Deep Depression ARB 01 (2013)

Deep Depression ARB 01 was the second deadliest tropical cyclone worldwide in 2013 as well as the deadliest to affect Somalia in recorded history. The sixth tropical cyclone and third deep depression of the 2013 North Indian Ocean cyclone season, ARB 01 formed in the Arabian Sea on November 8. The cyclone subsequently strengthened into a deep depression before making landfall in the Puntland region of Somalia at peak intensity on November 11. After making landfall, the cyclone rapidly weakened over land and degenerated into a well-marked low-pressure area later on the same day.

Although the cyclone remained weak throughout its life, torrential rainfall associated with the system killed 162 people across Somalia, and left about 300 others missing.
