Storm surges, or abnormal rises in seawater, are among the most dangerous hazardous events a hurricane or severe tropical storm can cause. They can bring extensive floods, cause property damage, and result in loss of life. Different types of storm surges vary in severity from minor to extreme and can occur due to wind speed, direction, or size of a storm. Apart from coastal areas, they can also affect infrastructure and commerce. To protect yourself and your property, evacuate when advised, secure your home or business, and keep abreast of weather forecasts and emergency instructions.

The Hidden Dangers of Storm Surges: Understanding the Risks
Storm surges, also referred to as storm tide or tidal surge, are the abnormal rise in seawater that occurs during a severe storm or a hurricane. Storm surges are one of the most dangerous types of hazards that a hurricane or tropical storm can pose. They can cause extensive flooding and substantial damage, resulting in loss of life, homes, and businesses. Understanding the risks associated with storm surges is crucial to protect yourself, your family, and your property.
Types of Storm Surges
Storm surges are not only caused by hurricanes; they can also occur due to other weather conditions like nor’easters, strong tropical storms, and low-pressure systems. The severity of a storm surge depends on the wind speed, direction, and the size of the storm. A storm surge can be classified into different types based on their height relative to astronomical tidal levels:
1. Minor Storm Surge: Minor storm surges range from 1-3 feet above the normal tidal level. They generally cause some low-level flooding but do not cause extensive damage.
2. Moderate Storm Surge: Moderate storm surges range from 3-6 feet above the normal tidal level. They can cause moderate to significant flooding and can damage coastal buildings.
3. Major Storm Surge: Major storm surges range from 6-12 feet above the normal tidal level. They can cause widespread flooding, extensive property damage, and loss of life.
4. Extreme Storm Surge: Extreme storm surges range from 12 feet or higher above the normal tidal level. They can cause catastrophic damage, and the impact can last for days, if not weeks.
Understanding the Risks of Storm Surges
Storm surges can cause severe damage and devastation, mainly because of their high water levels and strong currents. Here are some of the significant risks associated with storm surges:
1. Flooding: Storm surges can cause widespread flooding of coastal areas that are normally dry. Floodwater can damage homes, businesses, and infrastructure, including roads and bridges.
2. Property Damage: Storm surges can damage or destroy buildings, boats, cars, and other personal belongings.
3. Loss of Life: Storm surges can be life-threatening, particularly for people who do not evacuate or are caught unprepared. Flooding, debris, and strong currents can endanger human lives.
4. Economic Impacts: Storm surges can have long-term economic impacts, as they can disrupt transportation, commerce, and businesses in affected areas.
5. Environmental Impacts: Storm surges can cause environmental damage, including erosion of beaches, destruction of natural habitats, and pollution caused by hazardous materials.
Protecting Yourself From Storm Surges
If you live in a coastal area prone to hurricanes or tropical storms, it’s essential to take measures to protect yourself and your property from the devastating impact of storm surges. Here are some steps you can take to prepare:
1. Evacuate: If you are in an area likely to be affected by a storm surge, evacuate immediately following the instructions of local authorities.
2. Secure Your Property: Ensure that your property is secure and prepared for the impact of a storm surge. This may include reinforcing doors and windows, moving valuables to higher ground, and turning off utilities.
3. Stay Informed: Stay updated on the latest weather forecasts and warnings from local authorities. This can help you make informed decisions about when to evacuate or take other protective measures.
4. Prepare an Emergency Kit: Prepare an emergency kit that includes essential items like food, water, medications, and first-aid supplies.
