THIRUVANANTHAPURAM: The cross equatorial southwest monsoon flow into the Indian subcontinent is strengthening, promising a good spell of rain that could last for at least a week for Kerala, judging from the weather prediction models of the India Meteorological Department (IMD), based on Tuesdays atmospheric conditions.
The models indicate the possibility of a low pressure system developing over the Arabian Sea centred at a point some 400 km off the Karnataka coast by June 13.
The system shows the potential to strengthen into a depression and even a deep depression.
It may move parallel to the west coast northwards pulling the monsoon currents into Konkan and Goa and even Mumbai in Maharashtra by the beginning of next week, exposing the regions to the south, including Kerala, to unhindered flow of the monsoon currents.
The winds are also seen to pick up in speed during the course of the week, propelled by the evolving system in the Arabian Sea. This means substantial rain in the midlands and high ranges of the State.
