Northeast monsoon likely to begin over southern India within days
The Northeast monsoon is expected to begin over the south peninsula within two to three days, as the Southwest monsoon withdraws from the rest of India.
Tamil Nadu, which relies on the Northeast monsoon for a major share of its annual rainfall, is expected to see rain increase from Wednesday, October 14.
Rain is forecast across many parts of the State, with some districts likely to get heavy rain from October 15 and wet conditions possibly lasting until October 18.
The monsoon’s arrival depends on how a weather system over the Southeast Bay of Bengal develops and moves.
More rain may also bring some relief from above-average temperatures after October 15.
Traders at Chennai’s Koyambedu wholesale market hope improved rainfall will increase vegetable supplies and help prices ease within two weeks.
They say low yields in Andhra Pradesh and Karnataka have contributed to shortages and higher prices.
The Northeast monsoon is likely to begin over the south peninsula within the next two to three days, the Regional Meteorological Centre said.
Rainfall in Tamil Nadu is expected to increase from Wednesday, October 14, with fairly widespread rain from Thursday.
Some districts could see heavy rain from October 15, and rain in parts of the State may continue until October 18.
The monsoon’s onset depends on the development and path of a weather system that could form a low-pressure area over the Southeast Bay of Bengal.
