From late Sept. through early Oct. 2021, two powerful storms churned over the Pacific and Atlantic Oceans: Typhoon Mindulle, which peaked as a Category 5 storm, and Hurricane Sam, a Category 4 hurricane and one of the longest-lived hurricane-strength storms on record over the Atlantic Ocean. While neither storm posed a direct threat to land, Mindulle brushed by eastern Japan, leaving heavy rainfall accumulations in the area near Tokyo. Despite the fact that neither storm made landfall, the storms’ slow-motion tracks across warm ocean waters allows an opportunity to observe how the strong winds

Although it only reached hurricane status for a brief period, Hurricane Nicholas made an impact on the northern Gulf Coast by bringing heavy rains to an area still recovering from the devastating effects of powerful Hurricane Ida, which made landfall in Louisiana just over 2 weeks earlier. Nicholas formed after a tropical wave passed over the Yucatan Peninsula and into the Bay of Campeche, providing a focus for shower and thunderstorm development. On the morning of Sunday September 12th, the National Hurricane Center (NHC) found that this area of storms had developed a closed circulation with

All eyes were on Hurricane Ida as it made landfall in Louisiana on Aug. 29, 2021, but many people were taken by surprise by the power of Hurricane Ida's remnants when they reached Virginia during the day on Sept.1 and New York City late at night on Sept. 1 into early morning on Sept. 2. The below animation shows the precipitation that fell during the entire lifecycle of Ida from before landfall in Louisiana through the impacts on New York City.

Hurricane Ida struck southeast Louisiana as a powerful Category 4 storm on Sunday, Aug. 29, 2021 - the 16th anniversary of Hurricane Katrina’s landfall in 2005. Ida brought destructive storm surge, high winds, and heavy rainfall to the region, and left over 1 million homes and businesses without power, including the entire city of New Orleans. The NASA / JAXA GPM Core Observatory satellite flew over the eye of Ida shortly before landfall at 10:13 a.m. CDT (1513 UTC), capturing data on the structure and intensity of precipitation within the storm.
