Super Typhoon Irma
(international designation: 8126
name: Typhoon Anding
), was the 25th named storm, fourteenth typhoon, and second super typhoon of the 1981 Pacific typhoon season
. A powerful late season typhoon, Irma reached a peak wind speed of 155 mph (250 km/h) before hitting the northern Philippines

. The disturbance was moving northward and then westward as a cluster of thunderstorms. Because of the strong outflow from nearby Typhoon Hazen, the disturbance never was able to strengthen further. When Hazen moved off to the west, the tropical system was able to re-organize itself as a central circulation was defined on radar and satellite readings. On November 17, a Hurricane Hunter aircraft detected 35 mph (56 km/h) winds, which upgraded the disturbance to Tropical Depression 26W. 26W continued to move westward where it further strengthened and became Tropical Storm Irma as it bypassed Guam
