According to sources the southwest monsoon is likely to hit kerala on june 1, the india Meteorological Department said on Thursday. This is because of a cyclonic circulation over the Bay of bengal which has helped in the faster progress of the monsoon. The country is also likely to receive normal monsoon this year. The IMD, in its onset date forecast on May 15, had said the monsoon is likely to hit the southern state on june 5, four days after its normal arrival.
"A low-pressure area is likely to form over southeast and adjoining east-central arabian sea from May 31 to june 4. In view of this, conditions arevery likely to become favourable from june 1 for the onset of southwest monsoon over kerala," the IMD said.A low-pressure area is the first stage of any cyclone. It is not necessary that every low pressure intensifies into a cyclonic circulation. A low-pressure area has also formed over the west-central Arabian Sea. It is very likely to concentrate into a depression over the North Westward same region during next 48 hours. It isvery likely to move towards south oman and east yemen coast during next three days, the IMD added.
