Typhoon Roger (198608) 的生命史始 at Northwest Pacific洋面, 整体路径呈现典型的NW toward Moving后转 toward NE的抛物线形态. formed初期 (7月13日) , 系统位 at 139.4°E附近, 稳定 toward NW direction推进, The latitude从16.7°N迅速N移至23°N, During同步W移. 在7月15日12时之前, Typhoon 中心持续 toward WNW, 逐渐逼近琉球群岛以E海域.
When the Center reaches 25.2°N, near 129.9°E, the Moving direction begins to change significantly, from NW toward gradually to N toward, then further toward NE. After July 16 at 12 a.m., as the latitude breaks 28°N, the length begins toward E to flow (from 129.2°E to 134.8°E) , marking Typhoon has Go to W wind-guided accelerated toward phase. During the entire life cycle, the Typhoon has not landfall any land, always at sea activity, finally at July 17 at 12 a.m. at 32.8°N, 134.8°E weakened into Tropical Storm and ended monitoring.

Compared to the same name History, Roger's Intensity performance in 1986 was in the middle. compared to the 18th Typhoon Roger (top Super Typhoon) in 1979, its Intensity was significantly weaker; but the best at the 19th Typhoon Roger (top Severe Tropical Storm) in 1989 and the 24th Typhoon Roger (top Typhoon) in 1982.
