A No 3 strong wind signal was hoisted at 9.15pm yesterday - the first of the year - after a day of torrential rain that caused widespread flooding and brought reports of landslips across the SAR. Meteorologists warned there would be more rain over the next two or three days as a tropical depression first detected 35km south of Lantau moved over the SAR overnight. Heavy rain and thunderstorms are forecast today and scattered showers tomorrow. By 6.30pm, 13 cases of flooding were reported across the SAR - seven in west and south Kowloon and the rest in the New Territories. Nine landslips, including five in Tseung Kwan O and two in Mid-Levels, were also reported. The thunderstorm warning was issued for about 12 hours late on Saturday night while the amber rainstorm signal was issued for nearly five hours yesterday morning. A landslip warning has been in force since 7am yesterday.
