According to the report: The moderate La Nina conditions developed in the equatorial Pacific during last year started weakening in the early part of this year. The conditions have now gone to a weak state from its previous moderate.
The extreme sea surface temperature conditions over the Pacific and Indian Oceans, particularly ENSO conditions (El Nino or La Nina) are known to have a strong influence on the Indian summer monsoon. For that very reason, IMD is carefully monitoring the sea surface conditions over the Pacific and Indian oceans.
