The depression over east central Arabian Sea moved west-northwestwards and intensified into deep depression over the same area roughly 500kms away from Indian west coast. High sea surface Temperature (SST), Low Vertical Wind Shear (VWS) are the crucial factors which feeds and maintains any tropical systems. In this case the SST is seen satisfying the conditions for the disturbance but VWS is just marginally favorable. So this disturbance may see slight intensification for next 18-24 hrs which could elevate this to TROPICAL STROM category. Thereafter the system would move into poor environment which is surrounded by dry air, leading to weakening of the system gradually as it moves northwestwards in next 2-3 days.
No significant rainfall warning for most parts of southern peninsular states. However Thunderstorms would occur over isolated parts of Northern parts of TN and Rayalaseema.
