In the central and eastern Pacific Ocean on Saturday were two named storms, Fernanda and Greg, along with Tropical Depression Nine-E and Tropical Depression Ten-E. The two tropical depressions eventually went on to become Hilary and Irwin.
Meanwhile, the western Pacific Ocean had Noru, Kulap, Roke and Tropical Depression Eight-W all spinning in parts of that basin. Tropical Depression Eight-W would later become Tropical Storm Sonca.
Although it's not unheard of to see multiple tropical cyclones at the same time, this is impressive on any scale.
Eight tropical cyclones have not roamed the north Pacific Ocean simultaneously since 1974, according to Dr. Phil Klotzbach, a tropical scientist at Colorado State University.
