Hong Kong, Aug 2 (NationPress) - On Saturday, the Hong Kong Observatory once again raised the black rainstorm warning signal, marking the second occurrence this week.
This alert signifies that heavy rainfall is either currently occurring or anticipated, with amounts exceeding 70 millimeters per hour, and is expected to persist.
The Emergency Coordination Centre of the Home Affairs Department of the Hong Kong Special Administrative Region (HKSAR) government is now operational, providing temporary shelters for those in need.
As a result of the rainstorm, numerous public services and activities within the HKSAR have been suspended, according to reports from Xinhua.
Public general outpatient clinics and specialist outpatient clinics are closed. All schools have called off classes for the afternoon. In addition, Hong Kong Wetland Park has closed its doors, and individuals are advised to steer clear of country parks.
Previously, on July 29, the Hong Kong Observatory had issued its initial black rainstorm warning of the year.
This warning indicates that extensive regions of Hong Kong have reported or are forecasted to experience rainfall exceeding 70 mm per hour, with the heavy rain likely to continue.
According to the Observatory, vigorous thunderstorm activity linked to a broad low-pressure trough has led to notably intense rainfall on Lamma Island, where hourly precipitation has surpassed 100 mm.
Following the warning, the HKSAR government activated its Emergency Coordination Centre under the Home Affairs Department and opened temporary shelters for those needing emergency accommodation. The Education Bureau has advised schools to adopt contingency measures to safeguard students.
In a related event, at least 30 fatalities occurred due to heavy rainstorms in Beijing.
The casualties were reported in the northern mountainous districts of Beijing, with 28 in Miyun and two in Yanqing, as stated by the Beijing municipal flood control headquarters.
A total of 80,332 individuals were relocated across the city, with the highest rainfall recorded in Miyun, reaching 543.4 mm, according to local authorities.
The rainstorms have damaged 31 road sections and disrupted power supply in 136 villages.
Recently, extreme and severe convective weather, driven by warm, moist air from the edge of the subtropical high, has impacted Miyun and other regions in Beijing.
