 The monsoon trough spawned a tropical depression near Kwajalein on July 22. It headed northwestward, becoming a tropical storm on July 23 and a typhoon on July 24. A shortwave trough forced Bess southwestward where it remained a 90 knots (170 km / h) typhoon. It looped and stalled until another shortwave trough brought the typhoon to the northwest. Bess rapidly intensified to a 140 knots (260 km / h) super typhoon, and weakened steadily as it turned more northward. Bess crossed the Japanese coast on August 1 as a minimal typhoon, and was absorbed by a low pressure center in the Sea of Japan on August 2. Bess caused torrential mudslides in Japan, causing extensive damage and 59 casualties. The name Bess was retired after this season.
