Storm surge from hurricane Ike
When most people hear the word “hurricane” they more than likely think of one thing: wind. Next, they probably ask, “what category is it?” While these aspects of a hurricane are certainly important, I believe a larger issue is being overlooked and put on the back burner until it is too late: the threat from water.
We can see the wind or, more accurately, the effects of wind, as soon as it starts blowing. The harder it blows, the more dramatic the effects are on the things around us such as trees and flags. This registers instantly in our brains and we can understand it because we can see it. Therefore, if the hurricane has 100 mph wind, while you might not necessarily grasp the concept of just how much energy that means, you do generally understand that it could damage your property.
Water, on the other hand, is seemingly tougher to conceptualize. The forecast as a hurricane approaches calls for 10-15 inches of rain. What does that mean? We can all visualize a ruler which is 12 inches but what exactly is 12 inches of rain going to do at your home or business? A lot of that depends on how fast the rain rates add up and what the drainage is like in and around your property.
The real danger comes when too much rain falls too fast and streams and creeks become swollen, flowing over the roadways and inviting disaster. There is no way to predict when and where this will occur with any degree of accuracy. As we saw again with Matthew last October in North Carolina, despite repeat events (Floyd in 1999 and the historic rains in NC/SC in 2015) people continue to drive across flowing water as if they are immune to the laws of physics. Too often, they are dead wrong. I’ll come back to this topic later.
Storm surge is about as dangerous and destructive as it gets yet few people truly understand what it actually is. Historically, storm surge has taken more lives than any other effect and it is the sole reason that evacuations are ordered for coastal areas. That’s right, we do not evacuate for wind – it’s the water. While it is true that you do not want to remain in an unsafe structure during the high winds of a hurricane, modern building codes should protect a vast majority of the people in harm’s way but water is a different story.
Moving water has an enormous amount of force behind it. Waves crashing ashore bring with them enough energy to bulldoze structures along the immediate beachfront. Those crumbled structures now become solid pieces of the surge and waves and act to batter and break up even more man-made structures. The end result is massive damage along the coast and the potential for loss of life.
Instead of yammering on and on about how bad it can get, I want to focus on a solution. There is something that can be done to completely eliminate the loss of life that we are seeing because of hurricanes (tropical storms too) and the effects of water.
The first step is understanding the risk where you live. As I said, evacuations are planned based on potential storm surge flooding and this is done well in advance of any hurricane. You need to take the personal responsibility of asking questions about where you live or work. Do not rely on someone to do it for you. Use social media and the Internet as a whole to your benefit. Go online and ask, “Do I live in an evacuation zone?” Do not stop asking until you find the answer.
Once you know your risk to storm surge, you can then make an appropriate plan. Make the decision now that if your evacuation zone is called to evacuate, you do it, no questions asked. No waiting to see what the hurricane does tomorrow or what Bob and Margaret next door decide to do. This is your one chance to get it right and not regret it later. Do not put first responders at risk during the storm by calling them begging to be saved. That is irresponsible and selfish and should never be an issue if people followed the plan and left when told to do so.
While it is true that most people who evacuate come home to little or no damage, it is best to err on the side of caution and leave when told to do so. I realize more than you know how stressful it is and that it is not something to be taken lightly. That is why I make the case for planning now and making the choice now that you will in fact go when told to go. It takes planning and that needs to be done before hurricane season ever begins.

Fresh water flooding is a killing agent that seems to never get better. Time and again people are seen and captured on video trying to cross flooded roads – often times failing and losing their lives. This is absolutely unacceptable and needs to stop. Again, it puts rescuers at great risk and drains resources that could be used elsewhere.
I am going to make it real simple. Hurricanes and tropical storms mean rain and a lot of it. When it rains, roads flood. I don’t care what kind of vehicle you own or how many times you have been down “that road”, it doesn’t matter if the water is too high or too swift; you will get swept away. Don’t do it. Stay home and avoid driving until things get better.
As the hurricane season nears, I challenge you to do more to learn about the impact of water from tropical storms and hurricanes. Wind is the big headline but often times at the cost of losing sight of how water can be both deadly and destructive. We need it to survive but it can turn against us in nightmarish ways.
Technology can only get us so far. We can see the hurricanes before they even form thanks to incredible advances in computer models. Now it is time to put our common sense to use and realize once and for all that sometimes we have to relent and do the right thing. That means evacuating when told to do so and not driving across flooded roads. It’s 2017 people, let’s act like we’ve been here before and actually learned something from the past. If not, well, you know what happens if not….
