Hurricane Categories

Hurricanes are evaluated in a number of ways. Storms are assigned a category based on winds, storm surge and barometric pressure, using the Saffir-Simpson scale.

Category 1
Storms have winds of 74-95 miles per hour, making them the weakest of hurricanes. Even these storms can generate a storm surge of 4 or 5 feet above normal high tide.

Category 2
Storms have winds of up to 110 miles per hour, and can push a storm surge of 6 to 8 feet.

Category 3
Storm winds can reach 130 miles per hour. This is the cutoff for "major" hurricanes, with commensurate storm surge potential of 9 to 12 feet.

Category 4
Winds can be as high as 155 miles per hour, and such a storm brings a 13 to 18 foot storm surge.

Category 5
Storms, with winds greater than 155 miles per hour, are very rare. These monsters can have storm surges of over 20 feet. Only 2 such hurricanes have hit the US this century - Camille in 1969 and Andrew in 1992.
