High Quality Content by WIKIPEDIA articles! Typhoon Soulik (international designation: 0618; JTWC designation: 21W) was the 18th named storm and 11th typhoon of the 2006 Pacific typhoon season. Soulik formed out of an area of disturbed weather over the open waters of the western Pacific Ocean during early October 2006. The Japan Meteorological Agency (JMA) designated the system as a tropical depression on October 8 and later a tropical storm the next day. The Joint Typhoon Warning Center (JTWC) followed suit shortly after, classifying the system as Tropical Storm 21W. The storm gradually intensified into a typhoon on October 12 before nearly stalling close to Iwo Jima. On October 14, the storm began to accelerate and weaken due to increasing wind shear. Around 1200 UTC on October 16, Soulik transitioned into an extratropical cyclone before dissipating the next day. Typhoon Soulik had only minor effects on land throughout its existence, despite passing very close to Iwo Jima at peak intensity.
