The drought is largely driven by temperature, which increases the rate of evaporation, with some contribution from the lack of precipitation.

The drought began due to a strong La Niña developing by the summer of 2010 which brings below average rainfall to the southern United States. The effects of the La Niña could be noticed immediately as much of the south receives important rainfall during the summer, and this was the driest summer for Texas and Georgia in the 21st century thus far, and much of the south received record low ...
