The government is advising communities living downstream of Manyera dam in Vumba that the dam wall has weakened.
This has been caused by Tropical Cyclone Idai-induced rains — which continue to pound the vicinity, filling up dams, affecting their walls.
Vumba District has seen massive landslides, a development likely to prevent authorities from fully appreciating the threat that exists.
Roads have collapsed in landslides in the sparsely-populated Chimanimani and Rusitu Valley.
