Port Blair, the capital of the Andaman & Nicobar Islands has recorded 20 mm of rain in the last 24 hours and good amounts of showers are expected to continue in the city during the next 48 hours. The city has been experiencing pre-monsoon rains for last ten days with 41 and 25 mm of rain received on 14th and 7th May, respectively.
Skymet Meteorology Division says that a cyclonic circulation near the Andaman Sea has emerged at a medium level. Such weather systems expedite and enhance the progress of Southwest Monsoon. The current system seems to be relocating and reorganizing at the moment, bringing slight uncertainty over the advancement of Monsoon.
Weathermen at Skymet are of the view that prior to the onset, such weather systems either in the Bay of Bengal or in the Arabian Sea help the cross equatorial flow to strengthen, and thereafter the strong southwesterly winds sweep across Kerala coast, announcing the arrival of Monsoon.
