A NASA Earth Observatory report published September 4, 2026 described an image captured at 1:14 p.m. Pacific Daylight Time on September 1, 2026, showing three tropical cyclones over the Pacific at once: Lowell, Karina and Marie. The EPIC camera on the DSCOVR satellite also recorded Tropical Storm Edouard over Louisiana and Texas shortly after landfall.

According to the report, Lowell reached category 5 strength for several hours on September 2, while Karina reached category 4, a rare simultaneous pairing. Marie was still a tropical storm when imaged. As of September 3, the Northeast Pacific had produced 15 named storms and six hurricanes, well above normal, while the Atlantic had five named storms and no hurricanes. The Atlantic ACE index stood at 4.4, about 9 percent of normal, and the Northeast Pacific ACE at 130, about 50 percent above normal, per Colorado State University statistics cited by NASA.

National Weather Service meteorologists said some areas received 15 to 24 inches (38 to 61 centimeters) of rain from Edouard.
