What is the greatest danger in a hurricane?

Storm surge

Why are hurricanes the most dangerous?

Hurricanes are categorized by their wind speeds, but the most deadly and destructive threat posed by most hurricanes is the storm surge they can produce. Storm surge is the rapid rise in ocean levels brought about by the powerful winds and low pressure in a hurricane.

How do hurricanes cause flooding?

Though hurricanes are well known for strong and destructive winds, hurricane storm surge is the greatest threat. Storm surge is water that is pushed toward the shore by winds swirling around the storm. This rise in water level can cause severe flooding in coastal areas.

Can hurricanes flood?

Tropical storms and hurricanes have the potential to unload heavy and sustained rainfall that can overwhelm drainage systems and result in flooding. In 2011, Tropical Storm Lee generated up to 15 inches of rain in some areas and caused major flooding along the Gulf and Atlantic.

How far does storm surge go inland?

Storm surge can penetrate well inland from the coastline. During Hurricane Ike, the surge moved inland nearly 30 miles in some locations in southeastern Texas and southwestern Louisiana. All locations along the U.S. East and Gulf coasts are vulnerable to storm surge.

What is the highest storm surge ever recorded?

In the United States, one of the greatest recorded storm surges was generated by Hurricane Katrina on August 29, 2005, which produced a maximum storm surge of more than 28 feet (8.53 m) in southern Mississippi, with a storm surge height of 27.8 feet (8.47 m) in Pass Christian.

How far inland can a 5 foot storm surge go?

Storm surge can reach heights of more than 12 m (40 ft) near the center of a Category 5 hurricane, and fan out across several hundred miles of coastline, gradually diminishing away from the hurricane’s center. Coastal flooding can reach far inland, tens of miles from the shoreline.

What does a 10 foot storm surge mean?

A storm surge is water that is pushed onto shore by a hurricane. It is rarely a “wall of water” as often claimed, but rather a rise of water that can be as rapid as several feet in just a few minutes. The storm surge moves with the forward speed of the hurricane — typically 10-15 mph.

How far inland does storm surge go for Katrina?

6 miles

Was Katrina a Cat 4?

Hurricane Katrina was the largest and 3rd strongest hurricane ever recorded to make landfall in the US. In New Orleans, the levees were designed for Category 3, but Katrina peaked at a Category 5 hurricane, with winds up to 175 mph.

What is dirty side of a hurricane?

The right side of a storm is often referred to as its “dirty side” or “the bad side” — either way, it’s not where you want to be. In general, it’s the storm’s more dangerous side. The “right side” of a storm is in relation to the direction it is moving, according to the National Oceanic and Atmospheric Administration.

Which way does a hurricane spin?

In fact, tropical cyclones — the general name for the storms called typhoons, hurricanes or cyclones in different parts of the world — always spin counterclockwise in the Northern Hemisphere, and spin in the opposite direction in the Southern Hemisphere.

Which structural damage might be expected if a Category 1 hurricane is predicted to hit an area?

A Category 1 hurricane is a dangerous storm that is likely to cause some damage to roofs, gutters and siding. Winds could topple trees and snap tree branches. Winds could also affect power lines and poles, resulting in power outages.
