Guide to the Deadliest Storms

Hurricanes are violent storms that devastate coastal areas, putting lives, homes and businesses at risk.

Hurricanes are born from storms that increase their power by the warm and humid air that they find on their way when crossing subtropical waters. The hot air rises into the storm.

The air forms eddies to fill the storm’s low pressure, sucking air in and up, reinforcing the low pressure.

The storm rotates due to the rotation of the Earth and the energy of the hot ocean water increases the speed of the winds, as the storm strengthens.

When the wind speed reaches 119km / h the storm officially becomes a hurricane (in the Atlantic and the Eastern Pacific) or a typhoon (in the Western Pacific).

“Everybody has a plan until they hit him in the face. Well, we’re about to get hit in the face.” Bob Buckhorn, Mayor of Florida, before Hurricane Irma (2017)

The eye of the hurricane, which has a calmer climate, is surrounded by a wall of rain storms. At the bottom of that wall of the eye are the fastest winds, but violent currents of air sweep upward.

Under the eye of the hurricane there is a collection of water that can be released when it hits land. These waves of water can cause more flood damage than the force of winds.

Hurricane size is measured primarily with the Saffir-Simpson scale. In the Asian Pacific and Australia they use other scales.

Winds of 119-153km / h. Small floods, certain damage to structures. Sea level rise + 1.2m-1.5m

Winds of 154-177km / h. Potential damage to roofs and trees. Sea level rise + 1.8m-2.4m

Winds of 178-208km / h. Severe flooding and damage to buildings. Sea level rise + 2.7m-3.7m

Hurricane Sandy (2012) caused damage valued at $ 71 billion in the Caribbean and in New York.

Winds of 209-251km / h. Shattered roofs and serious structural damage to buildings. Sea level rise + 4m-5.5m

Hurricane Ike (2008) hit the Caribbean and Louisiana.

Winds of 252km / h or more. Serious damage to buildings and severe flooding further offshore. Sea level rise + 5.5m

Hurricane Irma (2017) caused devastation in the Caribbean islands.

“I have news for everyone who is thinking that they can easily cope with this storm: that will be one of the biggest mistakes they can make in life.” New Orleans Mayor Ray Nagin before Hurricane Gustav hit in 2008.
