Severe Weather Alerts in South DakotaSouth Dakota Frequent Weather Alerts:
Drought, Severe Thunderstorms, Flooding, Winter Weather

South Dakota is one of the least populated states in the country, and due to its size, it has some of the swingiest weather patterns you can find in the entire country. As a result, both excessive precipitation and not enough precipitation cause problems for the state at different times.

Flooding and Thunderstorms

When it starts to warm up as winter ends, the snow in the mountains starts to melt and it can cause flooding in the foothills below. In 2010, there was over 2 feet of snow in the mountains, and when it melted in March, it caused severe flooding throughout the eastern part of the state.

From May to September, severe thunderstorms can be quite a common occurrence. The worst thunderstorms will often bring hail and, in some cases, tornadoes (not as frequently as the Tornado Alley states, however).

Drought

Certain parts of the state are drier than others, and increasing temperatures are causing droughts to become more frequent. In 2012, the state got less than 3 inches of rain during the summer (when the average per year is usually 15 to 25).
