The Southwest Monsoon has entirely covered southeast Bay of Bengal. It has advanced to some parts of westcentral and northeast Bay of Bengal and some more parts of eastcentral and southwest Bay of Bengal.
As already highlighted by Skymet Meteorology Division in India, the advancement of Southwest Monsoon has been sluggish after its arrival before the due date in the Andaman Sea on 18th May. The Monsoon air mass usually enters Sri Lanka by 25th May but this time it could miss the date as the Monsoon line is far from it at the moment.
Weathermen at Skymet are of the view that prior to the onset, weather systems such as the current depression in the Bay of Bengal will help the cross equatorial flow to strengthen, after which the strong southwesterly winds will sweep across Kerala coast, announcing the arrival of Monsoon.
The map in the article shows that after it’s on time arrival, the eastern arm of the Monsoon has made more progress than the western arm and has reached Myanmar early this year. The green line shows the actual Monsoon line which indicates that the eastern arm of Monsoon line has already entered Myanmar and is close to northeastern states, while the western arm has covered some parts of southwest Bay of Bengal. The red-dotted Monsoon line in the map has been drawn by Skymet Meteorology Division in India.
