The wind causes the water to pile up higher than the ordinary sea level. Low pressure at the center of a weather system also has a small secondary effect, as can the bathymetry of the body of water. It is this combined effect of low pressure and persistent wind over a shallow water body which is the most common cause of storm surge flooding ...
The relatively quick surge in sea level can move miles/kilometers inland, flooding homes and cutting off escape routes. The NOAA report about sea level states that the likeliness of storm surges during a hurricane has increased due to climate change, and by 2050, the chance of moderate flooding occurring will have increased by 10 times.
The Hurricane Surge Index is a metric of the potential damage a storm may inflict via storm surge. It is calculated by squaring the dividend of the storm's wind speed and a climatological value (33 m/s or 74 mph), and then multiplying that quantity by the dividend of the radius of hurricane-force winds and its climatological value (96.6 km or ...
“I’m telling you it doesn’t take an onshore or a direct hit from a hurricane to pile up the water,” he said. “We could see a significant amount of storm surge on the west coast of ...
Storm surge is massive amounts of water that come ashore during a hurricane and up into rivers and bays. It often causes the most damage and the most deaths. It often causes the most damage and ...
Storm surge is the greatest threat to life and property from a hurricane, at least along the coast. Inland the greatest threat is flooding.
The surge first affected Granma and Santiago de Cuba provinces while Ivan was south of Jamaica. The offshore island of Cayo Largo del Sur recorded 16 ft (5 m) during the storm. [14] During Ivan, rainfall reached 13.33 inches (339 mm) in Isabel Rubio, and several areas recorded over 4 inches (100 mm). [14]
A storm surge is a combination of high tides and strong winds pushing water inland, posing a significant flooding risk to coastal communities, according to the National Hurricane Center.
