Heavy rains in various parts of Chennai, more predicted

Residents of the city woke up to an overcast sky and rain today. Many parts of Chennai received moderate to heavy rains.

The same weather pattern may continue for the next few days over north Tamil Nadu, according to the Meteorological Department.

S Balachandran, Deputy Director General of Meteorology, Chennai, said a low pressure area was expected to form over the east-central Bay of Bengal and aid in rainfall over parts of the State, particularly the coastal region.

Rainfall in several areas brought down the day temperature by several notches in the city. Weathermen have forecast more thunderstorms in the city if the system brewing over Bay of Bengal moves towards Andhra Pradesh coast.

Weather enthusiasts said while a favourable wind pattern could persist at least for the next four days that could bring rain to the city and the neighbouring districts, there seem to be no indication for the entry of easterlies, one of the first signs for the onset of northeast monsoon, till October 26.

The Indian Meteorological Department has predicted heavy rainfall in Chennai and other districts of Tamil Nadu from October 19-21 due to the formation of a low-pressure area over the Bay of Bengal.

Chennai and surrounding districts could witness light to moderate rains over the next four days after a hot week. This is the direct result of a low-pressure area which is likely to form over the East-Central Bay of Bengal and adjoining Andaman sea on October 19. It will become more marked during the subsequent 24 hours.
