Most parts of T.N. likely to receive below normal rainfall in September: IMD
The India Meteorological Department predicts below-normal rainfall for most of Tamil Nadu in September due to strong El Nino conditions. While some northern regions may see normal precipitation, the overall deficit poses risks to agriculture and water resources.
Why it matters
Accurate weather forecasting is essential for agricultural planning and water management in regions vulnerable to monsoon variability.
Most parts of Tamil Nadu are likely to receive below normal monsoon rainfall in September except for pockets in the northern districts, according to India Meteorological Department (IMD).
In its weather outlook for September, the IMD has said that the monthly rainfall over the country was likely to be below normal, with expected rainfall at 91% of the long period average. Some north and interior parts of Tamil Nadu may receive normal to above normal rainfall in September.
It has also warned that below normal rainfall could adversely affect water resources and agriculture, besides increasing risk of heat stress across several regions of the country.
Tamil Nadu has so far recorded an overall rainfall of 16.3 cm, which is 22% below normal during this Southwest monsoon since June 1. Many districts, including Ariyalur, Nagapattinam, and Thoothukudi recorded significant rainfall deficits, according to the Regional Meteorological Centre (RMC).
