"The southwest monsoon is likely to arrive within this bracket. Onset criteria require stipulated rainfall on two consecutive days over Lakshadweep, Kerala and coastal Karnataka. Accordingly, the spread and intensity of rainfall may match these requirements on June 8 or June 9. However, the onset of the annual event may not be loud and sound. It may only make a meek and mild entry to start with," the private weather forecasting agency said.
D S Pai, senior scientist, IMD, said Kerala received good rain on Monday too and conditions are favourable for the onset of monsoon over the next two to three days.
AdvertisementThe southern peninsula will get rain under the influence of the cyclonic storm and a low-pressure system developing in the Bay of Bengal. However, further progress of the monsoon beyond the southern peninsula will happen after the cyclone degenerates, Pai said.
The southwest monsoon normally sets in over Kerala on June 1 with a standard deviation of about seven days. In mid-May, the India Meteorological Department (IMD) said monsoon might arrive in Kerala by June 4.
The southeast monsoon arrived in the southern state on May 29 last year, June 3 in 2021, June 1 in 2020, June 8 in 2019 and May 29 in 2018.
Scientists say a slightly delayed onset over Kerala does not mean that the monsoon will reach other parts of the country late. It also does not impact the total rainfall over the country during the season.
India is expected to get normal rainfall during the southwest monsoon season despite the evolving El Nino conditions, the IMD had earlier said.
Northwest India is expected to see normal to below-normal rainfall. East and northeast, central, and south peninsula are expected to receive normal rainfall at 94-106 per cent of the long-period average of 87 centimetres.
