The Andaman and Nicobar Islands have been witnessing good rains for the last few days. In fact, a few hefty spells of rainfall were also recorded over the southern areas. All thanks to the persisting low pressure area which had been causing heavy rains in the region.
However, the system has now moved towards Sri Lanka coast and intensified into a depression and is likely to intensify into a deep depression. In fact, the possibility of its further intensification into a cyclone cannot be ruled out as well.
However, the system has no effect on the weather of the Andaman and Nicobar Islands which is why during the last 24 hours, almost no rainfall activity has been observed over the region except trace of rainfall over Port Blair.
Now, another low pressure is expected to appear in the Andaman Sea and under its influence, a depression is expected to form over in the Bay off Andaman and Nicobar Islands and adjoining areas.
Due to this weather system, moderate to heavy rain and thundershowers are expected to occur over Andaman and Nicobar Islands. In fact, the possibility of a few very heavy spells of rains cannot be ruled out over the region.
These showers will occur between November 30 and December 2. During this period, sea will remain rough and winds will gust up to 60 kmph along the coast. Thereafter, the weather system may intensify further and move towards North Tamil Nadu coast and give hefty showers over Chennai December 3 night onward.
