Tropical Storm Mindulle formed near the Mariana Islands in the Pacific Ocean on the morning of September 23, 2021. The Moderate Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Terra satellite acquired a true-color image of the storm on that same day. At that time, convective bands of the organizing storm reached over Guam and the Northern Mariana Islands.
At 1500 UTC (11:00 a.m. EDT) on September 24, the Joint Typhoon Warning Center (JTWC) advised that Mindulle was carrying maximum sustained winds of 69 mph (111 km/h) with gusts to 86 mph (138 km/h). At that time, Tropical Storm Mindulle was located about 963 miles (1,550 km) southeast of Kadena Air Force Base and was tracking northward.
The storm is in favorable environment, with low wind shear and warm sea surface temperatures. The JTWS expects the storm to rapidly intensify to reach about 150 mph (241 km/h) by September 27. That would place it as a strong Category 4 storm on the Saffir-Simpson Hurricane Wind Scale. After that time it should begin to weaken as it tracks towards Japan.
