Hongkongers hit beaches around the city in droves yesterday as the temperature climbed to 33.1 degrees Celsius, though the Observatory warned it may go even higher today and hit 34 degrees, which would make it the hottest day so far this year. The Observatory has advised people to stay indoors, take it easy and have plenty of cold drinks. Yesterday's heat overcame at least one person, a 17-year-old who was taken to North District Hospital with heat stroke in the morning and discharged in the afternoon after treatment. The sweltering weather is the result of a huge typhoon, Haitang, which is nearing Taiwan and which has led to the cancellation of flights in the area. Forecasters said the weather would remain fine and very hot, with temperatures expected to range from 29 to 34 degrees. Some haze with isolated showers and thunderstorms were also predicted. But the weather was expected to cool off a little after tomorrow, with temperatures falling to between 26 and 32 degrees and showers expected.
