to a diarrhea outbreak. Deep Depression BOB 01 Originating from the monsoon trough, a low-pressure area formed just north of Sri Lanka on May 5. By 21:00 UTC that night, the system organized into a depression while moving west-northwestward toward India. It developed a central dense overcast of deep convection, prompting the IMD to upgrade it to a deep depression. Still associated with the monsoon, the system had several small circulations and gale-force winds. At 11:00 UTC on May 6, the system moved ashore Tamil Nadu near Cuddalore, and by the next day degenerated into a remnant low. Deep Depression BOB 02 The second deep depression formed on May 8 about 120 km (75 mi) southeast of the Andhra Pradesh coastline, north of the previous system. It moved to the northeast, intensifying into a deep depression on May 9. At 17:00 UTC that day, the system struck Andhra Pradesh near Tuni as it progressed northward, degenerating into a remnant low on May 10. Deep Depression BOB 03 The third deep depression was also the longest lasting. It formed on May 14 off the coast of Odisha, northeast of the previous system. Moving parallel to the coast, it also intensified into a deep depression on May 15. Early the next day, the system made landfall on Sagar Island in West Bengal state, and weakened while progressing northeastward into Bangladesh. On May 18, the depression was downgraded to a remnant low over Assam state. Depression BOB 04 (01B) On September 9, a tropical depression formed in the South China Sea in the west Pacific basin. Two days later, the system struck Vietnam and progressed westward through Indochina. The remnants entered the Bay of Bengal around September 13, accompanied by increasing convection. Moving to the west-northwest, the system resembled a monsoon depression at times, although the thunderstorms gradually became more concentrated. On September 16, the system developed into a depression, and on the same day the JTWC classified it as Tropical Cyclone 01B. As the system approached the Indian coastline, it developed good outflow, and was intensifying quickly. The JTWC estimated peak 1 minute winds of at 18:00 UTC on September 16. However, the IMD never assessed winds beyond . Around 01:00 UTC on September 17, the depression moved ashore India near Balasore, Odisha. That night, the system degenerated into a remnant low over Bihar, although the remnants persisted until September 20, when
