On February 15 - 16, 2025, a powerful storm moved across the US Southeast. The storm brought damaging winds, destructive flash floods, and torrential rain to many parts of Tennessee and Kentucky. On April 2, 2025, an impactful storm and waves of thunderstorms occurred across West and Middle Tennessee. The rainfall led to catastrophic flash flooding and moderate to major river and area flooding. The unexpected weather conditions led to 4,100 statewide power outages on April 7, though there were fewer than 70,000 outages on April 5.
Regardless of where you live in the USA, it is essential to prepare for unexpected flooding. But how to prepare for floods? You need to have the right emergency supplies, a ready evacuation plan, and a backup source to keep essentials powered. Jackery Solar Generators are essential home backup power solutions, capable of powering most appliances, such as refrigerators, lights, sump pumps, etc. Read the guide to learn about the government's flood preparation tips, how to check flood risk zones, etc., to better prepare for the floods.
Key Takeaways
- Tennessee's recent floods highlight the need for year-round preparedness, especially for those who live in flood-prone areas.
- One way to check the flood risk and receive a flash flood warning is to use FEMA's Flood Map Service Center.
- Preparing for floods includes installing sump pumps with battery backup power, using waterproofing sealants on basement walls, and preparing an emergency kit.
- Jackery Solar Generators are ideal home battery backup solutions that can power most essential household appliances during outages caused by floods or other natural disasters.
Understanding the Types of Floods
Flooding means overflowing of water onto land and can happen during heavy rains, snow melting, etc. They can occur within minutes and may last days, weeks, or even longer. In fact, according to the NSSL (NOAA National Severe Storms Laboratory), floods occur in every US state and kill more people each year than hurricanes, tornadoes, or lightning. Here are different types of floods as per the NSSL:
River Floods: When the water level rises on the top of the banks with excessive rain from tropical systems, it causes river floods. The floods are also accompanied by persistent thunderstorms over the same area for extended periods of time.
Coastal Floods: A coastal flood is generally caused by a higher-than-average high tide. It is accompanied by heavy rainfall and onshore winds that worsen the effects of the floods. Some regions that experience coastal floods include South Carolina, Savannah, and Georgia.
Storm Surges: They are the abnormal rise in water level in coastal areas. Such storm surges are caused by severe storm's wind, low atmospheric pressure, and waves. Along the coast, they are often the greatest threat to life and property.
Flash Floods: Flash floods are usually caused by excessive or heavy rainfall in a short period of time, less than six hours. While they usually occur within a few minutes or hours of excessive rainfall, they can also occur even if no rain has fallen.
Inland Floods: If the intense precipitation falls over a short period, moderate precipitation accumulates over several days, or a river overflows due to an ice or debris jam, it leads to inland flooding. Common examples of inland floods include Hurricane Floyd.
How to Check Your Flood Zone
One simple way to check flood zones is to use the FEMA Flood Map Service Center (MSC). It is the official online tool where you can find all flood hazard mapping products. You need to visit the FEMA Flood Map Service Center (MSC) to find the official flood map of your area and the National Flood Hazard Layer data.
You can also sign up for the community's warning system. For example, the Emergency Alert System (EAS) and National Oceanic and Atmospheric Administration (NOAA) Weather Radio also provide emergency alerts. In addition, the National Risk Index is another easy-to-use tool that shows communities at high risk of flooding.
Note: One important thing to note is that homeowners' insurance policies do not cover flooding. So, make sure to get flood coverage under the National Flood Insurance Program (NFIP).
How to Prepare Your Home for a Flood
Floods don’t always arrive with a warning. Preparing your property ahead of time is one of the smartest investments you can make in terms of money and peace of mind. Here's how to prepare your home for a flood, recommended by FEMA, CDC, the Red Cross, and other government resources:
Install Sump Pumps With Backup Battery Power
A sump pump is your first line of defense if floodwaters seep into your basement or crawl space. Installing a sump pump battery backup ensures the appliance keeps running even when the grid goes down. It's a small upgrade with huge returns, especially during flash floods or prolonged storms.
Elevate Electrical Systems, Furnaces, and Water Heaters
Floodwaters and electricity don’t mix. That’s why it is recommended to raise your electrical panels, outlets, switches, and heating systems above potential flood levels, typically at least a foot above base flood elevation. It’s a practical way to protect major systems from water damage and reduce fire risks, all while helping you recover faster after a disaster.
Use Waterproofing Sealants on Basement Walls
If you’ve got a basement, seal the cracks before the storm comes. Applying waterproofing sealants to your walls and foundation helps reduce seepage during heavy rainfall. It won’t stop a full-scale flood, but it can buy you valuable time and minimize long-term water damage from leaks and groundwater pressure.
Install Check Valves to Prevent Floodwater Backup Into Drains
Sewage backup is one of the most dangerous flood risks. Installing check valves on your home’s plumbing system prevents floodwater from flowing backward through your drains, sinks, and toilets. This small plumbing modification can prevent major health hazards and costly cleanups.
Landscape to Direct Water Flow Away From Your Home
The slope around your home matters more than you think. Grading your yard so water naturally flows away from your foundation can prevent pooling and structural damage. You can also use gravel beds, rain gardens, or swales to manage runoff. It’s a simple strategy that turns landscaping into a functional flood defense.
Create an Emergency Supply Kit
When a flood warning hits, there’s no time to think, as you just need to act. Having a written checklist of what to do (turn off utilities, grab your emergency kit, secure valuables) can save time and prevent panic. You can post it somewhere visible and review it with your household so everyone knows the drill when it matters most.
In addition, you need to prepare an emergency kit with emergency supplies in your car, including food, water, flares, a first aid kit, a fire extinguisher, booster cables, maps, tools, portable power stations, sleeping bags, etc. Jackery Portable Power Stations can be packed in your car to ensure you have power on the go.
Jackery Solar Generators for Flood Preparedness
