This information was given by the Union Minister of State for of Science & Technology and Earth Sciences Shri Y.S.Chowdary in a written reply to a question in Lok Sabha today
Excepting North West India, all other homogenous regions have so far experienced below normal monsoon season rainfall.
Below normal rainfall over India as a whole realized so far during monsoon-2015 is largely attributable to the weak monsoon scenario prevailed for over 3-weeks during 26 June -18 July 2015. The rainfall forecast over the country as a whole during July is likely to be 92% of LPA and 90% of LPA during August both with a model error of ±9%.
El Nino has adversely affected the monsoon so far. As per the model forecasts, it is also expected to affect the monsoon in the coming months. According to the latest status, moderate EL Nino conditions are persisting in the Pacific and latest forecasts indicate that the EL Nino conditions are likely to strengthen further during the remaining months of the monsoon season and post-monsoon season.
Gramin Krishi Seva Scheme (GKMS) is rendered now on twice - weekly basis in collaboration with State Agricultural Universities (SAUs), institutions of Indian Council of Agricultural Research (ICAR) etc. Realized weather of the previous week and quantitative district level weather forecast for next 5 days in respect of rainfall, maximum temperature, minimum temperature, wind speed, wind direction, relative humidity and clouds as well as weekly cumulative rainfall forecast are provided.
