Update | Wet weekend in store as thunderstorm, landslide warnings remain in force

Foul weather continued to plague Hong Kong on Friday evening after the city was last night battered by the second black rainstorm of the year and gusts of wind up to 100km/h.

Heavy showers were accompanied by rumbles of thunder, while forecasters said there was more to come over the weekend.

The amber rainstorm warning was raised at 8.50pm on Friday, the second time in 24 hours after the city was lashed by rain on Thursday, with flash floods bringing traffic to a standstill in Causeway Bay and other areas. 

The warning forecast heavy rain exceeding 30 millimetres in an hour, but was taken down by 10.20pm on Friday night. Landslip and thunderstorm warnings remain in force as further bad weather is expected.

Hong Kong Observatory on Friday afternoon warned of the risk of landslips caused by the continuing downpours, telling motorists to keep off roads where landslip signs are present and warning people to stay away from steep slopes or retaining walls.

An Observatory forecast issued at 12.45pm said: "A trough of low pressure is bringing rain and thunderstorms to southern China and the northern part of the South China Sea. Locally, more than 30 millimetres of rainfall were recorded over Clear Water Bay, the southern part of Hong Kong Island and the southern part of Lantau Island in the past few hours."
