Understanding the Threats of Storm Surge and Storm Tide
As coastal areas continue to be vulnerable to natural disasters such as hurricanes and tropical storms, it is important to be aware of the threats of storm surge and storm tide. While these two terms may seem interchangeable, they actually refer to two different phenomena that can have devastating effects on communities. In this article, we will explore the differences between storm surge and storm tide, what causes them, and what impact they can have.
What is Storm Surge?
Storm surge refers to the abnormal rise of water levels that occurs during a storm, particularly a hurricane or tropical storm. This rise in water levels is caused by the combination of low pressure and high winds that are associated with these weather events. Essentially, the wind pushes water ahead of it and the low pressure sucks water upwards, combining to create a dome of water that can be dangerous for coastal communities. Storm surge can be measured in feet above sea level, with some areas experiencing surges of 20 feet or more.
Because storm surge is often accompanied by high winds and heavy rainfall, the damage can be extensive. Homes, businesses, and infrastructure can be destroyed or severely damaged, and people can be injured or even killed. Storm surge can also lead to flooding, which can contaminate water sources, disrupt transportation, and cause further damage to property and infrastructure. In short, storm surge can be a deadly and destructive force.
What is Storm Tide?
Storm tide is similar to storm surge in that it refers to the rise in water levels that occurs during a storm, but it also includes the effects of the normal tides. In other words, storm tide is the combination of the storm surge and the expected tidal cycle. This means that the water levels can rise even higher than they would during just a storm surge. Like storm surge, the effects of storm tide can be devastating, and the damage can be extensive.
One key difference between storm surge and storm tide is that storm tide can be influenced by the location and time of the storm. For example, if a storm hits during high tide, the effects of storm tide will be even greater. Similarly, if a storm hits in an area where the normal tidal range is already high, the effects of storm tide will also be greater. This means that communities need to be aware not only of the potential for storm surge, but also the potential for storm tide.
Conclusion
As hurricane season approaches, it is important for coastal communities to be aware of the threats of storm surge and storm tide. While these two phenomena may seem similar, they actually refer to different processes that can have devastating effects on homes, businesses, and infrastructure. By understanding the differences between storm surge and storm tide, and taking appropriate precautions, communities can help minimize the damage and loss of life that can occur during these weather events.
Some of the precautions that can be taken include evacuating areas that are at risk of storm surge or storm tide, seeking higher ground if evacuation is not possible, securing property and infrastructure, and following the guidance of local authorities. By working together and taking appropriate steps, we can help mitigate the effects of storm surge and storm tide, and protect ourselves and our communities from these dangerous natural phenomena.
