After passing Guam, Tip rapidly intensified and reached peak sustained winds of 305 km/h (190 mph)[nb 1] and a worldwide record-low sea-level pressure of 870 hPa (25.69 inHg) on October 12.

U.S. Air Force aircraft flew 60 weather reconnaissance missions into the typhoon, making Tip one of the most closely observed tropical cyclones.

[1] Rainfall from Tip indirectly led to a fire that killed 13 United States Marines and injured 68 at Combined Arms Training Center, Camp Fuji in the Shizuoka Prefecture of Japan.

Strong flow from across the equator was drawn into Roger's wind circulation, initially preventing significant development of the precursor disturbance to Tip.

Due to the large-scale circulation pattern of Tropical Storm Roger, Tip's precursor moved erratically and slowly executed a cyclonic loop to the southeast of Chuuk.

Reconnaissance aircraft provided the track of the surface circulation, since satellite imagery estimated the center was about 60 km (37 mi) from its true position.

Late on October 10, Tip attained wind speeds equal to Category 4 strength on the Saffir–Simpson Hurricane Scale (SSHS), and it became a super typhoon on the next day.

The central pressure dropped by 92 hPa (2.72 inHg) from October 9 to 11, during which the circulation pattern of Typhoon Tip expanded to a record diameter of 2,220 km (1,380 mi).

On October 17, Tip began to weaken steadily and decrease in size, recurving northeastward under the influence of a mid-level trough the next day.

[4] The typhoon produced heavy rainfall early in its lifetime while passing near Guam, including a total of 231 mm (9.1 in) at Andersen Air Force Base.

[1] Gusts of 125 km/h (80 mph) were measured during October 9 at the Naval Base Guam, as the center of the storm was positioned 70 km (43 mi) south of Agana.

[8] The outer rainbands of the large circulation of Tip produced moderate rainfall in the mountainous regions of the Philippine islands of Luzon and Visayas.

[9] Heavy rainfall from the typhoon breached a flood-retaining wall at Camp Fuji, a training facility for the United States Marine Corps near Yokosuka.

[9] The rainfall led to over 600 mudslides throughout the mountainous regions of Japan and flooded more than 22,000 homes; 42 people died throughout the country, with another 71 missing and 283 injured.

After a detailed study, three researchers determined that two typhoons, Angela in 1995 and Gay in 1992, registered higher Dvorak numbers than Tip, and concluded that one or both of the two may have therefore been more intense.
