CHENNAI: The Regional Meteorological Centre (RMC) has concluded the northeast monsoon season in Tamil Nadu and Puducherry with an overall ‘Normal’ status for the period from October 1 to December 31.

The region received 42 cm of rainfall against the seasonal average of 44 cm, reflecting a marginal deficit of 3%, which falls within the near-normal range set by the India Meteorological Department.

While the cumulative regional figures indicate normal performance, district-wise data shows uneven distribution.

However, 10 districts in north-central and interior belts faced a deficit, with seasonal shortfall ranging from 20-59%.

In contrast, southern districts experienced higher rainfall. Tirunelveli topped the chart with a ‘large excess’, registering a 95% surplus. Tenkasi, Virudhunagar and Ranipet also recorded excess rainfall.
