New Delhi | Jagran News Desk: The Indian Meteorological Department (IMD) on Friday said that the southwest monsoon will likely hit Kerala on June 5, a delay of four days as compared to its normal onset date. According to the normal onset date, monsoon makes an arrival in Kerala on June 1. 

The weather department further said that the monsoon will likely be normal in this year.

"The onset of southwest monsoon over Kerala this year is likely to be slightly delayed as compared to normal date of onset. The monsoon onset over Kerala this year is likely to be on June 5 with a model error of plus or minus 4 days," the IMD said in a statement.

The arrival of the southwest monsoon marks the commencement of the four-month long rainfall season in India from June to September.

In a statement, the IMD said that the monsoon will arrive in Andaman and Nicobar islands by May 16, six days before its new onset date of May 22 due to a cyclonic storm in the Bay of Bengal.

Even last year, the monsoon had reached the Andaman and Nicobar archipelago on May 18, two days ahead of its then normal onset date of May 20. But due to its sluggish pace, it reached Kerala on June 8. It covered the entire country by July 19.

India receives 75 per cent of its rainfall from the southwest monsoon during June to September. It is not only crucial for farming in the country, but also for replenishing reservoirs, and more importantly to the economy which is still largely dependent on agriculture.

Meanwhile, this is also the first time that the IMD has revised the dates of onset and withdrawal dates of the monsoon for several parts of the country based on the data from 1960 to 2019. The previous dates were based on the data from 1901 to 1940.   

In states like Maharashtra, Gujarat, Madhya Pradesh, Chhattisgarh, Telangana, Andhra Pradesh, Odisha, Jharkhand, Bihar and parts of Uttar Pradesh, monsoon will be delayed by 3-7 days compared to the existing normal dates.

For the national capital, the new normal onset date for monsoon has been revised from June 23 to June 27 -- a delay of four days. Similarly, dates have been revised for Mumbai and Kolkata from June 10 to 11, and for Chennai from June 1 to 4.  

However, over extreme northwest India, the  monsoon will arrive a little earlier, on July 8, as compared to the existing date of July 15. The new date for monsoon withdrawal from south India is October 15.
