• Associated cyclonic circulation extends up to 7.6 km above mean sea level.

• Expected to intensify into a depression over the South Andaman Sea within 24 hours.

• May further develop into a Cyclonic Storm over the South Bay of Bengal within the next 48 hours.

🔸 Upper Air Cyclonic Circulation (Comorin Area)

🔸 Cyclonic Circulation (Southeast Arabian Sea)
