Tropical Storm 23 strengthened to a named storm, Mininae, in late October 2009. Initially located northwest of Guam, the storm strengthened into a typhoon and headed toward the Philippines.
Although Mirinae was weakening, its winds maintained the classic spiral structure associated with well-organized tropical cyclones in this image of the storm’s wind structure on November 1, 2009.
Acquired October 27, 2009, this true-color image shows Tropical Storm Mirinae extending a long arm toward the east as the storm blows over the west Pacific Ocean.
