Giant hailstones pounded parts of Hong Kong tonight as thunderstorms echoed around the city and the Black Rainstorm warning was issued for just the second time in two years.
Hailstones the size of golfballs were reported in Tsuen Wan as festivities to mark the end of the Hong Kong Rugby Sevens were washed out.
Thunderstorms were accompanied by near constant flashes of lightning as the Observatory stated that more than 70 millimetres of rain had fallen in some parts in less than an hour.

A stack of more than 20 cargo containers collapsed at the container terminal in Kwai Chung.
Flooding was reported in areas including Cheung Chau, Tuen Mun, Mong Kok and Sheung Shui, while a landslide was reported in Sai Kung.
MTR stations at Kowloon Tong and Wong Tai Sin also reported flooding.
A stack of more than 20 cargo containers collapsed at the container terminal in Kwai Chung.“Heavy rain is affecting the northern part of the New Territories, especially in Yuen Long, Pat Heung and Kam Tim areas. More than 70 millimetres have been recorded in the past one hour,” the Observatory said.
“Hail was reported at Wong Tai Sin at around 8.30pm,” the Observatory added, saying that gusts reaching 100kmh had been reported.
The last Black Rainstorm warning was issued in May 2013.

Black clouds darkened the stadium before lunchtime Saturday, forcing organisers to switch on floodlights and leading to sodden conditions.
The Observatory said earlier this month that up to seven typhoons were expected to hit the city this year.
It added that as climate change progresses, Hong Kong would see more extreme weather in the future.
Heavy Rain and hail on March 30, 2014
The warm and humid airstream associated with a trough of low pressure over the coast of Guangdong converged with a cooler easterly airstream near the Pearl River Estuary last evening (30 March 2014), bringing squally thunderstorms, hail, heavy rain and high winds to Hong Kong. The Hong Kong Observatory issued the Red and Black Rainstorm Warning Signals at 8:15 pm and 8:40 pm respectively, which were the earliest Red and Black Rainstorm Warning Signals in a year since the Rainstorm Warning System commenced in 1992.
Between 9 pm and 10 pm yesterday (30 March 2014), 56 millimetres of rainfall were recorded at the Hong Kong Observatory. This was the highest hourly rainfall on record (Note 1) for the Hong Kong Observatory for March. Over a space of 3 to 4 hours, more than 100 millimetres of rainfall were recorded over widespread areas in Kowloon and the New Territories. Rainfall even exceeded 150 millimetres over Yuen Long, Tuen Mun, Tsuen Wan and Sha Tin (Figure 1). Based on the past record for March, more than 100 millimetres of rainfall registered in a day over the Hong Kong Observatory occurred only 4 times since 1884 (Table 1). For the whole year, daily rainfall exceeding 100 millimetres was recorded about four days in a year on average (Note 2).
There were also hail reports in many parts of the territory (Figure 2). Most of them reported hail with a size of about 20 to 30 millimetres. According to past records, hailstones with size of up to about 100 millimetres were reported in Hong Kong on 19 March 1981.
The aforementioned trough of low pressure over the coast of Guangdong is expected to linger around for a couple of days and the weather will remain unsettled in the region.
