Hurricane Hazards

Tropical storm-force winds are strong enough to be dangerous to those caught outside in them.

Powerful, hurricane-force winds can easily destroy poorly constructed buildings and mobile homes. Debris such as signs, roofing material, and small items left outside become flying missiles in hurricanes. Extensive damage to trees, towers, water and underground utility lines (from uprooted trees), and fallen utility poles cause considerable disruption.

High-rise buildings are also vulnerable to hurricane-force winds, particularly at the higher levels since wind speed tends to increase with height. Research suggests you should stay below the tenth floor, but still above any floors at risk for flooding. It is not uncommon for high-rise buildings to suffer a great deal of damage due to windows being blown out.

Consequently, the areas around these buildings can be very dangerous. The strongest winds usually occur in the right side of the eye wall of the hurricane.

Wind speed usually decreases significantly within 12 hours after landfall. Nonetheless, winds can stay above hurricane strength well inland. Hurricane Charley (2004), for example, battered DeSoto County (75 miles inland) with gusts to nearly 100 mph.

When it comes to hurricanes, wind speeds do not tell the whole story. Hurricanes can produce storm surges, tornadoes, and often, inland flooding. While storm surge is always a potential threat, more people have died from inland flooding in the last 30 years. Intense rainfall is not directly related to the wind speed of tropical cyclones. In fact, some of the greatest rainfall amounts occur from weaker storms that drift slowly or stall over an area. Inland flooding can be a major threat to areas hundreds of miles from the coast when intense rain falls.
