Forecast calls for warmer weather

THE weather is expected to heat up with the temperature rising above 30 degrees Celsius by midweek, meteorologists said.

Today will be mostly cloudy with a high of 29 degrees and a low of 19 degrees, according to the Shanghai Meteorological Bureau.

Tomorrow should remain cloudy with the mercury ranging between 20 and 29 degrees.

The bureau also said that Wednesday will be mainly sunny with a forecast high of at least 30 degrees.

Meanwhile, air quality declined yesterday with the end of the rain, according to the Shanghai Environmental Monitoring Center.

The air quality index reached 113, or "lightly polluted," at 3pm yesterday with PM2.5 the chief pollutant.

"The field of pressure is weak these days and the wind is not strong," said Fu Yi, a chief service officer of the weather bureau.

Fu said the smog may improve today as the day progresses.

Shanghai will start issuing PM2.5 forecasts later this year, initially offering 24-hour predictions before going to 48-hour forecasts, according to the Shanghai Environmental Protection Bureau.

PM2.5 refers to airborne particles smaller than 2.5 micrometers in diameter. They are the main cause of urban smog and can harm human health.

Only 59 days, or 65 percent, in the first quarter were not polluted while there were 10 days with heavy pollution, according to the bureau.
