Depression likely in Bay of Bengal in 24 hrs, uncertainty over cyclone formation
Posted on: 05/Dec/2017 2:25:01 PM
The well-marked low pressure area over southeast Bay of Bengal and adjoining south Andaman Sea continues to sustain its strength. In wake of this, heavy rains to extremely heavy rains have lashed southern parts of Andaman and Nicobar Islands.
Nancowry recorded 191 mm of rains in span of 24 hours from 8:30 am on Monday, followed by Car Nicobar with 147 mm.
According to Skymet Weather, the system remained practically stationary during the last 24 hours, getting more marked. The system would most likely continue to move in west-northwest direction.
Cloud configuration and atmospheric conditions are indicating towards intensification of the system into a depression by December 6 and further concentrating into a deep depression in subsequent 24-48 hours.
By December 7, the system is likely to re-curve in north-northwest direction towards Andhra Pradesh coast. Thus, with the weather system moving towards west-central Bay of Bengal, it will enter into cooler sea surface temperatures. Therefore, chances of intensification into a cyclonic remain bleak.
As the weather systems tracks further in Bay of Bengal, it will escape Tamil Nadu including Chennai. We expect mainly light rains with isolated moderate showers over Chennai on December 7. However, weather system would not have any impact in terms of heavy rains.
Meanwhile, coastal Andhra Pradesh and Odisha may receive moderate to heavy rain on December 7 and 8. With the system further tracking north, Gangetic West Bengal and Northeast India would also see light to moderate rains including Kolkata on December 8 and 9.
