    There are certain storm classifications that distinguish types of storms: Tropical Depression, Tropical Storm and a Hurricane. One major distinction between these different types of storms is the speed of the associated winds.

    A Tropical Depression usually has all of the makings of a storm such as persistent clouds and thunderstorms but the maximum sustained winds are at most thirty eight miles per hour.

    A Tropical Storm also has strong thunderstorms and winds blowing between thirty nine to seventy three miles per hour.

    In the case of a Hurricane, the tropical weather system's winds range from seventy four miles per hour and up."

    基本上Tropical storm 比 depression 還要稍微嚴重一點...

    Tropical Depression

    A tropical cyclone in which the maximum sustained wind speed (using the U.S. 1 minute average standard) is 33 kt (38 mph, 18 m/s). Depressions have a closed circulation.

    Tropical Storm

    A tropical cyclone in which the maximum sustained surface wind speed (using the U.S. 1 minute average standard) ranges from 34 kt (39 mph,19 m/s) to 63 kt (73 mph, 34 m/s). The convection in tropical storms is usually more concentrated near the center with outer rainfall organizing into distinct bands.
