in early September 2007.
on September 10 and moved northwestward, slowly increasing in organisation. The Japan Meteorological Agency
began monitoring the system as a tropical depression the next day. The depression continued to organise and strengthen, and the Joint Typhoon Warning Center
issued a Tropical Cyclone Formation Alert
on it during the afternoon of September 12, and began issuing advisories on Tropical Depression 12W an hour later. The JMA followed suit early on September 13 and initiated advisories on the system; PAGASA
named the system Falcon shortly after. The depression continued to intensify, and the JMA upgraded it to Tropical Storm Nari later that morning. The storm then underwent rapid intensification
that afternoon and evening, strengthening from a tropical depression to a typhoon in just 18 hours. The JMA upgraded Nari to a severe tropical storm late that afternoon, and by late that evening, Nari was upgraded to a typhoon. Nari reached its peak on September 14, and began weakening soon afterwards. It turned extratropical right after landfall

United States Marine bases located in Okinawa were placed under Tropical Cyclone Condition of Readiness-3 as Nari approached the islands on September 15. Aircraft and important equipment were secured to prevent damage to them. Several of the more important aircraft were transported to other locations throughout the Pacific. Working parties were scrambled to quickly assess and repair damage following the typhoon. About 30 marine soldiers were placed on "Typhoon Watch". They were to ride out the storm at the Foster headquarters building until Tropical Cyclone Condition of Readiness-1 had been sounded. At that time, they were to survey the area for signs of damage.

Total precipitation in Okinawa was estimated to have reached 120 mm (6 in), with rainfall rates peaking at 45.5 mm (1.8 in) per hour. At least 4,500 residences were left without power throughout all the islands, most of which were on Kumejima. In Naha City, a wall collapsed due to the rain but caused no injuries. Cars were reportedly flipped over in Kumejima Town where the worst damage was dealt. Numerous buildings lost their windows and numerous trees were knocked down.
