Hundreds treated for heatstroke, and weather bureau warns of more to come A subtropical high-pressure system is wreaking havoc on the mainland, with the lower reaches of the Yangtze river suffering under scorching heat while Beijing swelters in unusually high humidity. Temperatures soared to 40 degrees Celsius over most of Zhejiang province at the weekend, a spokeswoman for the provincial meteorological department said. She said record temperatures had been experienced in 20 counties across the province in the past week. Hundreds of people have suffered heatstroke in Lishui city, where a province-high 42.5 degrees was recorded last Friday. Lou Tianzheng, a doctor at the Lishui People's Hospital, said staff had admitted more than 100 heatstroke patients yesterday alone. A spokeswoman for the Lishui weather station said the heat would continue for at least the next few days. Two other cities in Zhejiang province, Yiwu and Wuyi, experienced temperatures of 40 degrees yesterday. Shanghai reached 39.6 degrees and Wuhan 40 degrees, the highest ever for both cities. Unpredictable weather has created a number of difficulties this year. Floods are still threatening provinces along the Huai river; rainstorms and landslides have killed dozens of people in Hubei province and Sichuan; a typhoon blasted Guangdong and Hunan province is suffering from a drought. Beijing, usually dry and hot, is meanwhile experiencing the kind of moist weather typical of southern China. The average humidity has been above 80 per cent for the past week and shot up to 93 per cent on Thursday, according to the Beijing Evening News. Mainland newspapers yesterday described Beijing's weather as being 'like a sauna'. In Hunan province in central China, about 1.14 million people lack water in 64 districts due to inadequate rainfall and a heat wave which has scorched the region since the end of June, state media reported. The province's poorly maintained irrigation systems were battered further by heavy rains that soaked the region in the spring, the China News Agency reported. More than 2,000 streams and rivers have since dried up and about 860,000 hectares of arable land have been rendered useless by the drought, which is also affecting Jiangxi and Fujian provinces.
