What are the types of storm surge?
There are two major types of storms, tropical and extratropical storms. In principle there are more, such as polar lows, cold surges, and medicanes (Mediterranean hurricanes), which regionally play a role with storm surges, but this chapter is limited to the two main types.
What is the storm surge for Category 5?
Category 5 hurricanes can produce a storm surge 20 to 25 feet high that can push miles inland, often destroying everything along the coast and flooding low-lying areas well ashore.
What is the storm surge of a category 4 hurricane?
Category 4—Winds 130-156 mph, storm surge 13–18 feet, extreme damage with destroyed roofs and mobile homes, downed trees, cut off roads, and flooded homes.
What is a Category 4?
Category 4 is the second-highest hurricane classification category on the Saffir–Simpson Hurricane Scale, and storms that are of this intensity maintain maximum sustained winds of 113–136 knots (130–156 mph, 209–251 km/h).
What is a Category 2?
Category 2 hurricane: Extremely dangerous winds will cause extensive damage. Winds range between 96 and 110 mph during a Category 2 hurricane. There is a bigger risk of injury or death to people, livestock and pets from flying debris.
What causes a storm surge?
The two main meteorological factors contributing to a storm surge are a long fetch of winds spiraling inward toward the storm, and a low-pressure-induced dome of water drawn up under and trailing the storm’s center.
What is a potential storm surge?
A storm surge is a potentially devastating rise in the sea surface caused by extratropical cyclones or by tropical cy- clones such as hurricanes and typhoons. Surges can lead to large loss of human life, destruction of homes and civil in- frastructure, and disruption of trade, fisheries, and industry.
What does storm surge mean?
Storm surge is the abnormal rise in seawater level during a storm, measured as the height of the water above the normal predicted astronomical tide. The surge is caused primarily by a storm’s winds pushing water onshore.
When does storm surge happen?
A storm surge is an abnormal rise of seawater that occurs when water is pushed inland as a result of high winds from a storm, usually tropical cyclones (hurricanes, typhoons, and cyclones).
