Heavy rains to lash Chennai, districts for 4 more days

Heavy rain lashed many parts of Tamil Nadu, including Chennai, once again even as the weather office forecast more rains. Another trough developed near South West of Andaman which started to move westwards. Located at south west of Bay of Bengal, the low pressure zone is expected to move further slowly. “Since the trough of low pressure will be moving towards the western parts of the state, Chennai and the coastal districts can expect heavy downpour,” said the Met Department director SR Ramanan. 

A few low-lying areas quickly got inundated and traffic in various parts of the city slowed down post the showers in the first half of the day. Moderate to rather heavy rain would occur at many places over all the districts of coastal Tamil Nadu and Puduchery. Rain also continued to lash Tiruchirappalli, Nagapattinam, Thanjavur and Tiruvarur, among others. The average annual rain fall for the state is 44 cms. So far, TN has already received 52 cms of rain. The state’s North-east monsoon period lasts till Dec 31. Pedestrians pull out their umbrellas as rains lash the city on Monday
