Preparing for Tornadoes in South Carolina

Because tornadoes can strike with little warning and cause significant damage and loss of life,  if you live in an affected area, you should take steps to prepare for these dangerous weather events. In South Carolina, the risk of tornadoes is particularly high during the spring months.

Preparation is critical since tornadoes can damage homes, businesses, and infrastructure. Strong winds, flying debris, and flooding can create hazardous conditions that can put people's lives at risk. The most effective way to protect yourself, and your family from tornadoes is to have a designated tornado shelter (in your home and at work), and also to have a plan in place before a tornado strikes.

One important aspect of tornado preparation is knowing the risks associated with tornadoes and understanding the warning signs. South Carolina has a robust system of tornado warning and response, including the use of sirens, weather radios, and emergency alerts. By staying informed and taking action when a warning is issued, residents can help minimize the damage caused by tornadoes.

Another critical component of tornado preparation is having an emergency kit on hand. This kit should include essential items such as water, non-perishable food, first-aid supplies, and a battery-powered radio. As mentioned earlier, a place to take shelter is crucial to your tornado action plan. If you don’t have a designated tornado shelter in your home or business, it’s important to know what the next best place to be is, whether that is in a community storm shelter or an interior room on the lowest level of your home.

By taking the time to understand the risks, develop a plan, and gather necessary supplies, residents can protect themselves and their property from the potentially devastating impacts of tornadoes.

Tornado Safety Tips

Here are some tornado safety tips that can help you stay safe in South Carolina:

  1. Monitor weather forecasts and be aware of the risk of tornadoes in your area. Sign up for local weather alerts and have a battery-powered radio or weather radio on hand to receive updates if power goes out. There are also location-based tornado alerts that tell you exactly when to take shelter.
  2. Develop an emergency plan for your family and make sure everyone knows what to do if a tornado warning is issued. Designate a safe place where you can take shelter during a tornado, such as a storm shelter or a small interior room on the lowest level of your home.
  3. Assemble an emergency kit with essential supplies, including water, non-perishable food, first-aid supplies, and a flashlight with extra batteries.
  4. Make sure outdoor furniture, decorations, and equipment are secured or brought inside before a tornado warning. Close and secure windows and doors, and check the condition of your roof when high winds are anticipated.
  5. If a tornado warning is issued, stay inside and take shelter immediately. If you’re in an area with no storm shelter, avoid windows, exterior walls, and doors, and protect your head with a helmet or a cushion. Go to the lowest level of the building.
  6. If you're in a vehicle, pull over to a safe location, get out, and lie down in a ditch or other low-lying area.
  7. Stay put: Wait until the tornado has passed and listen for emergency alerts before leaving your shelter. Avoid downed power lines and other hazards, and be cautious of debris and flooding.

By following these tornado safety tips, you can help protect yourself, your family, and your property from the potential dangers of tornadoes in South Carolina.

South Carolina Tornado Shelter  FAQs

Q: What causes tornadoes in South Carolina?

A: Tornadoes in South Carolina are typically caused by severe thunderstorms, which are produced when warm, moist air collides with cooler, drier air. As the two air masses collide, they create instability in the atmosphere, which can lead to the formation of tornadoes. South Carolina is part of "Dixie Alley." 

Q: When is tornado season in South Carolina?

A: The peak tornado season in South Carolina runs from March to May, although tornadoes can occur at any time of the year. During these months, the combination of warm, moist air from the Gulf of Mexico and cooler, drier air from the north can create the conditions necessary for tornadoes to form.

Q: What should I do if a tornado warning is issued?

A: If a tornado warning is issued, it's important to be prepared to take immediate action to protect yourself and your family. When your location is in the “polygon area” or when meteorologists have advised, it is time to seek shelter. If you're caught outside, seek shelter in a low-lying area, such as a ditch or culvert, and cover your head with your hands.

Q: What's the difference between a tornado watch and a tornado warning?

A: A tornado watch means that conditions are favorable for tornadoes to form in the area, while a tornado warning means that a tornado has been sighted or detected on radar and is imminent. If a tornado warning is issued, be prepared to take immediate action to protect yourself and your family. It's also a good idea to understand what the "polygon area" is for each storm. 

Q: Can tornadoes occur at night?

A: Yes, tornadoes can occur at any time of the day or night, although they are more difficult to see and detect at night. It's important to have a way to receive weather alerts even while you're sleeping, such as a weather radio or smartphone app.

Q: What should I include in a tornado emergency kit?

A: A tornado emergency kit should be part of your family's tornado plan and should include essential items such as water, non-perishable food, a first aid kit, a flashlight, extra batteries, a weather radio, and any necessary medications. It's also a good idea to have chargers for your phones.

Q: How do I prepare my home for a tornado?

A: To prepare your home for a tornado, make sure to secure loose objects such as lawn furniture and debris. Trim trees and branches near your home, and check the condition of your roof. It's also a good idea to designate a safe room or shelter area in your home, such as a basement or interior room on the lowest level. Ideally, it's also possible to install a residential tornado shelter approved by the NSSA and Texas Tech Wind Institute.

Q: What's the difference between a tornado and a hurricane?

A: A tornado is a small, rapidly rotating column of air that touches the ground, while a hurricane is a large, rotating storm system that forms over the ocean and can cause widespread damage and flooding. While both can be deadly, tornadoes are typically smaller in scale and occur more frequently than hurricanes. It is also possible for hurricanes to spawn tornadoes.

Q: How common are tornadoes in South Carolina?

A: South Carolina averages around 15-20 tornadoes per year, although the number can vary from year to year. Tornadoes can occur in any part of the state, but are most common in the northern and central regions.

Q: What should I do after a tornado has passed?

A: After a tornado has passed, it's important to stay inside and avoid hazards such as downed power lines and debris. If you're trapped, try to signal for help with a whistle or other loud noise. Check on your family and neighbors, and listen to local authorities for information on recovery efforts. Some tornado alert systems, like StormWarn, are also designed to deliver an "all clear" once the danger is over.
