Bengaluru was pounded by heavy showers on Sunday, leaving a trail of destruction, affecting normal life. Thunderstorm activity was accompanied by gusty winds and lightning strikes. A large number of trees were uprooted, snapping transmission lines. Power outages affected some pockets for long durations. Commuters were troubled because of the flooding of roads and the arterial roads getting choked. Small mercy, being Sunday, traffic was not at peak and therefore, disruptions were not large.

The GKVK complex at Yelahanka, a suburb of Bengaluru, had moderate spell of 44.2mm. The spatial distribution was more of a pre-monsoon type and the least of the monsoonal pattern. HAL observatory did not record any rainfall at all.
