The difference between the two categories is the strength of the wind, or how strong the low pressure is, which drives the wind.

A storm is categorized as a tropical storm if its winds are between 39 and 72 mph. A tropical storm is upgraded to a category 1 hurricane once its winds reach 74 mph.

The maximum winds for a category 1 hurricane is 95 mph. After a storm reaches 95 mph it would be upgraded to a category 2 hurricane.
