New Delhi: The coming monsoon rains are likely to be “below normal” if predictions are to be believed. Skymet has predicted that this would fall 7% short of the 89 cm the country usually gets from June to September.

“In terms of geographical risk, Skymet expects that eastern India, along with a major portion of Central India, is likely to be at a higher risk of being rain deficient, especially during the first half of the season. The onset month of June is going to have a very sluggish start and deficit rains are likely to spill into July,” the company said in a statement.

August would be just a shade better than September, said the statement.
This would mean a 15% chance of a drought (seasonal rainfall less than 90% of the average), 30% chance of normal (seasonal rainfall that is between 96%-104% of the long period average or LPA), and 55% chance of below normal (seasonal rainfall that is between 90%-95% of LPA).
As far as rain is concerned, here’s a monthly prediction: 77% of its average of 164 mm in June; 91% of its average of 289 mm in July; 2% more than its average of 261 mm in August and 99% of its 173mm average in September.
According to Skymet Managing Director Jatin Singh, El Nino — the warming of the central Pacific Ocean that’s frequently associated with drying monsoon rains — is the culprit.
“The Pacific Ocean has become strongly warmer than average. The model projections call for 80% chance of El Nino during March-May, dropping to 60% for June to August,” he said. El Nino would form from March to May and there was a “less than 50% chance” of a strong El Nino from June-August.
An El Nino is declared when three straight months register a 0.5-1 degree C rise in sea surface temperatures in the Central Pacific.
The agency said it expects “weak El Nino conditions” to prevail during May-June.
