[2] The Japanese Meteorological Agency (JMA) designated the system as a tropical depression also at that time, with the pressure reading at 1,000 hectopascals (30 inHg).

[3][nb 1] At 12:00 UTC, the JTWC assessed the system had reached tropical storm strength 330 kilometres (205 mi) west of Iwo Jima, with winds of 75 km/h (45 mph).

According to the JTWC, Wendy reached peak strength offshore Shikoku, with winds of 140 km/h (85 mph) on August 12 at 00:00 UTC,[5] but the lowest pressure, 990 hPa (29 inHg), was recorded six hours later by the JMA.

Wendy soon made another landfall over southern Honshu later that day, remaining on land for ten hours, and weakening to 75 km/h (45 mph).

[3] The storm sped up and made its final landfall over northern Honshu on August 13 at 03:00 UTC, with winds of 80 km/h (50 mph) and pressure of 1,004 hPa (29.6 inHg).

[2] The JMA declared the storm extratropical at the same time, and the agency continued to track the cyclone until it reached near the International Date Line at 18:00 UTC on August 15.
