'''Cyclonic Storm Yemyin''' (JTWC designation: '''''03B''''', also known as '''Deep Depression BOB 03/2007''') was a deadly [[tropical cyclone]] that made [[landfall]]s on India and Pakistan in June 2007. The [[Pakistan Meteorological Department]] referred to Tropical Cyclone 03B as "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 the storm. However, the IMD reassessed the system to have reached cyclonic storm strength, and retroactively named the storm Yemyin.<ref name="Yemyinname">[https://www.webcitation.org/5QzqpfB7g?url=http://www.imd.gov.in/section/nhac/dynamic/pressrelease.htm . "Yemyin" means Hippo in Myanmar (Burma) language]</ref>

Throughout three countries, 983 people were killed: 730 in Pakistan, 140 in India and 113 in Afghanistan. In all, the storm 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. Over the next few days, it developed deep flaring convection near an exposed low-level circulation centre (LLCC) as it drifted in open sea.<ref>[https://www.webcitation.org/5PiHAO2KX?url=http://metocph.nmci.navy.mil/jtwc/ab/abioweb.txt]</ref> Despite moderate to high vertical [[wind shear]], the disturbance produced [[atmospheric pressure|surface pressure]] falls of up to 2.7 [[millibar|mbar]] ([[Pascal (unit)|hPa]]) in [[Port Blair]], in the [[Andaman Islands]], on June 19.<ref name="webcitation.org">[https://www.webcitation.org/5PjPQ6WL4?url=http://metocph.nmci.navy.mil/jtwc/ab/abioweb.txt]</ref> Convection persisted around the increasingly well-defined LLCC, and the disturbance continued to consolidate under favourable [[diffluence (meteorology)|diffluence]].<ref name="webcitation.org"/><ref>[https://www.webcitation.org/5PjwZ4XDa?url=http://metocph.nmci.navy.mil/jtwc/ab/abioweb.txt]</ref>

Early on June 21, the [[India Meteorological Department]] (IMD) declared the area a depression, 430 km (270 mi) east-southeast of [[Kakinada]], [[Andhra Pradesh]], India.<ref name="BOB03IMD01">[https://www.webcitation.org/5Pl2aOcUc?url=http://www.imd.ernet.in/section/nhac/dynamic/rsmc.htm]</ref> Several hours later, the [[Joint Typhoon Warning Center]] (JTWC) issued a [[Tropical Cyclone Formation Alert]] (TCFA), with winds near 30 [[knot (unit)|kn]] (55 km/h, 35 mph).<ref name="BOB03TCFA">[https://www.webcitation.org/5Pl4nJpC7?url=http://metocph.nmci.navy.mil/jtwc/warnings/io952007web.txt]</ref> The depression moved quickly west-northwest towards the northern Andhra Pradesh coast.<ref name="BOB03IMD01"/> A [[subtropical ridge]] to the north weakened the wind shear which had been paralysing the system, allowing for further intensification.<ref name="BOB03TCFA"/> Later that day, the IMD upgraded the system to a deep depression.<ref>[https://www.webcitation.org/5PlZIXv7H?url=http://www.imd.ernet.in/section/nhac/dynamic/rsmc.htm]</ref> As convection organised with increasing ocean heat content, the JTWC issued its first warning on Tropical Cyclone 03B.<ref>[https://www.webcitation.org/5PlTDy9FR?url=http://metocph.nmci.navy.mil/jtwc/warnings/io032007web.txt]</ref> The deep depression made [[landfall]] near Kakinda early on June 22 local time.<ref>[https://www.webcitation.org/5PmEtgsyb?url=http://www.imd.ernet.in/section/nhac/dynamic/rsmc.htm]</ref> The JTWC issued its final advisory later, as the system began to weaken due to land interaction and wind shear.<ref>[https://www.webcitation.org/5Pme3GnZU?url=http://metocph.nmci.navy.mil/jtwc/warnings/io0307web.txt]</ref> The next day, the IMD downgraded it to a depression while it crossed the [[Deccan Plateau]].<ref>[https://www.webcitation.org/5Po29M4mA?url=http://www.imd.ernet.in/section/nhac/dynamic/rsmc.htm]</ref> 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 [[Southwest monsoon|monsoonal]] low-level flow contributed to increased cyclonic vorticity, with low vertical wind shear and warm [[sea surface temperatures]]. It warned that these factors could lead to a [[rapid intensification|rapid]] regeneration of the cyclone.<ref>[https://www.webcitation.org/5PpyFcKC8?url=http://metocph.nmci.navy.mil/jtwc/ab/abioweb.txt]</ref> Early on June 25, the JTWC issued the second TCFA for this system as its LLCC crossed the coast into the Arabian Sea.<ref>[https://www.webcitation.org/5Pr0NM4Fb?url=http://twister.sbs.ohio-state.edu/text/station/PGTW/ABIO10.PGTW]</ref> Shortly after, both the IMD<ref>[https://www.webcitation.org/5PrCgkooe?url=http://www.imd.ernet.in/section/nhac/dynamic/rsmc.htm]</ref> and the JTWC<ref>[https://www.webcitation.org/5PrR8Vrj6?url=http://metocph.nmci.navy.mil/jtwc/warnings/io0307web.txt]</ref> resumed advisories on the depression.

