Between June 1 and 25th, South Peninsula is rain deficient by 14%. However, Rayalaseema and Tamil Nadu are large rain excess. In fact, Pre-Monsoon rains remained good over South Peninsula and now Monsoon is also in the normal or large excess category over most of the states except Andaman and Nicobar Islands, Karnataka and Kerala which are rain deficient.
Monsoon surge has weakened over South Peninsula. Rain activities have reduced over Tamil Nadu, Rayalaseema, Interior Karnataka, Lakshadweep, and parts of Andhra Pradesh. However, the offshore trough which is extending from Gujarat to North Kerala coast will continue to give good rain over coastal parts of Karnataka.
Interior Karnataka, Rayalaseema, Telangana and Tamil Nadu will witness isolated rainfall until June 29. Thereafter, rain activities are expected to revive over South Peninsula. By the end of June, rain deficiency of South India may increase further, however, we expect decent rainfall during first week of July over South Peninsula.
