Furthermore, the department has highlighted the possibility of strong winds and rough seas along the Kerala coast on June 6 and 7.

A depression over the southeast Arabian Sea, south of Porbandar in Gujarat, is likely to move northwestward and intensify into a cyclonic storm, the India Meteorological Department said.

The cyclonic storm will be called Cyclone Biparjoy, a name given by Bangladesh.

In a bulletin, the Met office said the depression lay about 950 km west-southwest of Goa, 1,100 km south-southwest of Mumbai, 1,190 km south of Porbandar and 1,490 km south of Karachi, Pakistan, at 8:30 am.

"It is likely to move nearly northwards and intensify into a cyclonic storm over east-central Arabian Sea and adjoining southeast Arabian Sea," it said.

The Met office said the cyclonic storm will intensify into a severe cyclonic storm by Thursday morning and very severe cyclonic storm by Friday evening.

Rain in Kerala

They have also cautioned that heavy rainfall is possible at isolated locations from June 6 to 10.

The IMD has issued a yellow alert for the following districts:

  • June 6, 2023: Pathanamthitta, Idukki
  • June 7, 2023: Pathanamthitta, Alappuzha
  • June 8, 2023: Alappuzha, Ernakulam
  • June 9, 2023: Thiruvananthapuram, Kollam
  • June 10, 2023: Pathanamthitta, Idukki
These districts are at risk of isolated heavy rainfall. Heavy rain is defined as precipitation ranging from 64.5 mm to 115.5 mm within a 24-hour period.

High wave warning

The National Oceanic and Atmospheric Research Center has reported the possibility of high waves measuring 0.8 to 1.4 metres and a storm surge along the Kerala coast until 11:30 pm on Tuesday, with speeds varying between 15 cm/sec and 25 cm/sec. Along the southern Tamil Nadu coast, high waves of 0.5 to 1.5 metres and storm surge with speeds ranging from 10 cm/sec to 45 cm/sec are expected until 11:30 pm on Tuesday.

Due to the expected turbulent conditions in the Arabian Sea, the IMD has strongly advised fishermen not to venture out into the sea from the Kerala coast until further notice.

Monsoon progress

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.
