HARBIN, July 25 (Xinhua) -- Northeast China's Heilongjiang Province activated a red alert for rainstorms at 8 a.m. on Friday.

According to the Heilongjiang Meteorological Observatory, it is expected that some southern townships of the Mongolian Autonomous County of Dorbod, Heilongjiang, could receive accumulated precipitation of up to 100 mm within the space of just three hours.

At 5:50 a.m. on Friday, the provincial meteorological observatory issued a high-impact weather forecast, predicting short-term heavy rainfall in the provincial capital Harbin's main urban area and in cities such as Zhaodong, Wuchang and Shangzhi, within six hours after the issuing of the forecast.

Thunderstorms and strong winds are expected in some parts of the province, with gusts reaching a maximum force of level 7 to 8.

Local weather authorities advised all relevant departments to implement emergency flood prevention and disaster response measures -- including timely evacuation of personnel from high-risk areas. Comprehensive defenses against urban waterlogging, river floods and mountain torrents should be reinforced, with intensified inspections and reinforcement of bridges, culverts, roadbeds, embankments and reservoirs.

China has a four-tier weather warning system -- with red representing the most severe warning, followed by orange, yellow and blue. ■
