The Observatory organized a seminar on lightning alert service on 25 March 2009 to publicize the newly-introduced lightning information service. There were over 80 participants from property management companies as well as operators of swimming pools and beaches under the Leisure and Cultural Services Department. The seminar introduced the location-specific lightning alert service and its application, basic knowledge of the science of lightning and protective measures against lightning.
A representative from one of the property management companies, Mr. Hung, shared his experience in using the lightning alert service. He commended that the service was very useful as it made the opening or suspension of swimming pools and outdoor recreational facilities more flexible. Also, Ms. Li, Assistant Leisure Manager of the Leisure and Cultural Services Department, said that the service had enabled swimming pool operators to have an overall picture of how far away the thunderstorms were, thus contributing towards the safe operation of swimming pools.
