Tulip in spring snow (DI00800)
A tulip is surrounded by heavy snow that struck Boulder, Colorado, in April 1998, toward the end of the record-setting 1997-98 El Nino. El Nino tends to increase precipitation across the South and Southwest and decrease it across the northern tier of U.S. states. In Colorado, the effects of El Nino are less clear-cut and more complex.
