Typhoon Melor (2009)
Typhoon Melor, known in the Philippines as Typhoon Quedan, was the second category 5 typhoon in 2009. It interacted with Typhoon Parma in the first week of October southeast of Taiwan.
==Meteorological history==
On September 28, an area of convectional cloudiness formed 370 km (250 mi) to the northeast of Pohnpei. Satellite imagery showed a Low Level Circulation Centre had begun to form. On the evening of September 28, due to a TUTT that was providing good outflow for the system and low level vertical wind shear with a favorable environment, the JTWC issued a Tropical Cyclone Formation Alert. Early on September 29, both JMA and JTWC upgraded the system into a tropical depression. Early on September 30, JMA reported that the depression had intensified into a tropical storm and assigned its international designated name, Melor. At the same time JTWC also classified the depression as a tropical storm. Early on October 1, Melor intensified further from a severe tropical storm into a typhoon. Intensification continued, and by the afternoon of the same day the JTWC reported that Melor had intensified into a Category 1-equivalent typhoon. In just four hours, it intensified rapidly to a Category 3-equivalent typhoon, and continued to track towards northeast Luzon. Early on October 2, it strengthened to a Category 4-equivalent typhoon. After levelling out in intensity, it strengthened again on October 3. Early October 4, JTWC reported that Melor had intensified to a Category-5 equivalent super typhoon, with JMA reporting a central pressure of 910 hPa and winds of 205 km/h. On October 5, PAGASA allocated the name Quedan to the typhoon as the storm moved into Philippine's area of responsibility. It interacted with Typhoon Parma in Parma's second landfall in the Philippines. By the midday of October 8, Melor made landfall on Japan. After landfall, JMA downgraded Melor into a severe tropical storm, while the JTWC downgraded it into an extratropical storm. Late on October 11, the extratropical remnants of Typhoon Melor were completely absorbed by a newly formed extratropical storm to the north, near Alaska. The new extratropical storm then strengthened into a powerful storm, which then began to impact the west coast of the United States, late on October 13.
