A drought is an extended period of months or years when a region notes a deficiency in its water supply. Generally, this occurs when a region receives consistently below average precipitation. It can have a substantial impact on the ecosystem and agriculture of the affected region. Although droughts can persist for several years, even a short, intense drought can cause significant damage and harm the local economy. While wet and snowy weather has dominated the western U.S., persistent drought conditions are likely to linger in the Southern Plains and Southeast through mid to late spring, according to NOAA’s National Weather Service. La Niña has kept storms and most of their precipitation in the north, leaving the South drier than normal.
