Hurricane Storm Surge: Common Mistakes to Avoid

Hurricane storm surges are among the most perilous threats during a hurricane, often causing more damage than the storm's winds. Understanding these surges and avoiding common mistakes can significantly enhance your safety.

What Is a Hurricane Storm Surge?

A storm surge is an abnormal rise in sea level caused by a storm, over and above the predicted astronomical tides. This surge can lead to extreme flooding in coastal areas, especially when it coincides with normal high tide, resulting in storm tides reaching up to 20 feet or more in some cases. (nhc.noaa.gov)

Why Are Storm Surges So Dangerous?

Storm surges can inundate coastal regions, causing severe flooding and erosion. The force of the water can destroy buildings, wash away roads, and lead to significant loss of life. For instance, during Hurricane Katrina in 2005, at least 1,500 people lost their lives, many due to storm surge-related flooding. (weather.gov)

Common Mistakes to Avoid During a Storm Surge

1. Underestimating the Timing of the Surge

Storm surges can begin to rise a day before the storm hits, cutting off escape routes when low-lying highways are flooded. (wunderground.com) It's crucial to evacuate early to avoid being trapped by rising waters.

2. Ignoring Evacuation Orders

Evacuation orders are issued to save lives. Ignoring these orders can lead to being caught in life-threatening conditions. Always adhere to evacuation instructions from local authorities.

3. Relying Solely on Wind Speed for Safety

Many people focus on wind speed when assessing hurricane danger, but storm surge poses a greater threat. Even a Category 1 hurricane can produce a significant surge. It's essential to consider all aspects of the storm's impact. (nhc.noaa.gov)

4. Misunderstanding Local Vulnerabilities

Coastal areas with gently sloping ocean floors are more susceptible to higher storm surges. For example, the Gulf Coast is particularly vulnerable due to its wide and shallow continental shelf. (nhc.noaa.gov) Being aware of your area's specific risks can aid in better preparation.

5. Failing to Prepare an Emergency Kit

An emergency kit should include essentials like water, non-perishable food, medications, flashlights, batteries, and important documents. Having a kit ready ensures you're prepared for power outages and other disruptions.

How to Protect Yourself and Your Property

  • Stay Informed: Monitor weather updates and heed warnings from local authorities.

  • Develop an Evacuation Plan: Know multiple routes out of your area and have a designated meeting place.

  • Elevate Utilities: If possible, raise electrical appliances and utilities above potential flood levels.

  • Install Flood Barriers: Use sandbags or other barriers to protect entry points to your home.

  • Secure Outdoor Items: Bring in or secure outdoor furniture and decorations to prevent them from becoming hazardous projectiles.

Conclusion

Hurricane storm surges are a formidable threat, but with proper preparation and awareness, you can mitigate their impact. Avoiding common mistakes and taking proactive measures can safeguard your life and property during these events.
