Early indications of a monsoon vortex formation in south Arabian sea is forming in a couple of days, 4th/5th June.
This will lead to the Monsoon advance into Kerala by 4th June.
This system, AS-1, can strengthen and form into a depression as it tracks NNW. Sea surface temperatures in South Arabian Sea of 30/31c presently are very conducive for the possibility of a cyclone forming ( early to commit now).
