The India Meteorological Department (IMD) on Monday, said a cyclonic circulation has been observed over the southeast Arabian Sea extending up to middle tropospheric levels.
Under its influence, there is a high probability of a low-pressure area forming over the same region during the next 24 hours. It is likely to move nearly northwards and intensify into a depression over the southeast and adjoining east-central Arabian Sea over the subsequent 48 hours.
If the low-pressure area consolidates and intensifies into a cyclonic storm, it will be designated as Cyclone Biparjoy.
June 03-07: A low-pressure area is expected to form, leading to light drizzles over Mumbai.
June 08-10: Heavy rains are anticipated over Maharashtra, with Pune and Mumbai likely to experience intense rainfall during this period.
June 11-12: Mumbai and the Konkan region are expected to receive very heavy rainfall. There is a possibility of flash floods occurring in the Konkan area during these dates.
“The track of the cyclone is not clear as of now. Few models are indicating its movement in the northerly direction along the West Coast of the country. Some models indicate its movement to the north initially and re-curvature to the north-northeast direction towards Omen and Yaman," reported private weather forecaster Skymet.
It further said rain activities will certainly intensify along the West Coast of the country from Kerala to Maharashtra. The cyclone will help the monsoon current to reach Mumbai on time.
Sea conditions will be rough to very rough along Karnataka and Maharashtra coast between June 8 and 10. And over the Gujarat coast between June 9 and 12.
The name of the cyclone has been given by Bangladesh. According to World Meteorological Organization, weather forecasters give each tropical cyclone a name to avoid confusion. In general, tropical cyclones are named according to the rules at the regional level.
In the Atlantic and the Southern Hemisphere (Indian Ocean and South Pacific), tropical cyclones receive names in alphabetical order, and women's and men's names are alternated.
Nations in the Northern Indian Ocean began using a new system for naming tropical cyclones in 2000; the names are listed alphabetically country-wise, and are neutral gender-wise.
The common rule is that the name list is proposed by the National Meteorological and Hydrological Services (NMHSs) of WMO Members of a specific region, and approved by the respective tropical cyclone regional bodies at their annual/biannual sessions.
