90 miles per hour
A tropical storm becomes a hurricane when its sustained winds reach or exceed 74 mph (119 km/h). This increase in wind speed marks the transition from a tropical storm to a hurricane on the Saffir-Simpson Hurricane Wind Scale.
Wind speed is the speed at which air moves from one place to another. Wind speed is a critical factor in determining the intensity of a hurricane, as higher wind speeds are associated with more powerful and destructive storms. Hurricane categories are based on the maximum sustained wind speed of the storm.
A tropical storm becomes a hurricane when its winds reach 74 mph.
The eye of a hurricane is typically calm and windless, with little to no rotation. Therefore, the speed of the eye of a hurricane is near zero, as it is the center of the storm where the strongest winds are found in the eyewall surrounding it.
The minimum wind speed for a storm to be called a hurricane is 74 mph.
The minimum wind speed for a storm to be considered a hurricane is 74 mph.

Hurricane Andrew obviously started as a Tropical storm . every single hurricane starts as a tropical storm hurricanes can sometimes go from a tropical storm to A Up from hurricane to a tropical storm very quickly . but the wind speed to start a hurricane is 74 anything less is a tropical storm
74 mph or more
74 mph or more
The minimum wind speed for a hurricane is 74 miles per hour. Below that the storm is not considered to be a hurricane.
It refers to the wind speed of the storm.
The category of the storm - depends on the wind speed, and barometric pressure reading.
By measuring the sustained wind speed. If the wind speed of a tropical cyclone is anywhere in the range of 39 to 73 mph then it is a tropical storm. If the wind speed is 74 mph or greater then it is a hurricane.
Interestingly, the storm Known as Allison never became a hurricane, but peaked as tropical storm with 60 mph winds. A storm must have winds of at least 74 mph to be a hurricane. Despite not being a very strong storm, Allison produce heavy flooding from from rain. It is the only Atlantic storm to have its name retire that did not become a hurricane.
Just outside the "eye" of the storm in what is called the eyewall.
