Southwest monsoon rains are expected to hit the southern coast of Kerala in two days, reports said citing an official of the India Meteorological Department (IMD).
“Conditions have now become favourable for the onset over the Kerala coast,” reports said quoting D.S. Pai, lead forecaster of the IMD.
He said he expects monsoon rains to hit the coast by June 6.
The weather department also said on Monday that the monsoon has advanced into some parts of Arabian Sea.
Earlier reports stated that while the southwest monsoon may only take a token onset during the two-day window mounted by the India Meteorological Department (IMD) beginning today, the full-scale monsoon onset would not set in until June 10.
IMD, too, has said in its extended outlook that rains along the west coast are expected to increase around during this period.
The monsoon would have to decouple from a raging typhoon ‘Mawar’ in the northwest Pacific typhoon, for this occurrence to take place.
The onset of itself is attributed to the ‘pull’ force that ‘Mawar’ exerts on the flows affecting the tropics, of which Indian (Asian) monsoon is a part.
It is but natural that ‘Mawar’ would continue to draw the flows across south Bay of Bengal, South China Sea/northwest Pacific.
The typhoon would have to weaken and die out before the flows can recoup and converge over the Arabian Sea and the Bay to power the Indian monsoon.
In a country where agriculture and farming account for 15% of the $2tn economy, timely and sufficient rainfall is extremely crucial as 55% of the arable land depends on rains for water needs.
