Super Typhoon Hope, known in the Philippines as Typhoon Ising, was a powerful Category 4 typhoon that killed over 100 people when it struck Hong Kong in 1979. The fifth typhoon and first super typhoon of the 1979 Pacific typhoon season, it formed as a tropical depression southeast of Guam on July 24. It headed to the west-northwest, but upper-level shear from the TUTT caused the depression to dissipate on the 27th. It turned northward then westward, where it regenerated on the 28th. Intensification became more steady, with the depression reaching storm strength on the 28th and typhoon strength on the 29th. On the 31st, Hope reached a peak of 150 mph winds, but land interaction with Taiwan to the north weakened the storm.
