Spencer is a small city located in McCook County, South Dakota, in the United States. In 2020, about 136 people lived there. Spencer is known for a powerful tornado that hit the city in 1998. This event caused a lot of damage and changed the town significantly.

History of Spencer

Spencer was founded in 1887. This happened when a railroad line was built to reach that area. The city was named after H. Spencer, who was an important official for the railroad company. A post office opened in Spencer in the same year, 1887. Spencer officially became a city in 1917.

The 1998 Spencer Tornado

On May 30, 1998, Spencer was hit by one of the strongest and most destructive tornadoes in South Dakota's history. This tornado was rated as an F4, which means it had incredibly powerful winds. It started northwest of Farmer and moved east-southeast.

As the tornado approached Spencer, scientists using a special mobile Doppler weather radar called "Doppler on Wheels" measured its winds. They found that the winds inside the tornado were blowing as fast as 264 miles per hour! This is faster than many race cars. The tornado caused a lot of damage and sadly, six people lost their lives.

After the tornado, many people moved away from Spencer. The city's population dropped from 315 people to just 145 by April 1999. The population has stayed around that number since then.
