Heavy, night-long, torrential rains brought Bengaluru to its knees on Monday as several areas were inaccessible. Water-logging on roads including arterial ones hit traffic flow while boats and tractors were pressed into service in certain parts.

Water-logging on Sarjapur Road among others were to such extent that tractors and boats were used to ferry students and office goers in the morning.

Several lakes in the city overflowed and drains flooded. Many low-lying areas were worst hit, with water entering houses and disrupting daily activities.
