per hour, are expected in a specified coastal area within 24 hours or less.
A Hurricane Watch is issued for a specified coastal area for which a hurricane a or an incipient hurricane condition is a possible threat within 36 hours.
A Hurricane Warning is issued when sustained wind of 74 miles per hour or higher, caused by a hurricane, are expected in a specified coastal area in 24 hours or less.
A Hurricane Warning can remain in effect when dangerously high water or a combination of dangerously high water and exceptionally high waves continues, even though the winds may have subsided below hurricane intensity.
