Category Sustained Wind Speed Storm Classification Tropical Depression Less than 39 mph (63 km/h) Organized showers and thunderstorms with low pressure Tropical Storm 39 to 73 mph (63 to 118 km/h) Named storm with defined circulation Category 1 Hurricane 74 to 95 mph (119 to 153 km/h) Very dangerous winds will produce some damage Category 2 Hurricane 96 to 110 mph (154 to 177 km/h) Extremely dangerous winds will cause extensive damage Category 3+ Hurricane 111 mph or higher (179 km/h or higher) Devastating damage will occur Measurement and Dynamics The wind speed of a tropical storm is measured using a method that averages the velocity over a one-minute period at a height of 10 meters (about 33 feet) above the ground or water surface.
Tropical Storm Wind Speed Categories and What They Mean
These systems derive their energy from warm ocean waters, and as they organize, they begin to exhibit the characteristic rotating winds that signal a mature tropical cyclone. Furthermore, the most widespread threat posed by these systems is often not the wind, but the torrential rainfall and subsequent flooding.
Understanding the wind speed of a tropical storm is essential for grasping the power and potential impact of these meteorological events. This stage is reached after a tropical depression and before the system escalates to a hurricane or typhoon.
Tropical Storm Wind Speed Categories and What They Mean
Defining the Tropical Storm Wind Speed Range The term "tropical storm" refers to a specific intensity level within the spectrum of tropical cyclones. The defining characteristic of this phase is the range of its sustained wind speeds, which meteorologists use to categorize the system's severity.
These velocities are sufficient to snap tree limbs, overturn unsecured objects, and cause significant damage to roofs, siding, and fencing.
