Following incessant rains in Chennai and parts of Tamil Nadu over the last four days due to a depression over the Bay of Bengal which has been moving over northern Tamil Nadu, a red alert has been issued for districts in the state.

Many have been forced to leave their houses, and have also run out of food and water. The rains have also led to massive waterlogging, roads caving in and trees uprooted.

As per National Disaster Management Authority (NDMA), “Heavy to very heavy rainfall at a few places with extremely heavy falls at isolated places very likely over north coastal Tamil Nadu, north interior Tamil Nadu, south coastal Andhra Pradesh and Rayalaseema.”

As such, NDMA has been sharing dos and don’ts one should follow in case of lightning and flood on its Twitter page.
