Under the influence, the Andaman & Nicobar Islands including capital Port Blair could experience heavy rain during the next two days. The southwesterly winds would be blowing at a speed of 25 to 30 kmph during this period. Port Blair again recorded 20 mm of rain from 8:30 am on Monday to 8:30 am on Tuesday. Day temperature in the city on Monday dropped significantly to record 26°C, five notches below normal. The other weather station Car Nicobar reported 80 mm while Hut Bay recorded 50 mm of rain during the period.
The cyclonic circulation over the Andaman Sea has become a low pressure area and now lies in eastcentral Bay of Bengal with an associated cyclonic circulation up to medium levels. The weather system remains crucial for advancement of monsoon as systems like these expedite and enhance the progress of Southwest 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.
