Depression over Arabian Sea likely to intensify into cyclonic storm- IMD
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 on Tuesday, June 6, 2023
In a bulletin, the Met office said the depression lay about 920 km west-southwest of Goa, 1,120 km south-southwest of Mumbai, 1,160 km south of Porbandar and 1,520 km south of Karachi, Pakistan, at 5-30 am.
“It is likely to move nearly northwards and intensify into a cyclonic storm during the next 24 hours over east-central Arabian Sea and adjoining southeast Arabian Sea,” it said.
The IMD had Monday, June 5, said the formation of the low-pressure system over the southeast Arabian Sea and its intensification is expected to critically influence the advance of the monsoon towards the Kerala coast.
The weather department, however, did not give a tentative date for the arrival of the monsoon in Kerala.
Monsoon onset in Kerala on June 8-9- Skymet
Private forecasting agency Skymet Weather said the monsoon onset over Kerala may happen on June 8 or June 9 but it is expected to be a “meek and mild entry”.
“These powerful weather systems in the Arabian Sea spoil the advancement of the monsoon deep inland. Under their influence, the monsoon stream may reach coastal parts but will struggle to penetrate beyond the Western Ghats,” it said.
Skymet had earlier predicted the monsoon onset over Kerala on June 7 with an error margin of three days.
“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.
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.
