​Visakhapatnam: The southwest monsoons will onset over Andaman and Nicobar Islands between May 18 and May 20 and arrive over Kerala by May 30, slightly before the official onset date of June 1, said a private weather website www.skymet.com in its latest report released on Thursday.

According to its prediction, the monsoons would touch Ralayaseema on June 1. Along with Kerala, monsoon would also simultaneously cover some parts of Northeast India.

As it moves further, it will cover most parts of South India and entire north-eastern states by first week of June. The report said eastern arm of the monsoon will move on at a faster pace as compared to its western arm. It is expected to reach Kolkota by June 10. Mumbai will have to wait a little more and will witness onset with a short delay between June 12 and June 14.

Advancement of monsoon is expected to be slow over Gujarat, Madhya Pradesh and Uttar Pradesh. Most parts of these states will be covered by June 25.

It is likely to mark its onset over Delhi July 1. Subsequently, almost all parts of the country barring west Rajasthan will be covered between July 1 and July 7. Further, it will cover the entire country before July 15.

The presence of active Inter-Tropical Convergence Zone (ITCZ) in the Indian Ocean is primarily responsible for bringing the monsoon season of 2016 little early. The report further added that several active cyclonic circulations can be seen embedded in ITCZ. Besides this, cloud configuration, atmospheric conditions and oceanic parameters are also indicating towards favourable weather conditions for the early arrival of monsoon.

However, onset of monsoon does not have any direct link with its progress or performance. An evolving and strong El-Niño in 2014 and 2015 respectively had marred the monsoon performance resulting in two consecutive drought years. El-Niño is on decline now and is likely to become neutral sometime around June. This will lead to better conditions and might bring above normal rainfall.
