Natural Hazards: Hurricanes

Warm ocean water (more than 80°F), winds coming together to force air upward, winds flowing outward above the storm, humid air rising, light winds outside the hurricane

Cold ocean water, strong winds from the north, dry air, high pressure, no clouds

Warm ocean water (less than 80°F), winds moving downward, dry air sinking, strong winds inside the hurricane, high humidity

Calm winds, low humidity, cold air rising, no evaporation, weak ocean currents

Spiral winds around a calm center called an eye

The eye can be up to 30 miles wide

A hurricane can have torrential rains, high winds, and a storm surge

Hurricanes always last less than a day
