Chennai and the region around has automotive plants of manufacturers like Renault-Nissan, Daimler India Commercial Vehicles, BMW, Yamaha, Ford, Ashok Leyland, Royal Enfield and others. The heavy downpour in the region in early November affected the operations of these OEMs. Operations of a good deal of automotive suppliers in the region were also affected because of the heavy rains. With many people working in these companies unable to reach their place of work due to flooding, production at the plants of OEMs as well as the suppliers was affected. The extent of impact due to the unexpected torrential downpour may take time to be ascertained, and is expected to be felt for some time after the return to normalcy. The only tow OEMs that did not seem to be affected are Mahindra and Hyundai. Both have their plants om the Bangalore highway. The impact of the rain there was not as bad as some of the other areas in the Chennai region. Such was the effect of the torrential downpour and the subsequent flooding that IT companies had to declare a holiday. Schools and colleges were also closed and several examinations had to be rescheduled. While 71 people are known to have been killed, the state government has had to announce a relief of Rs. 500 crore. Rail and air services were severely affected too.
