The depression over the southeast Arabian Sea which is delaying the onset of monsoon over India is moving roughly northward and intensifying into a cyclonic storm over the course of the next twelve hours according to a forecast issued by the India Meteorological Department IMDThe IMDs Bulletin stated that the storm has a potential to impact the monsoon as it approaches the Kerala coastUnder the influence of cyclonic circulation over the Southeast Arabian Sea a LowPressure area had formed over the same region at 530 pm IST on June 5 2023 and the associated cyclonic circulation extends upto midtropospheric levels the IMD bulletin statedThe southwest monsoon normally sets in over Kerala on June 1 with a standard deviation of about seven days This year in the month of May IMD had said that the monsoon may arrive in Kerala by June 4 with a model error of four daysHowever the monsoon missed its onset date in Kerala on Sunday with the Indian Meteorological Department Anticipating a further delay of 3 to 4 days This will further delay the onset of monsoon in Mumbai and other parts of Maharashtra leading to sweltering and stuffy nights to continue until the monsoon sets in the meteorologists have saidWith the developing system the cyclone will suck up all the moisture from around the Konkan coast After the system moves away the winds will reorganize in a weeks time making conditions favourable for rain So according to me the probability of a monsoon now would be around or after June 15 said Rajesh Kapadia of Vagaries of Weather a popular private weather blogTalking about the developing cyclonic storm which will be named Biparjoy Sushma Nair a scientist with IMDrsquos regional meteorological center at Colaba said The depression over the southeast Arabian Sea moved nearly northward with a speed of 11 kmph and lay centre at 0830 am IST today June 6 2023 over the same region near latitude 115degN and longitude 660degE about 950 km westsouthwest of Goa 1100 km southwest of Mumbai 1190 km southsouthwest of Porbandar and 1490 km south of Karachi It is likely to move nearly northward and intensify into a cyclonic storm over the eastcentral Arabian Sea and adjoining southeast during the next 12 hoursElaborating further about the developing system Skymet Weatherr a private weather forecasting agency said The depression is expected to become a tropical storm in the next 24 hours Depression is moving in favourable environmental conditions with very warm sea surface temperature and low vertical wind shear The potential for a cyclonic storm in the next 24 hours is rather high The weather system is likely to move northward keeping a safe distance from the coast for the next 24 hoursThe meteorologists from Skymet said Tropical storm Biparjoy will be a slowmoving system and is expected to reach abeam Mumbai on Saturday or Sunday remaining deep over the ocean waters Though these storms are notorious for defying track and intensity but it is likely to remain over the open waters of the Arabian Sea for the next 3 days The tropical storm will be kept under close observation from hereon Such monsters do have a history of threatening the Gujarat Coast or recurve to scare Pakistan and Makran CoastAccording to Vagaries of weather Low wind shear and very high sea surface temperature SST of 31 degC 32degC will favour the intensification of AS1 into a strong cyclonemay further reach extremely Severe Cyclone Intensity over the next three days equivalent to category 3 hurricane intensity approximately Vagaries of weather predicted
