Officials in the weather department said the monsoon is expected to be below normal because of the El-Nino effect, which is generally associated with the warming of ocean water.
"The monsoon seasonal rainfall is likely to be 95 per cent of the Long Period average with an error of plus or minus 5 percent," the Meterological Department said in a statement here.
The rainfall between 90-96 percent is catergorised as below normal and rainfall between 96-104 per cent is termed as normal rainfall.
Last year, the Met department had forecast 98 per cent rainfall but it exceeded and the country received over 106 per cent rainfall.
Monsoon is crucial for agriculture, particularly the kharif crops such as rice, soyabean, cotton and maize because almost 60 per cent of the farm land in the country is rainfed.
"Latest forecast from a majority of the models also indicate warming trend in the sea surface temperature over the equatorial Pacific reaching to El-Nino level during the South-west monsoon with a probablity of around 60 per cent," the IMD said.
