High Quality Content by WIKIPEDIA articles! Typhoon Yagi (international designation: 0614; JTWC designation: 16W) was an intense typhoon, the strongest of the 2006 Pacific typhoon season, which reached the equivalence of Category 5 on the Saffir-Simpson Hurricane Scale. Forming out of a tropical depression on September 16, Yagi quickly strengthened as it executed a slow clockwise loop over the open waters of the western Pacific Ocean. On September 19, Yagi strengthened into a typhoon as a subtropical ridge steered the storm towards the west. Two days later, the storm reached its peak intensity with winds of 195 km/h (120 mph 10-minute winds) with a minimum pressure of 910 hPa (mbar). The typhoon gradually weakened as it recurved towards the northeast and was downgraded to a severe tropical storm on September 24 and became extratropical the next day. The storm was last noted near the Aleutian Islands on September 27. The typhoon caused severe damage on the island of Chichijima but no injuries were reported as a result of the storm.
