Cyclone 'Biparjoy' has rapidly intensified into a severe cyclonic storm, with meteorologists predicting a "mild" monsoon onset over Kerala and "weak" progress beyond southern peninsula under its influence.
Cyclone 'Biparjoy' is the first storm brewing in the Arabian Sea this year.
In an update, the India Meteorological Department (IMD) said, "Cyclonic storm Biparjoy over east-central and adjoining southeast Arabian Sea moved nearly northwards with a speed of 2 kmph during the last six hours, intensified into a severe cyclonic storm and lay centred over the same region at 0530 hours, about 890 km west-southwest of Goa, 1,000 km southwest of Mumbai, 1,070 km south-southwest of Porbandar and 1,370 km south of Karachi".
The Met office said it is likely to move nearly northwards and intensify into a very severe cyclonic storm. It would then move north-northwestwards during the subsequent three days.
However, the IMD has not yet predicted any major impact on countries adjoining the Arabian Sea, including India, Oman, Iran and Pakistan.
Meteorologists say the tentative track of the system will be in the northward direction but storms at times defy the predicted track and intensity. Forecasting agencies said the storm has been undergoing "rapid intensification".
Cyclone Biparjoy intensified by 40 knots (74 kmph) since Tuesday morning, according to the Joint Typhoon Warning Centre (JTWC), the US Department of Defense's agency responsible for issuing tropical cyclone warnings for the Pacific and Indian Oceans.
Scientists say cyclonic storms in the Bay of Bengal and the Arabian Sea have been intensifying rapidly and retaining their intensity for a longer duration due to climate change.
According to a study 'Changing status of tropical cyclones over the north Indian Ocean', the Arabian Sea saw a significant increasing trend in the intensity, frequency, and duration of cyclonic storms and very severe cyclonic storms during the 1982-2019 period.
