What is a Storm Surge?
A “storm surge” is a phenomenon that can happen in coastal areas or anywhere that borders a large body of water, such as Lake Ontario or one of the other Great Lakes. During periods of high wind and air pressure, the water level will begin to rise and cause high waves. A storm surge is often seen during periods of high winds, hurricanes, nor’easters (storms or winds blowing from the Northeast), or intense winter storms and can happen within a fairly short amount of time.
How Do Storm Surges Cause Flooding?
The air pressure and winds that form over the water during a storm surge creates large waves, effectively driving up the water level. These waves can cause the lake to spill over into surrounding, low-lying areas and cause significant flooding. The likelihood of this happening goes up significantly if the storm surge occurs at the same time as high tide.
Flooding from a storm surge does not have to be from the lake or ocean directly. The storm surge may cause connecting rivers to flood, or it can combine with any river flooding already being caused by the same storm.
What Kind of Flood Damage Can a Storm Surge Cause?
The inland flooding from a storm surge has been known to damage roads and bridges. With this kind of power, it is not an understatement to say a storm surge can cause catastrophic flood damage, especially if your property is low-lying. The most dramatic example of the kind of damage a storm surge can cause would be Hurricane Katrina from 2005. Most of the damage wrought by the hurricane was the result of the water levels rising due to a storm surge rather than the winds and force of the hurricane directly.
How to Protect Yourself from a Storm Surge
The good news is that any weather phenomenon capable of causing a storm surge is going to get noticed by meteorologists in advance. This will give you some advanced notice so that you can take certain preventative steps to minimize potential damage to your property.
- Check your property for any areas vulnerable to damage or infiltration from flooding or any potential dangers that could be exacerbated by flooding.
- Local emergency officials can provide you with information on how to properly sandbag your home to keep water out.
- Move any important documents to your topmost floor or store them with a friend or family member who does not live in an area that can be affected by a storm surge.
- Keep an ear on the radio in case an evacuation order comes in.
- Keep an emergency kit handy and have an evacuation plan in place with your family.
- If advised by local officials, turn off your gas and electricity.
- Do not drive through flood waters.
