EVERY COASTLINE IN THE NORTH ATLANTIC IS VULNERABLE to tropical storms, but some areas are more susceptible to hurricane destruction than others.

To understand why as the region heads into what’s forecast to be another busy hurricane season, let’s look more closely at how tropical storms form and what turns them into destructive monsters.

WHY DO HURRICANES FORM?

  1. Warm sea surface water that’s at least about 80 degrees Fahrenheit (26.5 C).
  2. A thick layer of moisture extending from the sea surface to roughly 20,000 feet.
  3. Minimal vertical wind shear, so the thunderstorm can grow vertically without interruption.

These prime conditions are often found in the tropical waters off the west coast of Africa.
