A low pressure area is being gradually formed in the Bay of Bengal. A look at the latest satellite image of the sea reveals massive clusters of disturbed weather and powerful thunderstorms. From this morass of clouds will emerge a rain system between Nicobar islands and the Indian mainland.
Global forecast models are divided over whether this low will intensify into a deep depression or tropical cyclone MAARUTHA. The American GFS is clear in portending a cyclone. It predicts a tropical storm nudging along the Myanmar coast bringing a deluge to these areas.
Other models expect a deep depression or a weak tropical storm to form in the next 48-72 hours. The system will move north northeasterly and head for the border of northern coastal Myanmar and Chittagong region of Bangladesh.
Whatever happens, Indian Andaman and Nicobar islands are in for a deluge in the coming days. Upto a metre of rainfall may occur. Tourists visiting these islands are advised to head to safer areas or leave for mainland India as soon as possible as the weather in the Bay of Bengal is going to be very disturbed in the next coming 5-7 days.
Disappointingly for drought hit Tamil Nadu the present expected storm system will not give it the much needed rain, though Sri Lanka will experience heavy showers under its influence.
Rains will come to Tamil Nadu by the end of this month, but it will be owing to another system.
The pink denotes areas of very heavy rainfall presently.
