Trees came crashing down, distrupting traffic, yesterday as torrential rain lashed the territory in a series of violent downpours. The Hong Kong Observatory issued the amber rainstorm warning at 2.20am and again at 6.55am. A thunderstorm warning was also issued in the early hours of the morning. The Observatory recorded a total of 38.2mm of rain at its headquarters in Tsim Sha Tsui by midday. The heaviest downpours were in Sha Tin and Tsuen Wan, with both districts recording at least 100mm by noon, and about half of that between 6am and 8am, bringing chaos to rush-hour traffic. Trees fell in Sha Tin, Tsuen Wan, Kwun Tong and Tsim Sha Tsui during the downpours. Two that toppled disrupted traffic. A 12-metre tree fell on the Shing Mun Tunnel Highway near Tai Wai in Sha Tin, blocking traffic heading towards Sha Tin at 6.30am. It took firemen about 30 minutes to remove the tree and re-open the road. Another tree toppled on Cheung Pei Shan Road, Tsuen Wan, at 7.25am. The slow lane was cordoned off for about half an hour. No injuries were reported. Yesterday's downpours came after Hong Kong sweltered through the first half of the month with the mercury topping 30 degrees Celsius each day - one of the hottest stretches recorded in recent years. Weathermen last night predicted more heavy downpours today and squally thunderstorms until Saturday. Sunny weather is forecast to return early next week.
