BEIJING (XINHUA) - China's national observatory continued to issue an orange alert for high temperatures on Thursday (July 28), as intense heatwaves linger in many regions of the country.

During daylight hours on Thursday, vast swathes of China's southern regions and some parts of Xinjiang and Inner Mongolia are expected to experience temperatures of over 35 deg C, said the National Meteorological Centre.

Temperatures in some regions of Zhejiang, Jiangxi and Xinjiang may surpass 40 deg C, according to the forecast.

The meteorological centre has advised the public to avoid outdoor activities during high-temperature periods and suggested that workers exposed to high temperatures shorten continuous working hours.

Local governments have been advised to take appropriate heat control measures and necessary protective steps against fires triggered by electrical overloads.

China has a four-tier colour-coded weather warning system.

Red represents the most severe warning, followed by orange, yellow and blue.
