Island power failed at 1300L on the 3rd due to some lines being ripped off the poles by high winds. Island power was restored at 1600L on the 5th.Northern clockwise through southern shores of the main Island of Yap was heavily destroyed, mainly due to the thunderous storm surge pounding the shoreline. Private dwellings along the shore was washed away. Even some concrete buildings close to the shoreline was destroyed by the surf. Destiny Hotel in Gilman was completely demolished. In some areas, the strong tidal surge went inland as far as 600 feet. Part of the roof at the Yap International Airport terminal was ripped off. The boarding area, check-in area, waiting area, and arrival area flooded with rain water and debris. Most of the roads and causeways in Colonia were under 4 to 5 feet of water. The whole length of theColonia Park Seawall was damaged by high tide and strong currents from the storm. Numerous trees were damaged or knocked down across Yap. The fallen trees blocked many roads. On the southern most tip of Yap much damage was done to food crops and residential areas. The southeastern side of the tip had about 95 % damage from the shoreline up to 400 meters inland. The western side of the southern tip only had 30 % overall damage. The Church of St. Francis Assisi in Guroor near the southern tip of Yap lost part of its stone platform due to the strong currents from the storm surge. In Magachgil to the south of Guroor, many coconut trees were either uprooted or broken in half. Many Taro crops had salt water intrusion caused by the sea inundating them. Those Taro patches that were not destroyed by the inundation had plants die later on due to salt water intrusion into the roots or even from salt spray.

Some windgust were observed on the northern islands of Kay Angle. No damage was reported. Indirect effects of the Typhoon. The damage to the food crops on some of the small islands in Yap and Chuuk States caused hardships on the people there. With Taro crops filled with salt water and banana and breadfruit trees destroyed or damaged many people went hungry on the small islands. A death on Nomwim Atoll in Chuuk State has been attributed to health problems caused in the wake of Typhoon Mitag. Some of the islands only had food for one to two weeks.A man in Palau died as an indirect result of the storm. 36 year old Akino Isamu was helping his friend to cut down a coconut tree in Peleliu. They thought it posed a danger to a house if strong winds from the typhoon reached Palau. When the tree was cut and started to fall, Akino tried to avoid it but guessedwrongly. The tree fell directly on him, pinning him to the ground.
