The southwest monsoon is likely to reach Jharkhand a little late this year, weathermen have indicated. Usually southwest monsoon sets over Kerala on June 1, and takes another 10-12 days to reach Jharkhand. If the onset of monsoon is delayed in Kerala, it will also impact Jharkhand where it is also likely to get delayed. Under normal weather conditions, after hitting Kerala, it takes 10-12 days for the monsoon currents to reach Jharkhand and neighbouring Bengal. He add that if conditions remained favourable, and the surge was maintained, the monsoon could reach Jharkhand by the third week of June.
