The remnants of Melor were absorbed by a newly-formed extratropical cyclone near Alaska, which strengthened significantly and impacted the West Coast of the United States on October 13.

[1] During the next day, the system gradually developed, as satellite imagery showed a low-level circulation center had begun to form.

On the evening of that day, due to a tropical upper tropospheric trough (TUTT) that was providing good outflow for the system and low level vertical wind shear with a favorable environment, JTWC released a Tropical Cyclone Formation Alert, noting that fragmented banding was now wrapping into the western side of the low level circulation center.

The JTWC followed suit later that day, assigning the designation of 20W to the system, despite it having a poorly defined low level circulation center.

Melor moved with wind speeds of 252 kilometers per hour (156 mph) and bore down on the island of Minami Daito.

Typhoon Melor, which was located at 512 km (318 mi) from the southeast of Naha in Okinawa on October 6 at 12 p.m. Japan time, was predicted to be on a path for Tokyo.

[13] As a weakened typhoon, Melor made landfall in Japan on October 7 with wind gusts over 155 km/h (100 mph), causing massive power outages.

[15] Another 64 people were injured, according to local media reports, after Melor reached landfall in Japan's Aichi prefecture early Thursday morning.

[citation needed] Typhoon Melor landed south-west of Tokyo on the main island of Honshū on Thursday, October 8, causing at least two deaths and cutting electricity to thousands.

[citation needed] The storm was expected to drift off the country's eastern coast into the Pacific Ocean by Thursday evening.

An official at Japan's meteorological agency said the storm weakened as it moved along the eastern coast, preventing heavier damage.

[citation needed] The typhoon brought wind speeds of about 160 kilometers per hour while dumping 30 centimeters of rain in some regions, according to Japan Meteorological Agency.

[17][18] On October 14, 2009, the extratropical cyclone that had absorbed Melor's remnants impacted California, and broke several rainfall records.
