At the request of the Secretary-General of World Meteorological Organization, Mr C.Y. Lam, Director of the Hong Kong Observatory, paid a 1-week mission visit to Department of Meteorology, Sri Lanka, at the end of January 2006.

He provided advice to the department on the preparation of its master plan for development, which aims at upgrading the department to cope with future disasters. The need for an effective early warning system has been highlighted by the damage caused by the tsunami which hit Sri Lanka on 26 December 2004.
