“We are expecting moderate to heavy rain, between 30 to 60mm in Konkan and Goa and along the Karnataka and Kerala coast from tomorrow (17th September) onwards. Rainfall would be most intense on Wednesday and lesser so on Tuesday and Thursday”, says Mahesh Palawat, Head of the forecasting at Skymet Weather.
“Though, it is important for us to know that this rain is not because of a monsoon trough, as monsoon in India is now showing a declining trend. This rain is because of an offshore (coastal) trough which has become active along the west coast of south India”, explains Palawat.
Further, we are told, as the trough loses its strength, rain is expected to reduce drastically after 48 to 72 hours. But till then, maximum temperatures may fall sharply by 2 to 4 degrees in coastal and interior Karnataka and many parts of Kerala. Mercury levels in Bangalore may drop down to 25 degrees Celsius tomorrow and day after.
Also, days will be windy with speeds reaching up to 40 kmph and skies will be mostly cloudy to overcast.
Rainy days and mercury levels below normal are favourable in other states of south India too. Andhra coast, north Tamil Nadu coast and Rayalseema are expected to witness scattered light to moderate showers this week, due to mixing of two air masses(dry and humid), i.e. the easterlies and westerlies. Rain is also forecast for major cities of Chennai and Hyderabad.
