IMD has predicted 'satisfactory' monsoon this year

The Indian Meteorological Department has predicted that country's South-west monsoon would be satisfactorythis time around. About 96 percent rainfall across the country is expected and the IMD has predicted a variation range of 4 percent. The numbers are promising especially for parts of the country that have seen drought and inadequate rainfall in the last few years.

Possibility of El-Nino affect?

There are high chances that South India will witness a normal monsoon or even have excessive rainfall till September. Senior meteorologist Kanti Prasad while speaking at a seminar organised by the Weather Risk Management Services (WRMS) Pvt Ltd. said that there could be rain deficit in October post monsoon, November could see ample rainfall again.

There is a distinct possibility of a monsoon deficit with moderately negative side of normal due to El Nino, he said while going by the forecast projected by the Indian Meteorological Department (IMD).

South-west monsoon will arrive in Kerala

The South-west monsoon will arrive in Kerala on May 30 according to IMD predictions. The department has, however, also added that the state may witness rainfall three days after the arrival of the Monsoon. Another three days later, Karnataka will witness rainfall, according to the Met department's predictions.

Rain deficit in some regions possible

Despite predictions of 96 percent average rainfall and 4 percent variation, this year's South-west monsoon is being treated as satisfactory. When rainfall is lesser than 19 percent of an average, it is considered a deficit.

Southwest monsoon is one of the most anticipated weather phenomena and an economically important pattern every year.
