India is all set to experience normal rainfall, at least 100 per cent of its long-period average (LPA) during June-September, even if there is below normal monsoon in August as predicted by the weather bureau. Besides, the good spell in July may help the overall monsoon rainfall, as predicted by India Meteorological Department (IMD).

“If everything goes on as has been forecast, there could be a normal monsoon. But, we have to see how it performs in August,” said a senior scientist in IMD.

Releasing the forecast, IMD director general M Mohapatra said the rainfall during August may be 92 per cent (234.51 mm) of the month’s LPA of 254.9 mm. If that proves correct, the rainfall during June -August will turn out to be 701.61 mm.

Mohapatra said for August and September together, the rainfall may be 94-99 per cent of the LPA of 422.8 mm, which means actual rainfall could be 401.7-418.6 mm. If the August forecast proves correct and a minimum of 94 per cent precipitation happens in the last two months, there may be at least 167.2 mm of rainfall in September, which is near its LPA of 167.9 mm.
