Drought is a part climate, just like hurricanes, thunderstorms, and tornadoes. Unlike the other hazards that affect the state, droughts can impact large areas and last for months, even years. Drought is the lack of soil moisture over a period of time. This lack of moisture can be due to reduced precipitation, increased evaporation and/or transpiration, or higher temperatures. It can also be caused by a combination of all of these causes.
One of the worst droughts to impact the entire state occurred in 1925, when record low streamflows were observed. The lack of rainfall affected water and power supplies and many wells failed. More modern day droughts that have impacted South Carolina are the Drought of 2007-2008 and Drought of 2011.
