Poor rains in parts of state for 2 more weeks

Sub-optimal monsoon conditions recorded in South Interior Karnataka are expected to continue as India Meteorological Department has forecast below normal rainfall in the region for the next two weeks.

Data shows that due to delay in monsoon onset, the State has recorded a deficit of 28% in June. A deficiency of 20% of more in June has been recorded only seven times since 1971 and thrice since 2010, including this year.

Moreover, the four reservoirs in Cauvery basin which receive an average inflow of 31.5 tmc ft in the month of June have received only three tmc ft this year.

Speaking to DH, G S Sreenivas Reddy, Director, Karnataka Natural Disaster Monitoring Cell, said that forecast was not encouraging for the next couple of weeks, especially in the South Interior Karnataka. "There was good rainfall in North Interior Karnataka due to a low-pressure region in Bay of Bengal. However, the intensity of the rainfall in that region too is expected to reduce," he said.

Rainfall has also decreased in Coastal and Malnad regions. "Though forecasts indicate widespread rainfall in these parts, intensity will be less," he said.
