The monsoon is expected to further advance across Bihar, Chhattisgarh and Jharkhand over the next three to four days marking intensified rainfall activity, meteorologists said today.
Rainfall from June 17-23 was subdued, 21 per cent below the expected normal levels.
But weather features suggest that a spell of wet weather lies in the week ahead. “Overall, things appear to be getting better for the season,” said Damodar Pai, a senior scientist at the India Meteorological Department (IMD), Pune.
He said sea surface temperatures in the eastern Pacific Ocean appeared to be cooling — a phenomenon known as La Nina and associated with more rainfall over India.
The IMD is scheduled to deliver on Friday an updated long-range forecast of the 2010 monsoon.
Another weather parameter called the Madden-Julian Oscillation — a pattern of anomalous rainfall that circles the globe — is also currently over the Indian Ocean and could contribute to an intensification and further advance of the monsoon next week, Pai said.
