Monsoon rains in South India have disappointed so far. Looking at the rainfall data available with Skymet, the South Peninsula subdivision is the most deficient pocket in the country. The shortfall in the region currently stands at 30%.
Among the 10 meteorological divisions in South Peninsula, Andaman and Nicobar Islands and North Interior Karnataka are surplus by30% and 5%, respectively. South interior Karnataka is deficient by 17% which is considered normal in meteorological terms (+-19 is considered normal). Rest all divisions are observing a shortfall.
If we look back, the onset of Monsoon itself was delayed in Kerala by almost a week. Usually, by June 10 most of the South Peninsula is covered but rainfall in the entire region remained subdued until June 19. Coastal Karnataka, South Interior Karnataka and parts of Tamil Nadu saw stagnant Monsoon during this period. The formation of Cyclone Vayu in the Arabian Sea to a large extent hindered the progress of Southwest Monsoon.
Although June 19 onwards monsoon made steady progress, heavy rains remained absent from South Peninsula. Only coastal Karnataka and parts of Kerala were the two pockets that observed some decent rains during this period.
The current situation does not look any different either. There is no good rain expected in most parts of South Peninsula for at least one week because of weak Monsoon-like conditions. Rains will only be confined to Coastal Karnataka.
Chances of revival can only be expected after July 16. Till then the rainfall deficiency in the state is only going to mount.
