Preparations and impact

On September 23, Typhoon Yagi passed directly over the resort island of

which has a population of about 2,000. The cyclone brought winds up to , making it the strongest typhoon in 20 years to hit the island. About 1,000 of the 1,270 homes were without power during the height of the storm. About 150 residents evacuated to local shelters during the storm to escape the high winds and heavy rains. At least one structure was destroyed and numerous others sustained damage. The storm reportedly produced torrential rains, but there are no known measurements. Several homes had their roofs blown off and windows broken. Street lamps were knocked down by the strong winds produced by Yagi. Ferry service for several ports was cancelled for 29 days following the typhoon. Fallen trees knocked down power lines and cut communications. Some homes were reported to have lost water pressure also. The storm passed close to

on September 22, with the island being within the range of winds. No loss of life or injuries were related to Typhoon Yagi.
