The rains which prevailed during the past few days will continue while minor flood threat in the Colombo and Gampaha districts had lessened somewhat, the Disaster Management Centre (DMC) Deputy Director Pradeep Kodippili said.
He said according to the Irrigation Department, that as of last afternoon the water levels at Nagalagama Street had reached alert level.
He said the residents living downstream along the banks of the Kelani River and the Attanagalu Oya should be vigilant of rising water levels.
Dunamale in the Attanagalu Oya had reached minor flood level while water levels at several places had increased in the Kelani River downstream from Hanwella.
Mr. Kodippili said the spill gates of several reservoirs including Rajanganaya, Angamuwa and Thabbowa and Deduru Oya had remained open due to the rains.
He said people should be vigilant for possible landslide threats in the Kalutara District, Walallawita, Agalawatta, Ingiriya, Bulathsinhala and Palindanuwara DS division and surrounding areas.
