New Delhi, Aug 11 - This monsoon's second heavy rainfall in the capital flooded several roads and low-lying areas Tuesday after drains got choked, causing massive traffic pile ups all across the city.

The otherwise welcome afternoon showers brought some respite to people reeling under hot and humid weather. The city received 43.8 mm of rainfall in an hour, bringing down the day temperature by several degrees.

However, civic facilities simply crumbled in many areas, particularly in south Delhi and the more populous east Delhi.

Delhi Mayor Kanwar Sain admitted to IANS that there were problems.

'We have been cleaning the drains and desilting storm water channels. Still there are reports of water logging especially in low lying areas. We have deployed teams in places were there are problems.'

Thousands of people were stuck in serpentine traffic jams as traffic signals snapped due to heavy rains.
