A Trio of Tropical Cyclones in the Pacific - NASA Science

NASA said El Niño helped drive above-normal Pacific activity while the Atlantic remained quiet, with only five named storms and no hurricanes.

  • On September 1, NASA's EPIC satellite captured three tropical cyclones churning simultaneously in the Pacific: Lowell, Karina, and Marie, reflecting the season's intense activity.
  • El Niño, brewing in the Pacific during spring 2026, contributes to above-normal activity in the northeastern and central Pacific basins while suppressing Atlantic storms by shifting circulation patterns.
  • Lowell reached category 5 strength on September 2, while Karina hit category 4, creating a rare simultaneous occurrence; the Northeast Pacific basin's ACE index hit 130, about 50 percent above normal.
  • Conversely, the Atlantic basin remains notably quiet under unfavorable wind shear conditions, producing just five named storms with an ACE index of 4.4—about 9 percent of normal as of September 3.
  • Tropical Storm Edouard recently brought torrential rains to Louisiana and Texas, downing trees and power lines; experts recommend using the "Events" tab on NASA's Worldview browser to track current hurricanes.

The Pacific is experiencing an unusual meteorological episode: three tropical systems, Lowell, Karina and Marie, are active at the same time. Such a phenomenon has not been recorded since 2015, when hurricane Kilo, Ignacio and Jimena formed simultaneously in this area. Meteorologists are closely monitoring the evolution of storms, under conditions where Hawaii and the southern coast of California could feel some of their effects.
