'''Deep Depression BOB 03''' and '''Cyclonic Storm Yemyin'''{{efn|The name ''Yemyin'' ([[Burmese language|Burmese]]: ရေမြင်း; [[Help:IPA/Burmese|[jè.mjɪ́ɴ]]]) was contributed by [[Myanmar]] and means "[[hippopotamus]]" in [[Burmese language|Burmese]].}} (JTWC designation: '''''03B''''') were a pair of deadly [[tropical cyclone]]s that made [[landfall]]s 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.<ref name="Yemyinname">{{Cite web|url=http://www.imd.gov.in/section/nhac/dynamic/pressrelease.htm|title=SOUTHWEST MONSOON -2007|website=www.imd.gov.in}}</ref>

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.{{EM-DAT}}

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.
