Pollution set to ease today, but keep your face mask handy

By Ke Jiayun | May 27, 2014, Tuesday | Print Edition

THE early summer heat wave worsened the city’s air quality to a heavily polluted level yesterday morning, and masks may still be needed today, forecasters said.

An increase in winds may moderate pollution concentrations today, dropping them to light or moderate readings. The air quality index yesterday peaked at 225 at 9am, with the main smog pollutant PM2.5 particles reaching over 170 micrograms per cubic meter.

People with weak respiratory systems are advised to stay indoors today.

The temperature is forecast to reach 34 degrees Celsius today. Yesterday the mercury topped 30 degrees for the first time this year, climbing to 31 degrees.

The hot weather this week will bring some sunshine. Tomorrow’s high is forecast to be 34 degrees, with the mercury easing to 32 degrees under cloudy skies on Thursday.

On Friday, cooler weather is set to return, with scattered showers expected on the weekend. The top temperatures for Friday and Saturday are forecast at 27 and 29 degrees.

Meanwhile, the Shanghai Meteorological Bureau said this year’s flood season will see less rain than usual, but more convective storms and an equal number of hot weather days (over 35 degrees) and typhoons.

The government is already preparing flood-prevention measures designed to keep water and electricity supplies intact during the storms and ensure up-to-date weather alerts.
