As the developing depression was crossing the Philippines, it brought heavy showers of up to 400 mm (16 inches), which caused some flooding in the Cagayan Valley Eighteen people were killed in landslides in northern Luzon. As Typhoon York approached and landed on Hong Kong's Lantau Island, the Hong Kong Observatory (HKO) raised the No. 10 warning for the first time since 1983 and maintained it for 11 hours, the longest hoisting period on record. The peak sustained winds of 150 km/h (95 mph) were recorded on Waglan Island and the peak gusts of 234 km/h (146 mph) were the highest on record there. A total of 300 mm (12 inches) of rain fell on the territory as York passed directly over it and the resulting floods had a severe effect on agriculture throughout Hong Kong. Two people died in the storm and over 500 were injured, 11 seriously. Some 18,000 homes lost power in the wake of the storm and 4,000 trees were uprooted. Damage from York in Hong Kong exceeded $10 million (USD), and economic losses from the storm reached several billion Hong Kong dollars (HKD). Transport in the territory was severely disrupted, with 470 flights cancelled and 80,000 passengers affected.
