The No 1 signal was hoisted in Hong Kong yesterday as Typhoon Fanapi headed for eastern Guangdong and Fujian this morning, after earlier battering Taiwan as a severe typhoon. It is predicted to move inland as a severe tropical storm, bringing squalls and heavy rain to Hong Kong later today and tomorrow. Several flights from Taiwan to Hong Kong were affected. Six Dragonair flights to Hong Kong were delayed and two cancelled. At 1am, Typhoon Fanapi was about 520 kilometres east-northeast of Hong Kong and forecast to move west at about 20km/h towards the mainland. The Observatory issued the No 1 signal at 4.30pm, warning that the storm could still affect the MidAutumn Festival on Wednesday. As Fanapi moved west through Guangdong, winds were expected to increase, said Mok Hing-yim, a senior scientific officer at the Observatory. Thunderstorms were expected in Hong Kong for the next few days and it was unlikely the sky would be clear for the night of the Mid-Autumn Festival. Meanwhile, the very-hot-weather warning, which had remained in force for 30 hours, was cancelled at 7.30pm yesterday. Fourteen temporary night shelters were opened by the Home Affairs Department for people seeking to escape the heat. By 5pm yesterday, about 1,300 elderly people had sought help via a portable emergency device. They contacted a call centre by pressing a button on the device. Forty-five callers were taken to hospital, with most suffering from heat-induced aches and pains and dizziness, the Senior Citizen Home Safety Association said.
