Kolkata: Monsoon may arrive in Kolkata and south Bengal sooner than normal. It is expected that Kerala and Bengal will welcome an early arrival of rains as south-west monsoon currents reached Nicobar Islands.
Kolkata and south Bengal could be lashed by monsoon rains by June 8. Monsoon rains in India are expected to be average in 2018, reported by Skymet. Skymet Weather has forecast a 20 percent chance of an above normal monsoon, and a 5 percent chance of excess rain for India in 2018.
Last year, India got 95 per cent of it’s normal monsoon quota. June and July got more than it’s usual quota while August and September saw significant deficits. Before 2016, India had suffered back-to-back drought years for only the fourth time in more than a century, hurting incomes and driving farmers to suicide.
The three major factors that influence the progress of monsoon currents are cross-equitorial flow of wind, low-pressure situation and the heat condition in north-west India. The Skymet forecast has, however, predicted less rainfall in southern states. According to the predictions, Coastal Karnataka, Kerala and south interior Karnataka will receive less rainfall.
South-west monsoon hit Nicobar Islands and will cover the entire Andaman and Nicobar region in the next three days. It is due to hit Kerala on May 29, but could reach the state even before that. Last year, monsoon struck Kolkata on June 12.
A statement issued by the India Meteorology Department (IMD) on Friday declared the onset of southwest monsoon over South Andaman Sea and Nicobar Islands. Some parts of south Bay of Bengal, Andaman Sea and Andaman & Nicobar Islands could be hit within the next 48 hours, it said. Kerala is due to receive monsoon on May 29.
