Deep Depression BOB 03 and Cyclonic Storm Yemyin (JTWC designation: 03B) were a pair of deadly tropical cyclones that made landfalls on India and Pakistan in June 2007. The Pakistan Meteorological Department referred to both as Tropical Cyclone 03B, naming it "Tropical Cyclone Yemyin". At the time, the official WMO body responsible for tropical cyclones in the Arabian Sea, the India Meteorological Department (IMD), did not name them. However, the IMD reassessed the second system to have reached cyclonic storm strength, and retroactively named it Yemyin. Throughout three countries, 983 people were killed: 730 in Pakistan, 140 in India, and 113 in Afghanistan. In all, the storms wrought roughly $2.1 billion in damage in India and Pakistan. Meteorological history A low-pressure area associated with the monsoon trough was first detected by the Naval Research Laboratory in the Bay of Bengal on June 17. Over the next few days, it developed a deep flaring convection near an exposed low-level circulation centre (LLCC) as it drifted in the open sea. Despite moderate to high vertical wind shear, the disturbance produced surface pressure falls of up to 2.7 mbar (hPa) in Port Blair, in the Andaman Islands, on June 19. Convection persisted around the increasingly well-defined LLCC, and the disturbance continued to consolidate under favourable diffluence. Early on June 21, the India Meteorological Department (IMD) declared the area a depression, east-southeast of Kakinada, Andhra Pradesh, India. Several hours later, the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert (TCFA), with winds near . The depression moved quickly west-northwest towards the northern Andhra Pradesh coast. A subtropical ridge to the north weakened the wind shear which had been hindering the storm's development, allowing for further intensification. Later that day, the IMD upgraded the system to a deep depression. As convection organised with increasing ocean heat content, the JTWC issued its first warning on Tropical Cyclone 03B. The deep depression made landfall near Kakinda early on June 22 local time. The JTWC issued its final advisory later, as the system began to weaken due to land interaction and wind shear. The next day, the IMD downgraded it to a depression while it crossed the Deccan Plateau. The final warning was issued on June 24, despite the storm having moved into the Arabian Sea. The JTWC noted in its Significant Tropical Weather Outlook for the North Indian Ocean on June 24 that strong
