New Delhi, June 05 (ANI): Indian weather official on Thursday said southern coast could witness the arrival of this year's monsoon in the next day or so after sporadic rains in recent days heralded the arrival of the wet season that is crucial to farmers. Scientist at the meteorological department in New Delhi, BP Yadav, said conditions have turned favourable for the monsoon onset in about 24 hours. Experts said the spread of rainfall near the southern coast does not qualify for a formal announcement of the monsoon onset. Last month, the Meteorological Department predicted a delayed onset for this year's monsoon over the Kerala coast around June 05.
