* Due to malfunction of wind station on 25 April 2012, wind speed data was obtained from the HKO’s Automatic Weather Station in Siu Ho Wan. However, as informed by the Hong Kong Observatory, the relevant wind data in April 2012 is not yet available on the report issuing date (14 May 2012) due to their internal dataset quality control. Relevant wind data will be provided in next monthly report.
