A category 1 hurricane has sustained winds of 74-95 mph. Category 2, 96-110 mph.
Hurricane Katrina started out as a tropical depression, as most hurricanes do, then strengthened to a tropical storm and then a category 1 hurricane. Nor hurricane ever actually starts at hurricane intensity, and they have to go through category 1 to get to the other categories.
A category 1 hurricane has sustained winds of 74 to 95 mph and is expected to cause mostly minor damage. A category 5 hurricane has winds of at least 156 mph and is expected to cause catastrophic damage.
The difference in maximum sustained wind speeds between a category 1 and category 2 hurricane is 15-25 mph. Category 1 hurricanes have maximum sustained winds of 74-95 mph, while category 2 hurricanes have maximum sustained winds of 96-110 mph.
Technically there are only five categories of hurricane strength. The other levels are for systems of less than hurricane strength. These categories are determined by sustained wind speed. Below hurricane strength Tropical Depression: 38 mph or less. Tropical Storm: 39-73 mph Hurricanes Category 1: 74-95 mph Category 2: 96-110 mph Category 3: 111-129 mph Category 4: 130-156 mph Category 5: 157 mph or greater.
A category 1 hurricane in the weakest hurricane, with winds up to 95 mph. The strongest is a category 5 hurricane.
Hurricane Irene hit Cat 1 - Cat 3
Hurricane categories range from category 1 to category 5.
Hurricane ratings are bases on maximum sustained wind speed. A category 1 hurricane has sustained winds of 74-95 mph. A category 5 hurricane has winds over 156 mph.
There are 5 categories from category 1 to category 5.There are 5 categories for hurricanes, 1-5 based on winds speeds and an additional 2 categories (tropical depression and tropical storm) for tropical cyclones below hurricane strength.
Hurricane Katrina started out as a tropical depression, as most hurricanes do, then strengthened to a tropical storm and then a category 1 hurricane. Nor hurricane ever actually starts at hurricane intensity, and they have to go through category 1 to get to the other categories.
There are 5 categories of hurricane, with a category 1 being the weakest and a category 5 being the strongest.

The difference in maximum sustained wind speeds between a category 1 and category 2 hurricane is 15-25 mph. Category 1 hurricanes have maximum sustained winds of 74-95 mph, while category 2 hurricanes have maximum sustained winds of 96-110 mph.
I think you want to know about the Saffir Simpson Scale, there are actually there are 7 wind categories, they're listed below:A Tropical Depression is anything less than 39- MPH.A Tropical Storm wind speed is 39-75 MPH.A Category 1 Hurricane is 75-95 MPH.A Category 2 Hurricane is 96-110 MPH.A Category 3 Hurricane is 111-130 MPH.A Category 4 Hurricane is 131-155 MPH.A Category 5 Hurricane is 156+ MPH.
The difference is 1 .
The difference between -1 and 3 is 4.
