The country is expected to get excess rainfall this monsoon than earlier predicted with September tipped to be the wettest month. Met office said yesterday that the south-west monsoon has entered a weak phase on June 18 after covering half of the nation but there are already signs of revival in parts of Madhya Pradesh, Bihar and Jharkhand.<br/> In an update to its April forecast, the India Meteorological Department revised its predictions and pegged the quantum of rains for the country for June-September period at 102 per cent of the Long Period Average (LPA). The LPA is the average rainfall received across the country over a 50-year period. The LPA has been calculated at 89 cm. In April, the IMD had said the country would receive 98 per cent rains of the LPA.<br/>IMD Director General Ajit Tyagi told reporters that Monsoon revival is already taking place and we expect good rains in July and August. Tyagi said September could be the wettest month this monsoon season as La Nina conditions are developing in the Central Pacific ocean. <br/>A good rainfall in July is very crucial for agriculture as sowing for the kharif crop is at its peak during this period. Over 235 million farmers across the country have been expecting a normal monsoon season in the backdrop of severe drought last year.<br/>
