Track of TD ARB 02

Deep Depression ARB 02, or Tropical Cyclone 04A, began as a low pressure area over the Arabian Sea near 7.3°N and 70.7°E on 19 December. It slowly tracked westwards, organizing itself and intensifying into a Depression by 1100 UTC of 22 December.

The Joint Typhoon Warning Center (JTWC) upgraded the storm into a Tropical Cyclone by 0300 UTC of 23 December, followed by Deep Depression status by the morning hours of the same day. However the storm encountered a strong wind sheer on 24 December, causing its low-level circulation center to fully expose, prompting JTWC to issue the final advisory on the storm. Further weakening ensued, and the IMD downgraded ARB 02 into a low pressure area on 25 December.
