BEIJING, June 19 (Xinhuanet) -- Shanghai sizzled for another day yesterday with the mercury reaching 36.6 degrees Celsius, making it the hottest day so far this year, but rain is expected to bring some relief from the scorching heat today.
The Shanghai Metrological Bureau issued the second yellow heat alert at 9:55am yesterday after the first one on Monday, warning that temperatures could soar to around 35-36 degrees.
A yellow heat alert is the lowest of a three-color warning system. Orange indicates temperatures above 37 degrees and red is for 40 degrees and over.
Avoid outdoor activities
The bureau said the temperature was rising quickly and advised residents to avoid prolonged stay outdoors. Those who worked outside should take necessary precautions, the bureau said.
At 2:30pm, the bureau's Xujiahui observatory recorded a temperature of 36.3 degrees. Observatories in districts like Jiading and Putuo and the Pudong New Area recorded a high of over 37 degrees.
People should avoid long-term exposure to the sun and drink more water, the bureau said.
The high humidity means people sweat more easily, it said.
Plum rain is expected to make a return today, with the wet weather likely to stay put for five days.
With showers and thunderstorms forecasted, the temperature is expected to drop to between 26 degrees and 31 degrees Celsius.
Tomorrow and Friday, it is expected to be overcast and rainy with a high of 29 degrees and a low of 23. The weekend should be overcast with heavy shower and thunderstorms predicted. The mercury will hit a low of 23 and a high of 30 degrees on Saturday and 24 and 28 on Sunday.
Plum rain season
Shanghai is still in the midst of the plum rain season, which is marked by weeks of rains and high humidity. The season began on June 7 this year, 10 days earlier than usual.
Wu Rui, chief service officer at the bureau, said Shanghai is experiencing a typical plum rain season this year - high temperature and high humidity. The season usually starts on June 17 on average and ends on July 10 in the city.
"It is impossible that the plum rain season will end earlier this year compared to the normal 20-plus days," Wu said.
Meanwhile, Typhoon Leepi has formed in the Philippines yesterday and moving toward Taiwan, the China Meteorological Administration said yesterday.
Local forecasters said it was still too early to determine its route and whether it would affect Shanghai.
The air quality reached the "lightly polluted" level yesterday because of the high humidity, the Shanghai Environmental Monitoring Center said. As the city swelters, ozone is becoming the chief air pollutant instead of particulates.
