But rains below normal in river catchment areas
The South West Monsoon has shown signs of regaining traction with intermittent rains in Mysuru, Mandya, Chamarajanagar and Kodagu since the last 48 hours.
The rainfall has been uniform and widespread with overcast sky throughout the 48-hour period. But concerns remain over low storage levels in the major reservoirs of the region.
According to the Karnataka State Natural Disaster Monitoring Centre (KSNDMC), Kodagu has received 48.01 mm of rainfall during the 24 hours ending 8.30 a.m. on Thursday. This is against a normal of 26 mm for the same period. Mysuru has received 7.7 mm against a normal of 2.9 mm while Mandya received 5.4 mm against a normal of 2.9 mm during the same period.

The rainfall in Kodagu district is 35 per cent below normal. The district has received only 625.5 mm against a normal of 963.6 mm so far. The deficit is 52 per cent. Against the normal of 430 mm, Kodagu has received only 204.3 mm so far during the month.

Between June 1 and July 15, the district received 405.6 mm against a normal of 598.4 mm, the deficit being 32 per cent.

Kote taluk was at the rate of 11,628 cusecs on Thursday morning and the water level was 2278.02 ft. against the FRL of 2284 ft.
