ORLANDO, Fla. — Tropical Storm Isaias continues to move north along Florida’s coast. The storm was downgraded from a hurricane to a tropical storm Saturday afternoon.
But what’s the difference between a hurricane and a tropical storm?
First off, they are both tropical cyclones or a storm system that has generated over the warm tropical water.
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.
