Going through a Rapid Intensification it has reached Extremely Severe Cyclonic Storm status sporting a wonderful eye after showing signs of Annular shape.
South Bay in the meanwhile has seen a broad area of disturbance persist along the Equatorial Waters between Sri Lanka & Sumatra. This broad area of disturbance now sports two circulations, one off Sri Lanka & the other near Banda Aceh, with models developing the one near Sri Lanka.
