The SW monsoon had arrived in Kerala on June 5-6 2010 and NOT on 30th May 2010 as per IMD. within the monsoon ridge, cyclone Phet was shaping up on 30th May 2010 and then Phet moved towards Oman coast for a landfall. Presence of low pressure near Kerala and rains due to it is not regarded as Monsoon as winds both at Surface and Mid levels were in anti-circular motion and not attracted towards Kerala and Interior India.
Phet weakened and got over on 6th June while its unusual path and two landfalls helped the SW monsoon. If phet w'd have moved northwards towards Pakistan by crossing Arabian from South to North, then it w'd have used all the moisture in arabian sea making a big delay for monsoon formation and advancement.
Phet is causing a very heavy rainfall in open waters of Arabian Sea and caused in Oman also.
