There were eight separate tropical cyclones active at one time on July 22 over the north Pacific Ocean.
This was a first in more than four decades.
Although it’s not unheard of to see multiple tropical cyclones at the same time, this is impressive on any scale. The north Pacific Ocean pulled off an impressive feat with eight tropical cyclones spinning at one time Saturday, July 22, something that hasn’t been accomplished in more than four decades.
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.
The majority of the eight tropical cyclones observed Saturday will never affect land directly. The exceptions are Roke, which brought heavy rain to southeast China, and Sonca which could soak China’s Hainan Island.
Eight tropical cyclones have not roamed the north Pacific Ocean simultaneously since 1974. In comparison, there have been as many as five active Atlantic tropical cyclones at one time, from September 11-12, 1971.
