SOUTH DAKOTA – A developing Super El Niño in the Pacific Ocean could bring a warmer and drier-than-normal winter to western South Dakota, creating new concerns for ranchers already dealing with years of drought.
Meteorologists say there is a better than 90 percent chance El Niño conditions will develop this winter, with a strong likelihood the event could intensify. Historically, strong El Niño patterns have steered storms south of the region, often resulting in less snowfall and below-average precipitation across western South Dakota.
The outlook comes as much of the region remains dry. The Rapid City area has received only about half of its normal precipitation this year, while reservoir levels and grazing conditions continue to reflect ongoing drought concerns.
Ranchers say the uncertainty is forcing difficult decisions. Some producers are reducing herd sizes to conserve grazing resources and avoid rising feed costs. The nation’s cattle herd is already at its lowest level in decades, largely due to drought conditions across major cattle-producing regions.
Forecasters say there is still a chance for some improvement this fall, but confidence in precipitation forecasts drops significantly heading into spring, when moisture is most critical for grass growth and livestock production.
