These areas had already suffered heavily during the earlier spells of rains.<br/><br/>A large part of the road near Madhya Kailash temple in the heart of the city in an area that connects the IT corridor has caved in resulting in a huge crater and disrupting<br/>traffic.<br/><br/> Even in hitherto unaffected areas, people have complained that water entered their homes and roads flooded with surging waters. Several areas in Chennai went without power as supply<br/>was cut as a safety precaution.<br/><br/>DG MeT Department Laxman Singh Rathore said, extremely heavy rainfall has been occurring for sometime and today Tamil Nadu has witnessed 35 cm of rainfall that has created havoc. He, however, said that intensity of rain will decrease in the next 48 hours and further by 72 hours but it is likely to continue for five-seven days.
