[2] After a month of inactivity, a tropical storm formed several thousands of miles south-west of the southern tip of Baja California.

[6] The storm was potentially a continuation of a previously unnamed tropical cyclone that was monitored west of the Baja California Peninsula from July 24-27, but was never confirmed due to a lack of ship reports.

[6][8] Intensity leveled off afterwards as Dot tracked westward before making a curve towards the northwest on August 5, after which the hurricane weakened at a faster clip.

[7] Dot made landfall the next day on Kauai as a minimal hurricane before dissipating west of the Hawaiian Islands on August 8.

[8] Dot produced heavy rainfall and gusty winds as it passed south of the Big Island, Lanai, Maui, Molokai, and Oahu, resulting in minor damage.

[10] Extensive damage occurred on Kauai as Dot made landfall, producing wind gusts as high as 103 mph (166 km/h) and toppling trees and power lines.

[7] Widespread power outages affected the island,[11] causing telecommunications and water systems to fail.

[9] Overall, damage from Dot across Hawaii totaled US$6 million,[7][9] and a disaster area declaration and state of emergency took effect for the archipelago after the hurricane's passage.

The Japan Meteorological Agency's best track at this time Patsy crossed the dateline, at Category 4 strength.

A second trough then formed, dominated the first, and recurved Patsy northeast, recrossing the dateline, at Category 3 intensity.

[18] The National Hurricane Center's "best track" data set has Patsy exclusively east of the dateline from detection to dissipation.

[19] The Japan Meteorological Agency's "best track" does not give wind speeds, only indicating that Patsy was a typhoon.

[20] The Joint Typhoon Warning Center's report disagrees on location but also has Patsy's maximum windspeed east of the dateline.

It made landfall as a Category 4 on October 27 and killed at least 1800 people, making it the deadliest pacific hurricane on record.
