On Oct. 27 at 0900 UTC (), Tropical Storm 1S had maximum sustained winds near 39 mph, the threshold for tropical storm strength. It was far away from land areas, some 825 nautical miles southeast of the island of Diego Garcia, near 12.5 South and 85.1 East. It was encountering a stronger vertical wind shear, so it has been unable to strengthen and is going to start running into cooler waters will which further reduce its chance to intensify.
