Monsoon to make early onset this year, likely to hit Kerala by May 31, above-normal rainfall predicted | IMD
According to The India Meteorological Department (IMD), the monsoon is expected to arrive in Kerala around May 31 with an error of plus minus four days.
The southwest monsoon is expected to make onset over Kerala around May 31, the India Meteorological Department (IMD) mentioned in a press release on Wednesday.
The southwest monsoon arrives in Kerala on June 1 with a standard deviation of about 7 days; thereafter it advances northwards, usually in surges, and covers the entire country around July 15.
This year however, according to the IMD’s projections, the southwest monsoon is expected to arrive over Kerala around May 31, with a model error margin of ± 4 days. This onset date serves as a crucial indicator for the progression of the monsoon across the country, bringing relief from scorching summer temperatures as it advances northward.
The 2024 southwest monsoon seasonal (June to September) rainfall over the country as a whole is most likely to be above normal (>104% of the Long Period Average (LPA)). Quantitatively, the seasonal rainfall over the country as a whole is likely to be 106% of LPA with a model error of ± 5%. The LPA of the season rainfall over the country as a whole for the period 1971-2020 is 87 cm.
The IMD said that its operational forecasts of the date of monsoon onset over Kerala during the past 19 years were proved to be correct with the exception of 2015.
