Extreme Weather Events in Sioux Falls

Sioux Falls, like many places in the Midwest, is susceptible to extreme weather events. It's important to be aware of these potential hazards and know how to stay safe. Let's discuss some of the most common extreme weather events in our area:

Blizzards

Blizzards are severe winter storms characterized by heavy snowfall, strong winds (at least 35 mph), and low visibility (less than a quarter mile) for an extended period (at least three hours). These storms can be life-threatening, making travel impossible and causing power outages. Blizzards in Sioux Falls are not uncommon, and it's essential to be prepared. Here are some tips:

  • Stay Informed: Monitor weather forecasts and warnings from the National Weather Service.
  • Stay Home: If a blizzard warning is issued, avoid travel if possible.
  • Prepare Your Home: Ensure you have a supply of food, water, and medications. Have a backup heating source, such as a fireplace or generator, in case of a power outage.
  • Dress Warmly: If you must go outside, dress in layers and cover exposed skin.
  • Drive Safely: If you must drive, drive slowly and be aware of reduced visibility.

Thunderstorms and Tornadoes

Severe thunderstorms are common in Sioux Falls during the spring and summer months. These storms can bring heavy rain, strong winds, hail, and even tornadoes. Tornadoes, while less frequent than thunderstorms, are a serious threat in this region. It's crucial to know the difference between a tornado watch and a tornado warning:

  • Tornado Watch: Conditions are favorable for tornadoes to develop in the area.
  • Tornado Warning: A tornado has been sighted or indicated by radar.

If a tornado warning is issued, seek shelter immediately. The safest places to be are in a basement, a storm cellar, or an interior room on the lowest floor of a sturdy building. Stay away from windows and doors. Being prepared for thunderstorms and tornadoes is crucial for safety.

Flooding

Heavy rainfall can lead to flooding in Sioux Falls, especially in low-lying areas and near rivers and streams. Flash floods can occur suddenly and without warning, so it's essential to be aware of the potential for flooding during heavy rain events. Never drive or walk through floodwaters, as even a small amount of moving water can be dangerous. Turn Around, Don't Drown!

Extreme Heat and Cold

Sioux Falls experiences both extreme heat in the summer and extreme cold in the winter. Heat waves can be dangerous, especially for vulnerable populations such as the elderly and young children. Take precautions to stay cool during hot weather, such as drinking plenty of water, seeking air-conditioned spaces, and avoiding strenuous activity during the hottest parts of the day. Extreme cold can also be dangerous, leading to hypothermia and frostbite. Dress warmly in layers and limit your time outdoors during extremely cold temperatures.

  • Dress Appropriately: Dress in layers during the winter and wear lightweight, light-colored clothing in the summer. Protect yourself from the sun with sunscreen and a hat.
