As flood waters caused by a week-long torrential downpour have receded in Colombo as well as Kelaniya and Kaduwela areas of Sri Lanka, relief measures have been launched. However, heavy rains continue to lash other regions in what is being called the heaviest downpour in 25 years. Already two major landslides have been triggered, burying victims and displaced numerous others.

Despite clearer skies in some regions, the government is now concerned about the outbreak of disease in the aftermath of the disaster. "There is a real danger of diarrhoea and skin diseases spreading among the flood victims," Colombo Municipal Council medical chief Ruwan Wijayamuni said.
