A storm surge of 4 feet means that water levels have risen by 4 feet above the normal tide level due to a storm. This increase in water level can lead to flooding and inundation of low-lying areas along the coast. Storm surges are often exacerbated by strong winds and low atmospheric pressure associated with storms like hurricanes.
Hurricanes can cause widespread damage, including strong winds that can knock down trees and power lines, heavy rainfall leading to flooding and landslides, and storm surges that can inundate coastal areas. These effects can result in loss of life, property damage, and disruption to infrastructure and services. Recovery efforts can be costly and time-consuming.
Hurricane Agnes reached maximum sustained winds of around 85 mph when it made landfall in Florida in June 1972.
Hurricane severity is measured using the Saffir-Simpson Hurricane Wind Scale, which categorizes hurricanes from Category 1 (weakest) to Category 5 (strongest) based on maximum sustained wind speeds. Other factors like storm surge, rainfall, and potential for damage are also considered in determining a hurricane's overall impact and severity.

Hurricane Floyd caused an estimated $6.9 billion in damage when it struck the United States in 1999. This included damage from strong winds, storm surge, and flooding. The storm affected several states along the East Coast, particularly North Carolina.
