This system formed in the near equatorial trough southeast of Ponape a few days after Thad on October 20. The system moved northwest to just north of Ponape as it slowly developed. The disturbance strengthened into a tropical depression by October 22 and a tropical storm October 23 despite some northwesterly shear from Thad. As a minimal typhoon, Vanessa moved about 165 kilometres (103 mi) south of Guam, where winds gusted to 59 knots (109 km/h) on Nimitz Hill. Damage on the island totaled US$1.7 million (1984 dollars), mainly to the banana crop. Moving west-northwest, Vanessa continued to strengthen, becoming a super typhoon. Super Typhoon Vanessa was the strongest typhoon of the season, reaching maximum sustained wind speeds of 190 miles per hour (310 km/h) over the open waters of the West Pacific. At its peak, it had a pressure of 880 mb, only 10 millibars higher than the record-setting Typhoon Tip of 1979. Its central pressure fell 100 mb in 48 hours. The intense cyclone recurved on October 27 and October 28 as a cold front approached from the northwest. Vanessa slowly merged with the frontal boundary, becoming a storm-force extratropical cyclone late on October 30.
Impact
Though the storm did not directly impact the Philippines, its outer bands triggered flooding that killed 63 people.
