IMD says rains to be normal in Aug-Sept, contradicts Skymet

New Delhi: Monsoon rain would be normal in August and September, India Meteorological Department (IMD) said on Saturday.
On the other hand, Skymet, a private weather forecasting agency, has contradicted the IMD predicting ‘below normal’ rains in the remaining two months.

In the second Long Range Forecast for rainfall during the second half of the Southwest Monsoon season, the IMD said the scenario realised till the end of July suggested that distribution of rainfall was very good across the country except Bihar, Jharkhand and north-eastern states.

The favourable distribution of rainfall was expected to continue for the next two months, it said, raising hopes for agricultural operations during the kharif season.

“The rainfall during August-2018 is likely to be 96 plus/minus 9 pc of LPA and expected to be higher than predicted in June. Quantitatively, the rainfall for the country as a whole during the second half of the season is likely to be 95 per cent of LPA (Long Period Average) with a model error of plus or minus 8 pc,” IMD said.

Skymet contradicts
