The scale of the drought hitting the American West is beginning to crystallize as Nevada, New Mexico and Arizona experienced their driest year in terms of precipitation on record, according to the National Center for Environmental Information.

In Utah and California, it was the second-driest winter on record. For Wyoming, it was the third-driest ever. For Colorado, only three winters were ever drier in the 127-year history of record-keeping at the center.

“This is extreme,” said Peter Gleick of the Pacific Institute.
