New Delhi: The Indian Meteorological Department (IMD) said on Sunday that the southwest monsoon may arrive in Kerala on May 27. According to IMD data, if the monsoon reaches Kerala, this will be the earliest attack on mainland India since it began on May 23, 2009.
The arrival of the main stormwater system on the Indian continent was officially announced to Kerala (usually around June 1).
Monsoons usually cover the entire country before July 8. It began its withdrawal from northwest India around September 17 and completed on October 15.
The monsoon was placed in the southern states on May 30 last year. June 8, 2023; May 29, 2022; June 3, 2021; June 1, 2020; June 8, 2019; and May 29, 2018.
An IMD official said there is no direct relationship between the national rainfall date and the total national rainfall during the season.
“The monsoon that reaches Kerala does not mean that it will cover the rest of the country accordingly. It is characterized by large-scale changes as well as global, regional and local characteristics,” the official said.
IMD predicted cumulative rainfall in 2025 in April that the monsoon season was higher than normal cumulative rainfall, ruled out the possibility of El Nio conditions, which were related to lower than normal rainfall in the Indian subcontinent.
“In the four-month monsoon season (June to September), India may see the above normal rainfall, with a cumulative rainfall estimated at 87 cm long-term average of 105% (model error of 5%).
According to the IMD, 96% to 104% of the 50-year average of 87 cm rainfall is considered “normal”.
Rainfall is less than 90% of the long-term average is considered a “undersuit”. Between 90% and 95%, “below normal”; between 105% and 110% is “above normal”; more than 110% is considered “excessive” precipitation.
