Northeast Monsoon is the main season for rain activities in Tamil Nadu. The season contributes around 48% annual rainfall for the state with a seasonal normal of 438.2 mm. Out of the three months of Northeast Monsoon, November is the rainiest month with an average 170 mm rain. Also, the state of Tamil Nadu is the one contender for the maximum amount of rains in November.
However, the state has shown a large variation from the pattern this time. While October turned out 27% rain surplus, November performed poorly sliding into a rain deficiency of 9%.
Moderate rains have been recorded across the state in the last 24 hours. The city of Chennai also received light rains yesterday. We expect this Northeast Monsoon activity to continue for the next few days as well. It will take another subsequent 48 hours for the rains to reduce.
Rains will pick up again on November 26. Moreover, the month-end awaits a rainy end with a forecast of moderate to heavy rains from November 26 to 30, especially along the coastline.
These rains will be able to lock down the deficiency figures for now. However, these rains possibly might not be able to make up for the rain deficiency.
