The lowest category on the Saffir-Simpson scale is the Category 1 with sustained winds of:
74-95 mph
64-82 kt
119-153 km/h
Of course you can get gusts higher than that during the hurricane.
Tropical storms may have gusts reaching that range but if they are not sustained winds, it doesn't get promoted to the category of a hurricane. Note that hurricanes are defined not only by windspeed but also as part of tropical cyclone weather system.
Category 2 hurricanes are sustained winds of:
96-110 mph
83-95 kt
154-177 km/h
Category 3 hurricanes are sustained winds of:
111-129 mph
96-112 kt
178-208 km/h
Category 4 hurricanes are sustained winds of:
130-156 mph
113-136 kt
209-251 km/h
Category 5 hurricanes are sustained winds of:
157 mph or higher
137 kt or higher
252 km/h or higher
Since CAT 5 has no upper limit for wind speed there is no such thing as a CAT 6 or higher.

At what speed does a wind become a hurricane?
Wind is considered hurricane force when it reaches a speed of 74 mph or greater. However, the storm is only considered an actual hurricane if it is a tropical cyclone that sustains such winds consistently for periods of more than one minute.
What factor determines when a tropical storm becomes a hurricane?
When the wind speed is greater than 74 miles per hour, it is considered a hurricane, category one.when the wind exceed 119 km/h the storms is classified as hurricane.
What is the wind speed of a category 1 hurricane?
The wind speed is 74-95 mph in a category one hurricane.
What is the slowest wind ever recorded for a hurricane?
You may be able to find a journal record of no wind on a very rare date on the Antarctic continent.
What is wind speed and what does it have to be with hurricane?
Wind speed is the speed that wind moves at. It relates to hurricanes in that a tropical storm does not become a hurricane until sustained winds reach 74 miles per hour or faster.
What is the official wind speed to create a hurricane?
The minimum wind speed for a storm to be considered a hurricane is 74 mph.
What is the lowest recorded speed of a hurricane spinning?
The minimum wind speed for a hurricane is 74 miles per hour. Below that the storm is not considered to be a hurricane.
At what speed does a wind become a hurricane?
Wind is considered hurricane force when it reaches a speed of 74 mph or greater. However, the storm is only considered an actual hurricane if it is a tropical cyclone that sustains such winds consistently for periods of more than one minute.
What factor determines when a tropical storm becomes a hurricane?
When the wind speed is greater than 74 miles per hour, it is considered a hurricane, category one.when the wind exceed 119 km/h the storms is classified as hurricane.
What wind speed must be reached for a hurricane to develop?
75mphOnce a tropical storm has a wind speed of 74 mph it is officially a hurricane so 74 is the lowest wind speed for a hurricane.
How fast do the wind have to be a hurricane?
The minimum wind speed for a hurricane is 74 mph.
What is the wind speed of a category 1 hurricane?
The wind speed is 74-95 mph in a category one hurricane.
What is the maximum sustained wind speed of a category 2 hurricane?
The maximum wind speed of a category 2 hurricane is 110 mph.
What is the slowest wind ever recorded for a hurricane?
You may be able to find a journal record of no wind on a very rare date on the Antarctic continent.
What is the minium wind speed of a hurricane?
To be considered a hurricane a tropical storm must produces sustained winds of at least 74 mph. The highest reliably recorded sustained winds in a tropical cyclone (hurricane or typhoon) were 195 mph. Gusts have been measured to 253 mph.
What is wind speed and what does it have to be with hurricane?
Wind speed is the speed that wind moves at. It relates to hurricanes in that a tropical storm does not become a hurricane until sustained winds reach 74 miles per hour or faster.
How can you tell the category of a hurricane?
Wind Speed.