As it moved northwest just off the Pakistani coast, winds of about 26 kn (48 km/h, 30 mph) and a surface pressure of 990 mbar (hPa) were observed in [[Karachi]] near midday on June 25.<ref>[https://www.webcitation.org/5PrbCzNT4?url=http://metocph.nmci.navy.mil/jtwc/warnings/io0307web.txt]</ref> According to the PMD, the centre of the system reached within 90 km (55 mi) of Karachi.<ref name="Pakistan 03B"/> With favourable conditions and deep convection, the system intensified into a deep depression that day.<ref>[ftp://ftp.met.fsu.edu/pub/weather/tropical/New-Delhi/2007062516.DEMS]{{dead link|date=January 2017 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> After further organization, it made its second landfall at about 0300 UTC June 26 along the [[Makran]] coast, near [[Ormara]] and [[Pasni City|Pasni]], [[Balochistan (Pakistan)|Balochistan Province]], in southwestern Pakistan.<ref name="Pakistan 03B"/><ref>[https://www.webcitation.org/5PststKwZ?url=http://www.imd.ernet.in/section/nhac/dynamic/rsmc.htm]</ref><ref>[https://www.webcitation.org/5PstmCWco?url=http://metocph.nmci.navy.mil/jtwc/warnings/io0307web.txt]</ref> Upon reaching land, the cyclone began to weaken slowly,<ref>[ftp://ftp.met.fsu.edu/pub/weather/tropical/GuamStuff/2007062615-WTIO.PGTW]{{Dead link|date=July 2018 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> and the JTWC issued its last advisory late on June 26.<ref>[https://www.webcitation.org/5PuGtXmFM?url=http://metocph.nmci.navy.mil/jtwc/warnings/io0307web.txt]</ref>

===Afghanistan===
Over 80 people were killed in floods associated with the remnants of Yemyin in [[Afghanistan]].

==Naming==
Yemyin means Hippo in Myanmar. The PMD referred to the deep depression as Tropical Cyclone Yemyin, the next name on the list at the time.<ref name="Pakistan 03B"/> The IMD, the official [[Regional Specialized Meteorological Centre]] for the North Indian Ocean, did not operationally upgrade or name the system due to intense [[Indo-Pakistani relations]].<ref>{{cite web |url=http://scienceblogs.com/intersection/2007/06/cyclone_warfare_between_india.php |title=Cyclone Warfare Between India and Pakistan? : The Intersection |publisher=Scienceblogs.com |accessdate=2011-09-23 |archive-url=https://web.archive.org/web/20110826155828/http://scienceblogs.com/intersection/2007/06/cyclone_warfare_between_india.php |archive-date=2011-08-26 |url-status=dead }}</ref> However, on August 6, the IMD reassessed the deep depression to have reached cyclonic storm strength, and retroactively designated the system as Cyclonic Storm Yemyin in its mid-season review.<ref name="Yemyinname"/> This was confirmed by the designation of [[2007 North Indian Ocean cyclone season#Cyclonic Storm Sidr|Cyclonic Storm Sidr]], the next name on the list after Yemyin, in November.
